BG Chapters 1 - 6

The Kṛṣṇa conscious person observes fasting as it is recommended in the scriptures. He does not fast or eat more than is required, and he is thus competent to perform yoga practice.

BG 6.16, Purport:

Regulation of diet and sleep is recommended herein for the yogīs. Too much eating means eating more than is required to keep the body and soul together. There is no need for men to eat animals, because there is an ample supply of grains, vegetables, fruits and milk. Such simple foodstuff is considered to be in the mode of goodness according to the Bhagavad-gītā. Animal food is for those in the mode of ignorance. Therefore, those who indulge in animal food, drinking, smoking and eating food which is not first offered to Kṛṣṇa will suffer sinful reactions because of eating only polluted things. Bhuñjate te tv aghaṁ pāpā ye pacanty ātma-kāraṇāt. Anyone who eats for sense pleasure, or cooks for himself, not offering his food to Kṛṣṇa, eats only sin. One who eats sin and eats more than is allotted to him cannot execute perfect yoga. It is best that one eat only the remnants of foodstuff offered to Kṛṣṇa. A person in Kṛṣṇa consciousness does not eat anything which is not first offered to Kṛṣṇa. Therefore, only the Kṛṣṇa conscious person can attain perfection in yoga practice. Nor can one who artificially abstains from eating, manufacturing his own personal process of fasting, practice yoga. The Kṛṣṇa conscious person observes fasting as it is recommended in the scriptures. He does not fast or eat more than is required, and he is thus competent to perform yoga practice. One who eats more than required will dream very much while sleeping, and he must consequently sleep more than is required. One should not sleep more than six hours daily. One who sleeps more than six hours out of twenty-four is certainly influenced by the mode of ignorance. A person in the mode of ignorance is lazy and prone to sleep a great deal. Such a person cannot perform yoga.

BG Chapters 7 - 12

A brahmacārī has to live in the home of the spiritual master just like a servant, and he must beg alms from door to door and bring them to the spiritual master. He takes food only under the master's order, and if the master neglects to call the student for food that day, the student fasts.

BG 8.28, Translation and Purport:

A person who accepts the path of devotional service is not bereft of the results derived from studying the Vedas, performing sacrifices, undergoing austerities, giving charity or pursuing philosophical and fruitive activities. Simply by performing devotional service, he attains all these, and at the end he reaches the supreme eternal abode.

This verse is the summation of the Seventh and Eighth chapters, which particularly deal with Kṛṣṇa consciousness and devotional service. One has to study the Vedas under the guidance of the spiritual master and undergo many austerities and penances while living under his care. A brahmacārī has to live in the home of the spiritual master just like a servant, and he must beg alms from door to door and bring them to the spiritual master. He takes food only under the master's order, and if the master neglects to call the student for food that day, the student fasts. These are some of the Vedic principles for observing brahmacarya.

One may not be inclined to practice such fasting, but because of his determination to make advancement in the science of Kṛṣṇa consciousness, he should accept such bodily troubles when they are recommended. However, one should not fast unnecessarily or against Vedic injunctions.

BG 10.4-5, Purport:

Tuṣṭi, satisfaction, means that one should not be eager to gather more and more material goods by unnecessary activity. One should be satisfied with whatever is obtained by the grace of the Supreme Lord; that is called satisfaction. Tapas means austerity or penance. There are many rules and regulations in the Vedas which apply here, like rising early in the morning and taking a bath. Sometimes it is very troublesome to rise early in the morning, but whatever voluntary trouble one may suffer in this way is called penance. Similarly, there are prescriptions for fasting on certain days of the month. One may not be inclined to practice such fasting, but because of his determination to make advancement in the science of Kṛṣṇa consciousness, he should accept such bodily troubles when they are recommended. However, one should not fast unnecessarily or against Vedic injunctions. One should not fast for some political purpose; that is described in Bhagavad-gītā as fasting in ignorance, and anything done in ignorance or passion does not lead to spiritual advancement. Everything done in the mode of goodness does advance one, however, and fasting done in terms of the Vedic injunctions enriches one in spiritual knowledge.

SB Canto 1

Emperor Parīkṣit received the information of his death in time, and he at once left his kingdom and family and sat down on the bank of the Ganges to fast till death.

SB 1.3.42, Purport:

Emperor Parīkṣit received the information of his death in time, and he at once left his kingdom and family and sat down on the bank of the Ganges to fast till death. All great sages, ṛṣis, philosophers, mystics, etc., went there due to his imperial position. They offered many suggestions about his immediate duty, and at last it was settled that he would hear from Śukadeva Gosvāmī about Lord Kṛṣṇa. Thus the Bhāgavatam was spoken to him.

