SB Canto 4

In this age of Kali there are no powerful brāhmaṇas who can invite the demigods or give renewed life to animals. Formerly, the brāhmaṇas well conversant in Vedic mantras could show the potency of the mantras, but in this age, because there are no such brāhmaṇas, all such sacrifices are forbidden.

SB 4.13.25, Translation and Purport:

Śrī Maitreya replied: My dear Vidura, once the great King Aṅga arranged to perform the great sacrifice known as aśvamedha. All the expert brāhmaṇas present knew how to invite the demigods, but in spite of their efforts, no demigods participated or appeared in that sacrifice.

A Vedic sacrifice is not an ordinary performance. The demigods used to participate in such sacrifices, and the animals sacrificed in such performances were reincarnated with new life. In this age of Kali there are no powerful brāhmaṇas who can invite the demigods or give renewed life to animals. Formerly, the brāhmaṇas well conversant in Vedic mantras could show the potency of the mantras, but in this age, because there are no such brāhmaṇas, all such sacrifices are forbidden. The sacrifice in which horses were offered was called aśvamedha. Sometimes cows were sacrificed (gavālambha), not for eating purposes, but to give them new life in order to show the potency of the mantra. In this age, therefore, the only practical yajña is saṅkīrtana-yajña, or chanting of the Hare Kṛṣṇa mantra twenty-four hours a day.

SB Canto 5

There was no purpose in killing the animal. Actually the animal was offered in the sacrificial fire to get a rejuvenated life. Generally an old animal was sacrificed in the fire. and it would come out again in a youthful body. Some of the rituals however, did not require animal sacrifice. In the present age, animal sacrifices are forbidden.

SB 5.7.5, Translation and Purport:

With great faith King Bharata performed various kinds of sacrifice. He performed the sacrifices known as agni-hotra, darśa, pūrṇamāsa, cāturmāsya, paśu-yajña (wherein a horse is sacrificed) and soma-yajña (wherein a kind of beverage is offered). Sometimes these sacrifices were performed completely and sometimes partially. In any case, in all the sacrifices the regulations of cāturhotra were strictly followed. In this way Bharata Mahārāja worshiped the Supreme Personality of Godhead.

Animals like hogs and cows were offered in sacrifice to test the proper execution of the sacrifice. Otherwise, there was no purpose in killing the animal. Actually the animal was offered in the sacrificial fire to get a rejuvenated life. Generally an old animal was sacrificed in the fire. and it would come out again in a youthful body. Some of the rituals however, did not require animal sacrifice. In the present age, animal sacrifices are forbidden. As stated by Śrī Caitanya Mahāprabhu:

aśvamedhaṁ gavālambhaṁ

sannyāsaṁ pala-paitṛkam

devareṇa sutotpattiṁ

kalau pañca vivarjayet

"In this age of Kali, five acts are forbidden: the offering of a horse in sacrifice, the offering of a cow in sacrifice, the acceptance of the order of sannyāsa, the offering of oblations of flesh to the forefathers, and a man's begetting children in his brother's wife." (CC Adi 17.164) Such sacrifices are impossible in this age due to the scarcity of expert brāhmaṇas or ṛtvijaḥ who are able to take the responsibility. In the absence of these, the saṅkīrtana-yajña is recommended. Yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ (SB 11.5.32). After all, sacrifices are executed to please the Supreme Personality of Godhead. Yajñārtha-karma: such activities should be carried out for the Supreme Lord's pleasure. In this age of Kali, the Supreme Lord in His incarnation of Śrī Caitanya Mahāprabhu should be worshiped with His associates by performance of saṅkīrtana-yajña, the congregational chanting of the Hare Kṛṣṇa mantra. This process is accepted by intelligent men. Yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ. The word sumedhasaḥ refers to intelligent men who possess very good brain substance.

Bhagavad-gita As It Is Lectures

Whether the brāhmaṇas who were engaged in offering sacrifice, whether they were chanting the Vedic mantra in right way, that was tested by offering one animal and again giving the animal a new youth life. That was animal sacrifice. Sometimes horses, sometimes cows were offered. But in this age, Kali-yuga, they are forbidden because there is no such yājñika-brāhmaṇa.

Lecture on BG 2.2-6 -- Ahmedabad, December 11, 1972:

The kṣatriyas, when they are fighting in the battlefield, the killing is not a sin for them. Similarly, a brāhmaṇa, when he's offering sacrifice, sometimes animals are sacrificed; so that does not mean that he is committing sin. This animal sacrifice was made not for eating the animals. It was for testing the Vedic mantra. Whether the brāhmaṇas who were engaged in offering sacrifice, whether they were chanting the Vedic mantra in right way, that was tested by offering one animal and again giving the animal a new youth life. That was animal sacrifice. Sometimes horses, sometimes cows were offered. But in this age, Kali-yuga, they are forbidden because there is no such yājñika-brāhmaṇa. All kinds of sacrifices are forbidden in this age.

aśvamedhaṁ gavālambhaṁ

sannyāsaṁ pala-paitṛkam

devareṇa sutotpattiṁ

kalau pañca vivarjayet

(CC Adi 17.164)

Aśvamedha sacrifice, gomedha sacrifice, sannyāsa, and to get child by devara, husband's younger brother, these things are forbidden in this age.

