The sacrifice known as Govardhana-pūjā is observed in the Kṛṣṇa consciousness movement. Lord Caitanya has recommended that since Kṛṣṇa is worshipable, so His land—Vṛndāvana and Govardhana Hill—is also worshipable. To confirm this statement, Lord Kṛṣṇa said that Govardhana-pūjā is as good as worship of Him. From that day, Govardhana-pūjā has been going on and is known as Annakūṭa. In all the temples of Vṛndāvana or outside of Vṛndāvana, huge quantities of food are prepared in this ceremony and are very sumptuously distributed to the general population. Sometimes the food is thrown to the crowds, and they enjoy collecting it off the ground. From this we can understand that prasādam offered to Kṛṣṇa never becomes polluted or contaminated, even if it is thrown on the ground. The people therefore collect and eat it with great satisfaction.
(Krsna Book).

The Supreme Personality of Godhead, Kṛṣṇa, therefore advised the cowherd men to stop the Indra-yajña and begin the Govardhana-pūjā in order to chastise Indra, who was very much puffed up at being the supreme controller of the heavenly planets. The honest and simple cowherd men, headed by Nanda Mahārāja, accepted Kṛṣṇa's proposal and executed in detail everything He advised. They performed Govardhana worship and circumambulation of the hill. (Following the inauguration of Govardhana-pūjā, people in Vṛndāvana still dress nicely and assemble near Govardhana Hill to offer worship and circumambulate the hill, leading their cows all around.) According to the instruction of Lord Kṛṣṇa, Nanda Mahārāja and the cowherd men called in learned brāhmaṇas and began to worship Govardhana Hill by chanting Vedic hymns and offering prasādam. The inhabitants of Vṛndāvana assembled together, decorated their cows and gave them grass. Keeping the cows in front, they began to circumambulate Govardhana Hill. The gopīs dressed themselves very luxuriantly and sat in bull-driven carts, chanting the glories of Kṛṣṇa's pastimes. The brāhmaṇas, assembled there to act as priests for Govardhana-pūjā, offered their blessings to the cowherd men and their wives, the gopīs.
(Krsna Book).

The form of Kṛṣṇa who began to eat the offerings was separately constituted, and Kṛṣṇa Himself, along with the other inhabitants of Vṛndāvana, offered obeisances to the Deity as well as Govardhana Hill. In offering obeisances to the huge form of Kṛṣṇa and Govardhana Hill, Kṛṣṇa declared, "Just see how Govardhana Hill has assumed this huge form and is favoring us by accepting all the offerings!" Kṛṣṇa also declared at that meeting, "One who neglects the worship of Govardhana-pūjā, as I am personally conducting it, will not be happy. There are many snakes on Govardhana Hill, and persons neglecting the prescribed duty of Govardhana-pūjā will be bitten by these snakes and killed. In order to assure the good fortune of the cows and themselves, all people of Vṛndāvana near Govardhana must worship the hill, as prescribed by Me."
Thus performing the Govardhana-pūjā sacrifice, all the inhabitants of Vṛndāvana followed the instructions of Kṛṣṇa, the son of Vasudeva, and afterwards they returned to their respective homes.

But Kṛṣṇa replied, "My dear father, don't delay. The sacrifice you propose for Govardhana and the local brāhmaṇas will take much time. Better take the arrangement and paraphernalia you have already made for the Indra-yajña and immediately engage them to satisfy Govardhana Hill and the local brāhmaṇas." Mahārāja Nanda finally relented. The cowherd men then inquired from Kṛṣṇa how He wanted the yajña performed, and Kṛṣṇa gave them the following directions. "Prepare very nice foods of all descriptions from the grain and ghee collected for the yajña. Prepare rice, dhal, then halavā, pakorā, purī and all kinds of milk preparations, such as sweet rice, rabrī, sweetballs, sandeśa, rasagullā and laḍḍu, and invite the learned brāhmaṇas who can chant the Vedic hymns and offer oblations to the fire. The brāhmaṇas should be given all kinds of grain in charity. Then decorate all the cows and feed them well. After performing this, give money in charity to the brāhmaṇas. As far as the lower animals are concerned, such as the dogs, and the lower grades of people, such as the caṇḍālas, or the fifth class of men, who are considered untouchable, they also may be given sumptuous prasādam. After nice grasses have been given to the cows, the sacrifice known as Govardhana-pūjā may immediately begin. This sacrifice will very much satisfy Me."