SB 1.4.10, Translation:

He was a great emperor and possessed all the opulences of his acquired kingdom. He was so exalted that he was increasing the prestige of the Pāṇḍu dynasty. Why did he give up everything to sit down on the bank of the Ganges and fast until death?

SB 1.19.6, Translation:

The river (Ganges, by which the King sat to fast) carries the most auspicious water, which is mixed with the dust of the lotus feet of the Lord and tulasī leaves. Therefore that water sanctifies the three worlds inside and outside and even sanctifies Lord Śiva and other demigods. Consequently everyone who is destined to die must take shelter of this river.

SB 1.19.7, Translation:

Thus the King, the worthy descendant of the Pāṇḍavas, decided once and for all and sat on the Ganges' bank to fast until death and give himself up to the lotus feet of Lord Kṛṣṇa, who alone is able to award liberation. So, freeing himself from all kinds of associations and attachments, he accepted the vows of a sage.

Although the King had already decided to fast until death on the bank of the Ganges, he humbly expressed his decision to elicit the opinions of the great authorities present there. Any decision, however important, should be confirmed by some authority.

SB 1.19.12, Translation and Purport:

After all the ṛṣis and others had seated themselves comfortably, the King, humbly standing before them with folded hands, told them of his decision to fast until death.

Although the King had already decided to fast until death on the bank of the Ganges, he humbly expressed his decision to elicit the opinions of the great authorities present there. Any decision, however important, should be confirmed by some authority. That makes the matter perfect. This means that the monarchs who ruled the earth in those days were not irresponsible dictators. They scrupulously followed the authoritative decisions of the saints and sages in terms of Vedic injunction. Mahārāja Parīkṣit, as a perfect king, followed the principles by consulting the authorities, even up to the last days of his life.

SB 1.19.18, Translation:

Thus the King, Mahārāja Parīkṣit, sat to fast until death. All the demigods of the higher planets praised the King's actions and in pleasure continually scattered flowers over the earth and beat celestial drums.

SB Canto 3

Starvation can be mitigated by drinking water. It is sometimes found that if a person who has taken a vow to fast takes a little water at intervals, the exhaustion of fasting is at once mitigated.

SB 3.26.43, Purport:

Starvation can be mitigated by drinking water. It is sometimes found that if a person who has taken a vow to fast takes a little water at intervals, the exhaustion of fasting is at once mitigated. In the Vedas it is also stated, āpomayaḥ prāṇaḥ: "Life depends on water." With water, anything can be moistened or dampened. Flour dough can be prepared with a mixture of water. Mud is made by mixing earth with water. As stated in the beginning of Śrīmad-Bhāgavatam, water is the cementing ingredient of different material elements. If we build a house, water is actually the constituent in making the bricks. Fire, water and air are the exchanging elements for the entire material manifestation, but water is most prominent. Also, excessive heat can be reduced simply by pouring water on the heated field.

One has to perform devotional service in full tapasya, austerity. One should fast on the two Ekādaśī days, which fall on the eleventh day of the waxing and waning moon, and on the birthdays of Lord Kṛṣṇa, Lord Rāma and Caitanya Mahāprabhu.

SB 3.27.22, Purport:

If one does not separate himself from material enjoyment, it is to be understood that he is not advancing in Kṛṣṇa consciousness. Renunciation in Kṛṣṇa consciousness is so strong that it cannot be deviated by any attractive illusion. One has to perform devotional service in full tapasya, austerity. One should fast on the two Ekādaśī days, which fall on the eleventh day of the waxing and waning moon, and on the birthdays of Lord Kṛṣṇa, Lord Rāma and Caitanya Mahāprabhu. There are many such fasting days. Yogena means "by controlling the senses and mind." Yoga indriya-saṁyamaḥ. Yogena implies that one is seriously absorbed in the self and is able, by development of knowledge, to understand his constitutional position in relationship with the Superself. In this way one becomes fixed in devotional service, and his faith cannot be shaken by any material allurement.

SB Canto 4

This does not mean that with our fasting the Lord should also fast. The Lord should be given foodstuff which is as nice as possible.

