When Bāṇāsura saw that his soldiers and commanders had been defeated, his anger only increased. He thought it wise to stop fighting with Sātyaki, Kṛṣṇa's commander in chief, and instead directly attack Lord Kṛṣṇa. Now having the opportunity to use his one thousand arms, he rushed toward Kṛṣṇa, simultaneously working five hundred bows and two thousand arrows. Such a foolish person could never measure Kṛṣṇa's strength. Immediately, without difficulty, Kṛṣṇa cut each of Bāṇāsura's bows into two pieces and, to check him from going further, made the horses of his chariot lie on the ground so that the chariot broke to pieces. After doing this, Kṛṣṇa blew His conchshell, Pāñcajanya.
There was a demigoddess named Koṭarā who was worshiped by Bāṇāsura, and their relationship was as mother and son. Mother Koṭarā was upset that Bāṇāsura's life was in danger, so she appeared on the scene. With naked body and scattered hair, she stood before Lord Kṛṣṇa. Śrī Kṛṣṇa did not like the sight of this naked woman, and to avoid seeing her He turned His face. Bāṇāsura, getting this chance to escape Kṛṣṇa's attack, left the battlefield. All the strings of his bows had been broken, and there was no chariot or driver, so he had no alternative but to return to his city. He lost everything in the battle.
Being greatly harassed by the arrows of Kṛṣṇa, all the associates of Lord Śiva—the hobgoblins and ghostly Bhūtas, Pretas and kṣatriyas—left the battlefield. Lord Śiva then took to his last resort. He released his greatest death weapon, known as Śiva-jvara, which destroys by excessive heat. It is said that at the end of creation the sun becomes twelve times more scorching than usual. This twelve-times-hotter temperature is called Śiva-jvara. When the Śiva-jvara personified was released, he had three heads and three legs, and as he came toward Kṛṣṇa it appeared that he was burning everything to ashes. He was so powerful that he made blazing fire appear in all directions, and Kṛṣṇa observed that he was specifically coming toward Him.
As there is a Śiva-jvara weapon, there is also a Nārāyaṇa-jvara weapon, which is represented by excessive cold. When there is excessive heat, one can somehow or other tolerate it, but when there is excessive cold, everything collapses. This is actually experienced by a person at the time of death. At the time of death, the temperature of the body first of all increases to 107 degrees Fahrenheit, and then the whole body collapses and immediately becomes as cold as ice. To counteract the scorching heat of the Śiva-jvara, there is no other weapon but the Nārāyaṇa-jvara.
Therefore, when Lord Kṛṣṇa saw that the Śiva-jvara had been released by Lord Śiva, He had no recourse other than to release the Nārāyaṇa-jvara. Lord Śrī Kṛṣṇa is the original Nārāyaṇa and the controller of the Nārāyaṇa-jvara weapon. When the Nārāyaṇa-jvara was released, there was a great fight between the two jvaras. When excessive heat is counteracted by extreme cold, it is natural for the hot temperature to gradually reduce, and this is what occurred in the fight between the Śiva-jvara and the Nārāyaṇa-jvara. Gradually, the Śiva-jvara's temperature diminished, and the Śiva-jvara began to cry for help from Lord Śiva, but Lord Śiva was unable to help him in the presence of the Nārāyaṇa-jvara. Unable to get any help from Lord Śiva, the Śiva-jvara could understand that he had no means of escape outside of surrendering unto Nārāyaṇa, Lord Kṛṣṇa Himself. Lord Śiva, the greatest of the demigods, could not help him, what to speak of the lesser demigods, and therefore the Śiva-jvara ultimately surrendered unto Kṛṣṇa, bowing before Him and offering a prayer so that the Lord might be pleased and give him protection.
This incident of the fight between the ultimate weapons of Lord Śiva and Lord Kṛṣṇa proves that if Kṛṣṇa gives someone protection no one can kill him and if Kṛṣṇa does not give one protection no one can save him. Lord Śiva is called Mahādeva, the greatest of all the demigods, although sometimes Lord Brahmā is considered the greatest of all the demigods because he can create. However, Lord Śiva can annihilate the creations of Brahmā. Still, both Lord Brahmā and Lord Śiva act only in one capacity: Lord Brahmā can create, and Lord Śiva can annihilate. But neither of them can maintain. Lord Viṣṇu, however, not only maintains but creates and annihilates also. Factually, the creation is not effected by Brahmā, because Brahmā himself is created by Lord Viṣṇu. And Lord Śiva is created, or born, of Brahmā. The Śiva-jvara thus understood that without Kṛṣṇa, or Nārāyaṇa, no one could help him. He therefore rightly took shelter of Lord Kṛṣṇa and, with folded hands, began to pray as follows.
"My dear Lord, I offer my respectful obeisances unto You because You have unlimited potencies. No one can surpass Your potencies, and thus You are the Lord of everyone. Generally people consider Lord Śiva the most powerful personality in the material world, but Lord Śiva is not all-powerful; You are all-powerful. This is factual. You are the original consciousness, or knowledge. Without knowledge, or consciousness, nothing can be powerful. A material thing may be very powerful, but without the touch of consciousness it cannot act. A material machine may be gigantic and wonderful, but without the touch of someone conscious and in knowledge, the material machine is useless for all purposes. My Lord, You are complete knowledge, and there is not a pinch of material contamination in Your personality. Lord Śiva may be a powerful demigod because of his specific power to annihilate the whole creation, and, similarly, Lord Brahmā may be very powerful because he can create the entire universe, but actually neither Brahmā nor Lord Śiva is the original cause of this cosmic manifestation. You are the Absolute Truth, the Supreme Brahman, and You are the original cause. The original cause of the cosmic manifestation is not the impersonal Brahman effulgence. That impersonal Brahman effulgence rests on Your personality." As confirmed in the Bhagavad-gītā, the cause of the impersonal Brahman is Lord Kṛṣṇa. This Brahman effulgence is likened to the sunshine, which emanates from the sun globe. Therefore, impersonal Brahman is not the ultimate cause. The ultimate cause of everything is the supreme eternal form of Kṛṣṇa. All material actions and reactions take place in the impersonal Brahman, but in the personal Brahman, the eternal form of Kṛṣṇa, there is no action and reaction.