Sri Isopanisad Lectures

The animal killing is there in the Vedas, but what the purpose? That is to test the Vedic mantra. An animal will be put into the fire, and by Vedic mantra he'll be rejuvenated. That is sacrifice, animal sacrifice. Not that for eating purpose. Therefore in this age of Kali, Caitanya Mahāprabhu has forbidden any kind of yajña because there is no, I mean to say, expert brāhmaṇa who can chant the mantras and make experiment of the Vedic mantras that "Here is coming out."

Sri Isopanisad, Mantra 1 -- Los Angeles, May 3, 1970:

So Lord Buddha, he cheated the demons. Why he cheated? Sadaya-hṛdaya darśita-paśu-ghātam. He was very compassionate. God is always sympathetic to all living entities because everyone is His son. So these rascals were killing unrestrictedly, simply animal-killing... And if you say, "Oh, why you are animal-killing?" they will immediately say, "Oh, it is in the Vedas: paśavo vadhāya sṛṣṭa." The animal killing is there in the Vedas, but what the purpose? That is to test the Vedic mantra. An animal will be put into the fire, and by Vedic mantra he'll be rejuvenated. That is sacrifice, animal sacrifice. Not that for eating purpose. Therefore in this age of Kali, Caitanya Mahāprabhu has forbidden any kind of yajña because there is no, I mean to say, expert brāhmaṇa who can chant the mantras and make experiment of the Vedic mantras that "Here is coming out." That is... Before performing yajña, how the mantra is potent, that was tested by sacrificing animal and again giving new life. Then it is to be understood that the priests who were chanting that mantra, that is right. That was a test. Not for animal-killing. But these rascals, for eating animals they cited, "Here, there is animal-killing." Just like in Calcutta... You have been in Calcutta? And there is a street, College Street. Now it is differently named. I think it is named Vidhan Raya (?). Just like... Anyway, so there are some slaughterhouses. So slaughterhouses means the Hindus, they do not purchase meat from Muslims' shop. That is impure. (laughter) The same thing: stool this side and that side. They are eating meat, and Hindu shop is pure, Muslim shop is impure. These are mental concoction. Religion is going on like that.

Wedding Ceremonies

Aśvamedha yajña, gomedha yajña is also forbidden, because there is no yajñic brāhmaṇas. Formerly when an animal was put into the fire, sacrificed, and by Vedic mantra it was given a new, fresh life. That was the test of Vedic mantra pronouncing. But that is not possible nowadays. In the Kali-yuga, the only yajña is the sañkīrtana yajña.

Wedding Lecture -- November 17, 1971, New Delhi:

So marriage is essential. So far our society is concerned, we don't allow anybody to remain in our society as friends, girlfriend or boyfriend. No. They must be married. And these boys and girls, after being married, they are preaching nicely Kṛṣṇa consciousness. All my students who are married, they are doing preaching work more than sannyāsī. Yes. In the Kali-yuga, practically it is forbidden. Sannyāsaṁ pala-paitṛkam kalau pañca vivarjayet, aśvamedhaṁ gavālambhaṁ.

aśvamedhaṁ gavālambhaṁ

sannyāsaṁ pala-paitṛkam

devareṇa sutotpattiṁ

kalau pañca vivarjayet

(CC Adi 17.164)

Formerly there was a system: if the husband is unable, then a son can be begotten by the husband's younger brother, devareṇa. But in this age, Kali-yuga, that is forbidden. Similarly, aśvamedha yajña, gomedha yajña is also forbidden, because there is no yajñic brāhmaṇas. Formerly when an animal was put into the fire, sacrificed, and by Vedic mantra it was given a new, fresh life. That was the test of Vedic mantra pronouncing. But that is not possible nowadays. In the Kali-yuga, the only yajña is the sañkīrtana yajña.

kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ

sāṅgopāṅgāstra-pārṣadam

yajñaiḥ saṅkīrtana-prāyair

yajanti hi su-medhasaḥ

(SB 11.5.32)

Those who are highly intellectual, su-medhasaḥ, they perform the saṅkīrtana yajña, and by that saṅkīrtana yajña, the Lord, whose complexion is not black and who is always chanting Hare Kṛṣṇa mantra and is accompanied by His associates, sāṅgopāṅgāstra-pārṣadam, yajñaiḥ saṅkīrtana-prāyair yajanti hi su-medhasaḥ.

General Lectures

Animal sacrifice means to prove the strength of Vedic hymns so that one old animal is put into the fire and he's given again a new life, renewed life, just to show the potency of the hymns, Vedic hymns. But in this age, Kali-yuga, those sacrifices are forbidden.

Lecture (Day after Lord Rama's Appearance Day) -- Los Angeles, April 16, 1970:

In the Vedic literature there are numerous prescription of sacrifice. And in some of the sacrifices animal sacrifice is also recommended. So that animal sacrifice does not mean to kill the animal. Animal sacrifice means to prove the strength of Vedic hymns so that one old animal is put into the fire and he's given again a new life, renewed life, just to show the potency of the hymns, Vedic hymns. But in this age, Kali-yuga, those sacrifices are forbidden. So Lord Buddha, when he saw that people are sacrificing animals in the name of religious rituals without any pity for them, at that time Lord Buddha appeared. Therefore it is stated, sadaya-hṛdaya-darśita-paśu-ghātam: "My dear Lord, You have appeared as Lord Buddha, just being compassionate to the poor animals."