SB 4.8.72, Purport:

We should always remember that to become a bona fide devotee of the Lord is not an easy task, but in this age, by the mercy of Lord Caitanya, it has been made very easy. But if we do not follow even the liberal instructions of Lord Caitanya, how can we expect to discharge our regular duties in devotional service? It is not possible in this age to follow Dhruva Mahārāja in his austerity, but the principles must be followed; we should not disregard the regulative principles given by our spiritual master, for they make it easier for the conditioned soul. As far as our ISKCON movement is concerned, we simply ask that one observe the four prohibitive rules, chant sixteen rounds and, instead of indulging in luxurious eating for the tongue, simply accept prasāda offered to the Lord. This does not mean that with our fasting the Lord should also fast. The Lord should be given foodstuff which is as nice as possible. But we should not make it a point to satisfy our own tongues. As far as possible we should accept simple foodstuff, just to keep the body and soul together to execute devotional service.

According to the Vaiṣṇava calendar, there are many fasts, such as Ekādaśī and the appearance and disappearance days of God and His devotees. All of these are meant to decrease the fat within the body so that one will not sleep more than desired and will not become inactive and lazy.

SB 4.28.35-36, Purport:

We can definitely see that to advance in Kṛṣṇa consciousness one must control his bodily weight. If one becomes too fat, it is to be assumed that he is not advancing spiritually. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura severely criticized his fat disciples. The idea is that one who intends to advance in Kṛṣṇa consciousness must not eat very much. Devotees used to go to forests, high hills or mountains on pilgrimages, but such severe austerities are not possible in these days. One should instead eat only prasāda and no more than required. According to the Vaiṣṇava calendar, there are many fasts, such as Ekādaśī and the appearance and disappearance days of God and His devotees. All of these are meant to decrease the fat within the body so that one will not sleep more than desired and will not become inactive and lazy. Overindulgence in food will cause a man to sleep more than required. This human form of life is meant for austerity, and austerity means controlling sex, food intake, etc. In this way time can be saved for spiritual activity, and one can purify himself both externally and internally. Thus both body and mind can be cleansed.

SB Canto 6

Austerity involves observing fasts as fully as possible.

SB 6.1.13-14, Purport:

In the bhakti-mārga, the path of devotional service, one must strictly follow the regulative principles by first controlling the tongue (sevonmukhe hi jihvādau svayam eva sphuraty adaḥ (Brs. 1.2.234)). The tongue (jihvā) can be controlled if one chants the Hare Kṛṣṇa mahā-mantra, does not speak of any subjects other than those concerning Kṛṣṇa and does not taste anything not offered to Kṛṣṇa. If one can control the tongue in this way, brahmacarya and other purifying processes will automatically follow. It will be explained in the next verse that the path of devotional service is completely perfect and is therefore superior to the path of fruitive activities and the path of knowledge. Quoting from the Vedas, Śrīla Vīrarāghava Ācārya explains that austerity involves observing fasts as fully as possible (tapasānāśakena). Śrīla Rūpa Gosvāmī has also advised that atyāhāra, too much eating, is an impediment to advancement in spiritual life.

After continuing this process for one full year, the chaste wife should fast on the pūrṇimā, the full-moon day, of Kārttika.

SB 6.19 Summary:

If either a pregnant woman or her husband regularly discharges this devotional service, both of them will receive the result. After continuing this process for one full year, the chaste wife should fast on the pūrṇimā, the full-moon day, of Kārttika. On the following day, the husband should worship the Lord as before and then observe a festival by cooking nice food and distributing prasāda to the brāhmaṇas. Then, with the permission of the brāhmaṇas, the husband and wife should take prasāda. This chapter ends by glorifying the results of the puṁsavana function.

SB 6.19.21, Translation:

The chaste wife must perform such devotional service continuously for one year. After one year passes, she should fast on the full-moon day in the month of Kārttika (October-November).

SB Canto 7

In the Ādi-varāha Purāṇa it is said that a worshiper who has committed offenses may fast for one day at the holy place known as Śaukarava and then bathe in the Ganges.

SB 7.5.23-24, Purport:

If one commits any of the above offenses, one must read at least one chapter of Bhagavad-gītā. This is confirmed in the Skanda-Purāṇa, Avantī-khaṇḍa. Similarly, there is another injunction, stating that one who reads the thousand names of Viṣṇu can be released from all offenses. In the same Skanda-Purāṇa, Revā-khaṇḍa, it is said that one who recites prayers to tulasī or sows a tulasī seed is also freed from all offenses. Similarly, one who worships the śālagrāma-śilā can also be relieved of offenses. In the Brahmaṇḍa Purāṇa it is said that one who worships Lord Viṣṇu, whose four hands bear a conchshell, disc, lotus flower and club, can be relieved from the above offenses. In the Ādi-varāha Purāṇa it is said that a worshiper who has committed offenses may fast for one day at the holy place known as Śaukarava and then bathe in the Ganges.

