The Lord says in Bhagavad-gītā (4.6):

“Although I am unborn and My transcendental body never deteriorates, and although I am the Lord of all sentient beings, I still appear in every millennium in My original transcendental form.” In the following verse in Bhagavad-gītā (4.7), the Lord says:

“Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion — at that time I descend Myself.” Thus although the Supreme Lord is unborn, there is no cessation to His appearance in different forms as incarnations like Lord Kṛṣṇa and Lord Rāma. Since His incarnations are eternal, the various activities performed by these incarnations are also eternal. The Supreme Personality of Godhead does not appear because He is forced to do so by karma like ordinary living entities who are forced to accept a certain type of body. It is to be understood that the Lord’s body and activities are all transcendental, being free from the contamination of the material modes of nature. These pastimes are transcendental bliss to the Lord. The word aparigaṇya-dhāmne is very significant. There is no limit to the Lord’s appearance in different incarnations. All of these incarnations are eternal, blissful and full of knowledge.

The Vedic mantras say: yasmin vijñāte sarvam evaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). When the devotee sees the Supreme Personality of Godhead by his meditation, or when he sees the Lord personally, face to face, he becomes aware of everything within this universe. Indeed, nothing is unknown to him. Everything within this material world is fully manifested to a devotee who has seen the Supreme Personality of Godhead. Bhagavad-gītā (4.34) therefore advises:

“Just try to learn the truth by approaching a spiritual master. Inquire from him submissively and render service unto him. The self-realized soul can impart knowledge unto you because he has seen the truth.” Lord Brahmā is one of these self-realized authorities (svayambhūr nāradaḥ śambhuḥ kumāraḥ kapilo manuḥ). One must therefore accept the disciplic succession from Lord Brahmā, and then one can understand the Supreme Personality of Godhead in fullness. Here the word viśva-mūrtau indicates that everything exists in the form of the Supreme Personality of Godhead. One who is able to worship Him can see everything in Him and see Him in everything.

The Lord says in Bhagavad-gītā (9.10):

“This material nature, working under My direction, O son of Kuntī, is producing all moving and unmoving beings. By its rule this manifestation is created and annihilated again and again.” The material energy creates, maintains and devastates the entire cosmic manifestation because of directions given by the Supreme Personality of Godhead, who enters this universe as Garbhodakaśāyī Viṣṇu but is untouched by the material qualities. In Bhagavad-gītā the Lord refers to māyā, the external energy, which creates this material world, as mama māyā, “My energy,” because this energy works under the full control of the Lord. These facts can be realized only by those who are well versed in Vedic knowledge and advanced in Kṛṣṇa consciousness.

Although the Supreme Personality of Godhead is nirguṇa, not to be found within this material world, the entire material world is pervaded by Him, as stated in Bhagavad-gītā (mayā tatam idaṁ sarvam). The material world is nothing but an expansion of the Lord’s material energy, and the entire cosmic manifestation rests upon Him (mat-sthāni sarva-bhūtāni). Nonetheless, the Supreme Lord cannot be found here (na cāhaṁ teṣv avasthitaḥ). A devotee, however, can see the Supreme Personality of Godhead through the practice of bhakti-yoga. One ordinarily does not begin to practice bhakti-yoga unless he has practiced it in previous births. Moreover, one can begin bhakti-yoga only by the mercy of the spiritual master and Kṛṣṇa. Guru-kṛṣṇa-prasāde pāya bhakti-latā-bīja. The seed of devotional service is obtainable by the mercy of guru, the spiritual master, and Kṛṣṇa, the Supreme Personality of Godhead.

Only by the practice of bhakti-yoga can one achieve the favor of the Supreme Personality of Godhead and see Him face to face (premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti). One cannot see the Lord by other methods, such as karma, jñāna or yoga. Under the direction of the spiritual master, one must cultivate bhakti-yoga (śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam). Then, even within this material world, although the Lord is not visible, a devotee can see Him. This is confirmed in Bhagavad-gītā (bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ) and in Śrīmad-Bhāgavatam (bhaktyāham ekayā grāhyaḥ). Thus by devotional service one can achieve the favor of the Supreme Personality of Godhead, although He is not visible or understandable to materialistic persons.

