from Sri Nabadwip Dham Mahatmya:
Prabhu walked with the devotees to the village of Gadigacha.
When He arrived there, He spoke with a smile: "This place
is called Godrumadwip. Surabhi, the desire-cow of Indra, resides
here eternally. When Indra, the king of demigods and lord
of rain, was overwhelmed with illusion and pride, he flooded
Gokula with rain. At that time Sri Krishna lifted Govardhan
Hill and protected Gokula. His pride crushed, Indra recognised
Krishna as the Supreme Lord and fell at His lotus feet to
beg forgiveness. Sri Krishna, the son of Nanda, being an ocean
of mercy, forgave Indra, but Indra continued to be fearful
of the sin he had committed.
"Approaching Surabhi, he said, 'Because I could not understand
Krishna's Pastimes I committed a great offense. I have heard
that in the Kali-yuga, Krishna, the son of Maharaj Nanda,
will perform wonderful Pastimes in Nabadwip. But I hesitate
to approach Him for fear of again falling into illusion and
offending Him. As you are a surabhi, a desire-cow,
you know everything. Kindly help me solve this dilemma."