Observing fasts on certain days of the month is one of the general principles to be followed by all human beings.

SB 7.11.8-12, Translation:

These are the general principles to be followed by all human beings: truthfulness, mercy, austerity (observing fasts on certain days of the month), bathing twice a day, tolerance, discrimination between right and wrong, control of the mind, control of the senses, nonviolence, celibacy, charity, reading of scripture, simplicity, satisfaction, rendering service to saintly persons, gradually taking leave of unnecessary engagements, observing the futility of the unnecessary activities of human society, remaining silent and grave and avoiding unnecessary talk, considering whether one is the body or the soul, distributing food equally to all living entities (both men and animals), seeing every soul (especially in the human form) as a part of the Supreme Lord, hearing about the activities and instructions given by the Supreme Personality of Godhead (who is the shelter of the saintly persons), chanting about these activities and instructions, always remembering these activities and instructions, trying to render service, performing worship, offering obeisances, becoming a servant, becoming a friend, and surrendering one's whole self. O King Yudhiṣṭhira, these thirty qualifications must be acquired in the human form of life. Simply by acquiring these qualifications, one can satisfy the Supreme Personality of Godhead.

A brahmacārī should accept prasāda upon the order of the spiritual master, and if the spiritual master sometimes forgets to order the disciple to eat, the disciple should not take prasāda on his own initiative; rather, he should fast.

SB 7.12 Summary:

The brahmacāri should live under the care of the true spiritual master, giving him sincere respect and obeisances, acting as his menial servant, and always carrying out his order. The brahmacārī should engage himself in spiritual activities and study the Vedic literature under the direction of the spiritual master. According to the brahmacarya system, he should dress with a belt, deerskin, and matted hair and should bear a daṇḍa, waterpot and sacred thread. He should collect alms daily in the morning, and in the evening whatever alms he has collected he should offer to the spiritual master. A brahmacārī should accept prasāda upon the order of the spiritual master, and if the spiritual master sometimes forgets to order the disciple to eat, the disciple should not take prasāda on his own initiative; rather, he should fast. The brahmacārī should be trained to be satisfied with eating what is absolutely necessary, he should be very expert in executing responsibilities, he should be faithful, and he should control his senses and try to avoid the association of women as far as possible. A brahmacārī should very strictly abstain from living with women and should not meet with gṛhasthas and those too addicted to women. Nor should a brahmacārī speak in a lonely place with a woman.

SB 7.12.5, Translation:

The brahmacārī should go out morning and evening to collect alms, and he should offer all that he collects to the spiritual master. He should eat only if ordered to take food by the spiritual master; otherwise, if the spiritual master does not give this order, he may sometimes have to fast.

SB Canto 8

The demigods and demons then observed a fast.

SB 8.9.14-15, Translation:

The demigods and demons then observed a fast. After bathing, they offered clarified butter and oblations into the fire and gave charity to the cows and to the brāhmaṇas and members of the other orders of society, namely the kṣatriyas, vaiśyas and śūdras, who were all rewarded as they deserved. Thereafter, the demigods and demons performed ritualistic ceremonies under the directions of the brāhmaṇas. Then they dressed themselves with new garments according to their own choice, decorated their bodies with ornaments, and sat facing east on seats made of kuśa grass.

SB Canto 9

On Dvādaśī, the day after Ekādaśī, when Mahārāja Ambarīṣa was about to break his Ekādaśī fast, the great mystic yogī Durvāsā appeared in his house and became his guest.

SB 9.4 Summary:

Once Mahārāja Ambarīṣa was worshiping the Supreme Personality of Godhead in Vṛndāvana, observing the vow of Dvādaśī. On Dvādaśī, the day after Ekādaśī, when he was about to break his Ekādaśī fast, the great mystic yogī Durvāsā appeared in his house and became his guest. King Ambarīṣa respectfully received Durvāsā Muni, and Durvāsā Muni, after accepting his invitation to eat there, went to bathe in the Yamunā River at noontime. Because he was absorbed in samādhi, he did not come back very soon. Mahārāja Ambarīṣa, however, upon seeing that the time to break the fast was passing, drank a little water, in accordance with the advice of learned brāhmaṇas, just to observe the formality of breaking the fast. By mystic power, Durvāsā Muni could understand that this had happened, and he was very angry. When he returned he began to chastise Mahārāja Ambarīṣa, but he was not satisfied, and finally he created from his hair a demon appearing like the fire of death. The Supreme Personality of Godhead, however, is always the protector of His devotee, and to protect Mahārāja Ambarīṣa, He sent His disc, the Sudarśana cakra, which immediately vanquished the fiery demon and then pursued Durvāsā, who was so envious of Mahārāja Ambarīṣa.