In this verse, the cultivation of bhakti-yoga is compared to many material activities. By friction one can get fire from wood, by digging the earth one can get food grains and water, and by agitating the milk bag of the cow one can get nectarean milk. Milk is compared to nectar, which one can drink to become immortal. Of course, simply drinking milk will not make one immortal, but it can increase the duration of one’s life. In modern civilization, men do not think milk to be important, and therefore they do not live very long. Although in this age men can live up to one hundred years, their duration of life is reduced because they do not drink large quantities of milk. This is a sign of Kali-yuga. In Kali-yuga, instead of drinking milk, people prefer to slaughter an animal and eat its flesh. The Supreme Personality of Godhead, in His instructions of Bhagavad-gītā, advises go-rakṣya, which means cow protection. The cow should be protected, milk should be drawn from the cows, and this milk should be prepared in various ways. One should take ample milk, and thus one can prolong one’s life, develop his brain, execute devotional service, and ultimately attain the favor of the Supreme Personality of Godhead. As it is essential to get food grains and water by digging the earth, it is also essential to give protection to the cows and take nectarean milk from their milk bags.

The people of this age are inclined toward industrial enterprises for comfortable living, but they refuse to endeavor to execute devotional service, by which they can achieve the ultimate goal of life by returning home, back to Godhead. Unfortunately, as it is said, na te viduḥ svārtha-gatiṁ hi viṣṇuṁ durāśayā ye bahir-artha-māninaḥ. People without spiritual education do not know that the ultimate goal of life is to go back home, back to Godhead. Forgetting this aim of life, they are working very hard in disappointment and frustration (moghāśā mogha-karmāṇo mogha jñānā vicetasaḥ). The so-called vaiśyas — the industrialists or businessmen — are involved in big, big industrial enterprises, but they are not interested in food grains and milk. However, as indicated here, by digging for water, even in the desert, we can produce food grains; when we produce food grains and vegetables, we can give protection to the cows; while giving protection to the cows, we can draw from them abundant quantities of milk; and by getting enough milk and combining it with food grains and vegetables, we can prepare hundreds of nectarean foods. We can happily eat this food and thus avoid industrial enterprises and joblessness.

Agriculture and cow protection are the way to become sinless and thus be attracted to devotional service. Those who are sinful cannot be attracted by devotional service. As stated in Bhagavad-gītā (7.28):

“Persons who have acted piously in previous lives and in this life, whose sinful actions are completely eradicated and who are freed from the duality of delusion, engage themselves in My service with determination.” The majority of people in this Age of Kali are sinful, short-living, unfortunate and disturbed (mandāḥ sumanda-matayo manda-bhāgyā hy upadrutāḥ). For them, Caitanya Mahāprabhu has advised:

“In this age of quarrel and hypocrisy the only means of deliverance is chanting the holy name of the Lord. There is no other way. There is no other way. There is no other way.”

The devotees of the Lord are always very eager to see the Supreme Lord face to face, but they do not demand that the Lord come before them, for a pure devotee considers such a demand to be contrary to devotional service. Śrī Caitanya Mahāprabhu teaches this lesson in His Śikṣāṣṭaka. Adarśanān marma-hatāṁ karotu vā. The devotee is always eager to see the Lord face to face, but if he is brokenhearted because he cannot see the Lord, even life after life, he will never command the Lord to appear. This is a sign of pure devotion. Therefore in this verse we find the word ati-cira-īpsita-artham, meaning that the devotee aspires for a long, long time to see the Lord. If the Lord, by His own pleasure, appears before the devotee, the devotee feels extremely happy, as Dhruva Mahārāja felt when he personally saw the Supreme Personality of Godhead. When Dhruva Mahārāja saw the Lord, he had no desire to ask the Lord for any benediction. Indeed, simply by seeing the Lord, Dhruva Mahārāja felt so satisfied that he did not want to ask the Lord for any benediction (svāmin kṛtārtho ’smi varaṁ na yāce). A pure devotee, whether able or unable to see the Lord, always engages in the Lord’s devotional service, always hoping that at some time the Lord may be pleased to appear before him so that he can see the Lord face to face.

As stated in Bhagavad-gītā (13.3), kṣetra-jñaṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata. The individual souls are proprietors of their individual bodies, but the Supreme Personality of Godhead is the proprietor of all bodies. Since He is the witness of everyone’s body, nothing is unknown to Him. He knows what we need. Our duty, therefore, is to execute devotional service sincerely, under the direction of the spiritual master. Kṛṣṇa, by His grace, will supply whatever we need in executing our devotional service. In the Kṛṣṇa consciousness movement, we simply have to execute the order of Kṛṣṇa and guru. Then all necessities will be supplied by Kṛṣṇa, even if we do not ask for them.

