During Dwapara Yuga, Lord Krishna convinced the cowherd men to
worship Govardhana, instead of doing a sacrifice to please Lord
Indra,the king of heaven, who is in charge of the rain. Krishna
told the cowherd men that Govardhana Hill was supplying so many
necessities and should be worshiped instead.
His reasons for discouraging the sacrificed performed to please
Indra were twofold. First, as stated in the Bhagavad-gita there
is no need to worship the demigods for any material advancement;
all results derived from worshipping the demigods are temporary.
Secondly, whatever temporary result one derives is actually granted
by the permission of the Supreme Personality of Godhead.
Nanda Maharaja and the cowherd men called in learned brahmanas
and began to worship Govardhana Hill by chanting Vedic hymns and
offering prasadam. The inhabitants of Vrindavana dressed up themselves
nicely and decorated their cows, gopis dressed up luxuriantly
sat in bull-driven carts, chanting the glories of Krishna’s pastimes.
The brahmanas offered their blessings to cowherd men, their wives
and the gopis. In order to convince the devotees that Govardhana
Hill and Krishna himself was identical he assumed a great transcedental
form and declared himself as Govardhana Hill. Krishna began to
eat all the food offered there. The identity of Krishna and Govardhana
Hill is still honoured, and devotees take rocks from Govardhana
Hill and worship them as Lord Krishna.
After the cowherd men worshiped Govardhana Hill, Lord Indra became
angry that he was not worshiped. He sent torrents of rain upon
Vrindavana. The residents approached Krishna for help. Krishna
then lifted Govardhana Hill and held it over the residents of
Vrindavana like an umbrella.
"The inhabitants lived there with their animals for one week without
being disturbed by hunger, thirst or any other discomforts. Krishna
holded the mountain with the little finger of left hand. Seeing
extraordinary mystic power of Krishna, Indra, was thunderstruck
and baffled in his determination. He immediately called for all
the clouds and asked them to desist."
Indra came along with a Surabhi cow and offered prayers to Lord
Krishna and then worshipped him.
Lord Caitanya has recommended that since Krishna is worshipable,
so His Land Vrindavana and Govardhana Hill, are also worshipable.
Govardhana puja has been going on since then and is known as Annakuta.
In all the temples of Vrindavana huge quantities of food are prepared
in this ceremony and are distributed to general public.