SB 9.4.30, Translation:

In the month of Kārtika, after observing that vow for one year, after observing a fast for three nights and after bathing in the Yamunā, Mahārāja Ambarīṣa worshiped the Supreme Personality of Godhead, Hari, in Madhuvana.

After giving these cows, the King first sumptuously fed all the brāhmaṇas, and when they were fully satisfied, he was about to observe the end of Ekādaśī, with their permission, by breaking the fast.

SB 9.4.33-35, Translation:

Thereafter, Mahārāja Ambarīṣa satisfied all the guests who arrived at his house, especially the brāhmaṇas. He gave in charity sixty crores of cows whose horns were covered with gold plate and whose hooves were covered with silver plate. All the cows were well decorated with garments and had full milk bags. They were mild-natured, young and beautiful and were accompanied by their calves. After giving these cows, the King first sumptuously fed all the brāhmaṇas, and when they were fully satisfied, he was about to observe the end of Ekādaśī, with their permission, by breaking the fast. Exactly at that time, however, Durvāsā Muni, the great and powerful mystic, appeared on the scene as an uninvited guest.

SB 9.4.38, Translation:

In the meantime, only a muhūrta of the Dvādaśī day was left on which to break the fast. Consequently, it was imperative that the fast be broken immediately. In this dangerous situation, the King consulted learned brāhmaṇas.

The King said. "O brāhmaṇas, if you think that it will be auspicious and not irreligious, I shall break the fast by drinking water."

SB 9.4.39-40, Translation:

The King said: "To transgress the laws of respectful behavior toward the brāhmaṇas is certainly a great offense. On the other hand, if one does not observe the breaking of the fast within the time of Dvādaśī, there is a flaw in one's observance of the vow. Therefore, O brāhmaṇas, if you think that it will be auspicious and not irreligious, I shall break the fast by drinking water." In this way, after consulting with the brāhmaṇas, the King reached this decision, for according to brahminical opinion, drinking water may be accepted as eating and also as not eating.

SB 9.5.23, Translation:

Durvāsā Muni had left the place of Mahārāja Ambarīṣa, and as long as he had not returned—for one complete year—the King had fasted, maintaining himself simply by drinking water.

SB 9.9.6, Purport:

Devotees and saintly persons advanced in the renounced order can deliver even the Ganges. Tīrthī-kurvanti tīrthāni svāntaḥ-sthena gadābhṛtā (SB 1.13.10). Because saintly devotees always keep the Lord within the core of their hearts, they can perfectly cleanse the holy places of all sinful reactions. Therefore, people in general must always respectfully honor saintly persons. It is ordered that as soon as one sees a Vaiṣṇava, or even a sannyāsī, one should immediately offer respects to such a holy man. If one forgets to show respect in this way, one must observe a fast for that day. This is a Vedic injunction. One must be extremely careful to refrain from committing offenses at the lotus feet of a devotee or saintly person.

After reaching the beach, Lord Rāmacandra fasted for three days, awaiting the arrival of the ocean personified.

SB 9.10.13, Translation:

After reaching the beach, Lord Rāmacandra fasted for three days, awaiting the arrival of the ocean personified. When the ocean did not come, the Lord exhibited His pastimes of anger, and simply by His glancing over the ocean, all the living entities within it, including the crocodiles and sharks, were agitated by fear. Then the personified ocean fearfully approached Lord Rāmacandra, taking all paraphernalia to worship Him. Falling at the Lord's lotus feet, the personified ocean spoke as follows.

Rantideva was so exalted that he would sometimes give away his own food in charity, and he and his family would fast.