In this verse, the word dvija-deva-mantram is very important. The word mantra means “that which delivers one from the material world.” Only the dvijas (the brāhmaṇas) and the devas (the demigods) can be delivered from material existence by the instructions of the Supreme Personality of Godhead. Whatever is spoken by the Supreme Personality of Godhead is a mantra and is suitable for delivering the conditioned souls from mental speculation. The conditioned souls are engaged in a struggle for existence (manaḥ ṣaṣṭhānīndriyāṇi prakṛti-sthāni karṣati). Deliverance from this struggle constitutes the highest benefit, but unless one gets a mantra from the Supreme Personality of Godhead, deliverance is impossible. The beginning mantra is the Gāyatrī mantra. Therefore, after purification, when one is qualified to become a brāhmaṇa (dvija), he is offered the Gāyatrī mantra. Simply by chanting the Gāyatrī mantra, one can be delivered. This mantra, however, is suitable only for the brāhmaṇas and demigods. In Kali-yuga, we are all in a very difficult position, in which we need a suitable mantra that can deliver us from the dangers of this age. Therefore the Supreme Personality of Godhead, in His incarnation as Lord Caitanya, gives us the Hare Kṛṣṇa mantra.

“In this age of quarrel and hypocrisy the only means of deliverance is chanting the holy name of the Lord. There is no other way. There is no other way. There is no other way.” In His Śikṣāṣṭaka, Lord Caitanya says, paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam: “All glories to the chanting of śrī-kṛṣṇa-saṅkīrtana!” The mahā-mantra — Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare — is directly chanted by the Lord Himself, who gives us this mantra for deliverance.

We cannot invent any means to be delivered from the dangers of material existence. Here, even the demigods, such as Lord Brahmā and Lord Śiva, and the prajāpatis, such as Dakṣa, are said to be like illuminating sparks in the presence of the Supreme Lord, who is compared to a great fire. Sparks are beautiful as long as they are in the fire. Similarly, we have to remain in the association of the Supreme Personality of Godhead and always engage in devotional service, for then we shall always be brilliant and illuminating. As soon as we fall from the service of the Lord, our brilliance and illumination will immediately be extinguished, or at least stopped for some time. When we living entities, who are like sparks of the original fire, the Supreme Lord, fall into a material condition, we must take the mantra from the Supreme Personality of Godhead as it is offered by Śrī Caitanya Mahāprabhu. By chanting this Hare Kṛṣṇa mantra, we shall be delivered from all the difficulties of this material world.

One word in this verse has two readings — kālena and kāvyena. Kālena means “favored by time,” and kāvyena means “favored by Śukrācārya,” Śukrācārya being the spiritual master of the Daityas. The demons and Daityas were favored in both ways, and therefore the demigods were advised by the Supreme Lord to execute a truce for the time being, until time favored them.

A snake and a mouse were once caught in a basket. Now, since the mouse is food for the snake, this was a good opportunity for the snake. However, since both of them were caught in the basket, even if the snake ate the mouse, the snake would not be able to get out. Therefore, the snake thought it wise to make a truce with the mouse and ask the mouse to make a hole in the basket so that both of them could get out. The snake’s intention was that after the mouse made the hole, the snake would eat the mouse and escape from the basket through the hole. This is called the logic of the snake and the mouse.

It appears that when different kinds of drugs, creepers, grass and vegetables are put into this milk and the milk is churned, as milk is churned for butter, the active principles of the vegetables and drugs mix with the milk, and the result is nectar.

It appears that by the churning process many things would be generated from the Ocean of Milk, including poison, valuable gems, nectar and many beautiful women. The demigods were advised, however, not to be greedy for the gems or beautiful women, but to wait patiently for the nectar. The real purpose was to get the nectar.

Vedic etiquette enjoins: gṛhe śatrum api prāptaṁ viśvastam akutobhayam. When enemies come to their opponent’s place, they should be received in such a way that they will forget that there is animosity between the two parties. Bali Mahārāja was well conversant with the arts of peacemaking and fighting. Thus he received the demigods very well, although his commanders and captains were agitated. This kind of treatment was prevalent even during the fight between the Pāṇḍavas and the Kurus. During the day, the Pāṇḍavas and Kurus would fight with the utmost strength, and when the day was over they would go to each other’s camps as friends and be received as such. During such friendly meetings, one enemy would offer anything the other enemy wanted. That was the system.