The Śiva-jvara continued: “Therefore, my Lord, Your body is completely peaceful, completely blissful and devoid of material contamination. In the material body there are actions and reactions of the three modes of material nature. The time factor is the most important element, above all others, because the material manifestation is effected by the agitation of time. Thus natural phenomena come into existence, and as soon as phenomena appear, fruitive activities are visible. As the result of these fruitive activities, a living entity takes his form. He acquires a particular nature packed up in a subtle body and gross body formed by the life air, the ego, the ten sense organs, the mind and the five gross elements. These then create the type of body which later becomes the root cause of various other bodies, which are acquired one after another by means of the transmigration of the soul. All these phenomenal manifestations are the combined actions of Your material energy. You, however, are the cause of this external energy, and thus You remain unaffected by the action and reaction of the different elements. And because You are transcendental to such compulsions of material energy, You are the supreme tranquillity. You are the last word in freedom from material contamination. I therefore take shelter at Your lotus feet, giving up all other shelter.
“My dear Lord, Your appearance as the son of Vasudeva in Your role as a human being is one of the pastimes of Your complete freedom. To benefit Your devotees and vanquish the nondevotees, You appear in multi-incarnations. All such incarnations descend in fulfillment of Your promise in the Bhagavad-gītā that You appear as soon as there are discrepancies in the system of progressive life. When there are disturbances by irregular principles, my dear Lord, You appear by Your internal potency. Your main business is to protect and maintain the demigods and spiritually inclined persons and to maintain the standard of material law and order. Considering Your mission of maintaining such law and order, Your violence toward the miscreants and demons is quite befitting. This is not the first time You have incarnated; it is to be understood that You have done so many, many times before.
"My dear Lord, I beg to submit that I have been very greatly chastised by the release of Your Nārāyaṇa-jvara, which is certainly very cooling yet at the same time severely dangerous and unbearable for all of us. My dear Lord, as long as one is forgetful of Kṛṣṇa consciousness, driven by the spell of material desires and ignorant of the ultimate shelter at Your lotus feet, one who has accepted this material body becomes disturbed by the three miserable conditions of material nature. Because one does not surrender unto You, he continues to suffer perpetually."
After hearing the Śiva-jvara, Lord Kṛṣṇa replied, "O three-headed one, I am pleased with your statement. Be assured that there will be no more suffering for you from the Nārāyaṇa-jvara. Not only are you now free from fear of the Nārāyaṇa-jvara, but anyone in the future who simply recollects this fight between you and the Nārāyaṇa-jvara will also be freed from all kinds of fear." After hearing the Supreme Personality of Godhead, the Śiva-jvara offered respectful obeisances unto His lotus feet and left.
In the meantime, Bāṇāsura somehow or other recovered from his setbacks and, with rejuvenated energy, returned to fight. This time Bāṇāsura appeared before Lord Kṛṣṇa, who was seated on His chariot, with different kinds of weapons in his one thousand hands. Very much agitated, Bāṇāsura splashed his different weapons upon the body of Lord Kṛṣṇa like torrents of rain. When Lord Kṛṣṇa saw the weapons of Bāṇāsura coming at Him, like water coming out of a strainer, He took His sharp-edged Sudarśana disc and began to cut off the demon's one thousand arms, one after another, just as a gardener trims the twigs of a tree with sharp cutters. When Lord Śiva saw that his devotee Bāṇāsura could not be saved even in his presence, he came to his senses and personally came before Lord Kṛṣṇa and began to pacify Him by offering the following prayers.
Lord Śiva said, "My dear Lord, You are the worshipable object of the Vedic hymns. One who does not know You considers the impersonal brahma-jyotir to be the ultimate Supreme Absolute Truth, without knowledge that You exist behind Your spiritual effulgence in Your eternal abode. My dear Lord, You are therefore called Para-brahman. Indeed, the words paraṁ brahman have been used in the Bhagavad-gītā to identify You. Saintly persons who have completely cleansed their hearts of all material contamination can realize Your transcendental form, although You are all-pervading like the sky, unaffected by any material thing. Only the devotees can realize You, and no one else. In the impersonalists' conception of Your supreme existence, the sky is just like Your navel, fire is Your mouth, and water is Your semen. The heavenly planets are Your head, all the directions are Your ears, the earth (Urvī) is Your lotus feet, the moon is Your mind, and the sun is Your eye. As far as I am concerned, I act as Your ego. The ocean is Your abdomen, and the King of heaven, Indra, is Your arm. Trees and plants are the hairs on Your body, the clouds are the hair on Your head, and Lord Brahmā is Your intelligence. All the great progenitors, known as Prajāpatis, are Your symbolic representatives. And religion is Your heart. The impersonal feature of Your supreme body is conceived of in this way, but You are ultimately the Supreme Person. The impersonal feature of Your supreme body is only a small expansion of Your energy. You are likened to the original fire, and Your expansions are its light and heat."