SB 9.21 Summary:

As an exalted devotee, Rantideva saw every living entity in relationship with the Supreme Personality of Godhead, and therefore he completely engaged his mind, his words and his very self in the service of the Supreme Lord and His devotees. Rantideva was so exalted that he would sometimes give away his own food in charity, and he and his family would fast. Once, after Rantideva spent forty-eight days fasting, not even drinking water, excellent food made with ghee was brought to him, but when he was about to eat it a brāhmaṇa guest appeared. Rantideva, therefore, did not eat the food, but instead immediately offered a portion of it to the brāhmaṇa. When the brāhmaṇa left and Rantideva was just about to eat the remnants of the food, a śūdra appeared. Rantideva therefore divided the remnants between the śūdra and himself. Again, when he was just about to eat the remnants of the food, another guest appeared. Rantideva therefore gave the rest of the food to the new guest and was about to content himself with drinking the water to quench his thirst, but this also was precluded, for a thirsty guest came and Rantideva gave him the water. This was all ordained by the Supreme Personality of Godhead just to glorify His devotee and show how tolerant a devotee is in rendering service to the Lord.

SB Canto 10.1 to 10.13

Despite his fast, Mahārāja Parīkṣit was not at all fatigued. "The hunger and thirst from my fast do not disturb me," he said.

SB 10.1.13, Purport:

To prepare to meet death in seven days, Mahārāja Parīkṣit gave up all food and drink. As a human being, he was certainly both hungry and thirsty, and therefore Śukadeva Gosvāmī might have wanted to stop narrating the transcendental topics of Kṛṣṇa; but despite his fast, Mahārāja Parīkṣit was not at all fatigued. "The hunger and thirst from my fast do not disturb me," he said. "Once when I felt very thirsty, I went to the āśrama of Śamīka Muni to drink water, but the muni did not supply it. I therefore wrapped a dead snake over his shoulder, and that is why I was cursed by the brāhmaṇa boy. Now, however, I am quite fit. I am not at all disturbed by my hunger and thirst." This indicates that although on the material platform there are disturbances from hunger and thirst, on the spiritual platform there is no such thing as fatigue.

SB Cantos 10.14 to 12 (Translations Only)

SB 10.16.62, Translation:

If one bathes in this place of My pastimes and offers the water of this lake to the demigods and other worshipable personalities, or if one observes a fast and duly worships and remembers Me, he is sure to become free from all sinful reactions.

SB 10.28.1, Translation:

Śrī Bādarāyaṇi said: Having worshiped Lord Janārdana and fasted on the Ekādaśī day, Nanda Mahārāja entered the water of the Kālindī on the Dvādaśī to take his bath.

SB 10.34.4, Translation:

Nanda, Sunanda and the other greatly fortunate cowherds spent that night on the bank of the Sarasvatī, strictly observing their vows. They fasted, taking only water.

SB 10.82.9, Translation:

At Samanta-pañcaka, the saintly Yādavas bathed and then observed a fast with careful attention. Afterward they presented brāhmaṇas with cows bedecked with garments, flower garlands and gold necklaces.

SB 11.8.3, Translation:

SB 11.30.7, Translation:

There we should bathe for purification, fast, and fix our minds in meditation. We should then worship the demigods by bathing their images, anointing them with sandalwood pulp, and presenting them various offerings.

Only when his spiritual master invited him would Mārkaṇḍeya Ṛṣi silently take his one meal of the day; otherwise he would fast.

SB 12.8.7-11, Translation:

After being purified by his father's performance of the prescribed rituals leading to Mārkaṇḍeya's brahminical initiation, Mārkaṇḍeya studied the Vedic hymns and strictly observed the regulative principles. He became advanced in austerity and Vedic knowledge and remained a lifelong celibate. Appearing most peaceful with his matted hair and his clothing made of bark, he furthered his spiritual progress by carrying the mendicant's waterpot, staff, sacred thread, brahmacārī belt, black deerskin, lotus-seed prayer beads and bundles of kuśa grass. At the sacred junctures of the day he regularly worshiped the Supreme Personality of Godhead in five forms—the sacrificial fire, the sun, his spiritual master, the brāhmaṇas and the Supersoul within his heart. Morning and evening he would go out begging, and upon returning he would present all the food he had collected to his spiritual master. Only when his spiritual master invited him would he silently take his one meal of the day; otherwise he would fast. Thus devoted to austerity and Vedic study, Mārkaṇḍeya Ṛṣi worshiped the supreme master of the senses, the Personality of Godhead, for countless millions of years, and in this way he conquered unconquerable death.

SB 12.12.6, Translation:

Also described are saintly King Parīkṣit's sitting down to fast until death in response to the curse of a brāhmaṇa's son, and the conversations between Parīkṣit and Śukadeva Gosvāmī, who is the best of all brāhmaṇas.

SB 12.12.61, Translation:

One who controls his mind, fasts at the holy places Puṣkara, Mathurā or Dvārakā, and studies this scripture will be freed from all fear.