It appears from this verse that politics, diplomacy, the propensity to cheat, and everything that we find in this world in individual and social negotiations between two parties are also present in the upper planetary systems. The demigods went to Bali Mahārāja with the proposal to manufacture nectar, and the Daityas, the demons, immediately accepted it, thinking that since the demigods were already weak, when the nectar was produced the demons would take it from them and use it for their own purposes. The demigods, of course, had similar intentions. The only difference is that the Supreme Personality of Godhead, Lord Viṣṇu, was on the side of the demigods because the demigods were His devotees, whereas the demons did not care about Lord Viṣṇu. All over the universe there are two parties — the Viṣṇu party, or God-conscious party, and the godless party. The godless party is never happy or victorious, but the God-conscious party is always happy and victorious.

The word saṁvidam is significant in this verse. The demigods and demons both agreed to stop fighting, at least for the time being, and endeavored to produce nectar. Śrīla Viśvanātha Cakravartī Ṭhākura notes in this connection:

The word saṁvit is variously used to mean “in fighting,” “in promising,” “for satisfying,” “in addressing,” “by practical action,” “indication,” and “knowledge.”

By constitution, gold is heavier than stone. Since Mandara Mountain was made of gold and was therefore heavier than stone, the demigods and demons could not properly carry it to the Ocean of Milk.

Here is proof of the omnipotence of the Supreme Personality of Godhead, who is above everyone. There are two classes of living entities — the demons and the demigods — and the Supreme Personality of Godhead is above them both. The demons believe in the “chance” theory of creation, whereas the demigods believe in creation by the hand of the Supreme Personality of Godhead. The omnipotence of the Supreme Lord is proved here, for simply with one hand He lifted Mandara Mountain, the demigods and the demons, placed them on the back of Garuḍa and brought them to the Ocean of Milk. Now, the demigods, the devotees, would immediately accept this incident, knowing that the Lord can lift anything, however heavy it might be. But although demons were also carried along with the demigods, demons, upon hearing of this incident, would say that it is mythological. But if God is all-powerful, why would it be difficult for Him to lift a mountain? Since He is floating innumerable planets with many hundreds and thousands of Mandara Mountains, why can’t He lift one of them with His hand? This is not mythology, but the difference between the believers and the faithless is that the devotees accept the incidents mentioned in the Vedic literatures to be true, whereas the demons simply argue and label all these historical incidents mythology. Demons would prefer to explain that everything happening in the cosmic manifestation takes place by chance, but demigods, or devotees, never consider anything to be chance. Rather, they know that everything is an arrangement of the Supreme Personality of Godhead. That is the difference between the demigods and the demons.

Garuḍa was asked by the Lord to leave that place because the snake Vāsuki, who was to be used as the rope for churning, could not go there in the presence of Garuḍa. Garuḍa, the carrier of Lord Viṣṇu, is not a vegetarian. He eats big snakes. Vāsuki, being a great snake, would be natural food for Garuḍa, the chief of birds. Lord Viṣṇu therefore asked Garuḍa to leave so that Vāsuki could be brought to churn the ocean with Mandara Mountain, which was to be used as the churning rod. These are the wonderful arrangements of the Supreme Personality of Godhead. Nothing takes place by accident. Carrying Mandara Mountain on the back of a bird and putting it in its right position might be difficult for anyone, whether demigod or demon, but for the Supreme Personality of Godhead everything is possible, as shown by this pastime. The Lord had no difficulty lifting the mountain with one hand, and Garuḍa, His carrier, carried all the demons and demigods together by the grace of the Supreme Lord. The Lord is known as Yogeśvara, the master of all mystic power, because of His omnipotence. If He likes, He can make anything lighter than cotton or heavier than the universe. Those who do not believe in the activities of the Lord cannot explain how things happen. Using words like “accident,” they take shelter of ideas that are unbelievable. Nothing is accidental. Everything is done by the Supreme Personality of Godhead, as the Lord Himself confirms in Bhagavad-gītā (9.10). Mayādhyakṣeṇa prakṛtiḥ sūyate sacarācaram. Whatever actions and reactions occur within the cosmic manifestation all take place under the superintendence of the Supreme Personality of Godhead. However, because the demons do not understand the potency of the Lord, when wonderful things are done, the demons think that they are accidental.
