Krishna lifting Govardhan hill
Every year, Nanda maharaja and the cowherd people performed ceremonoes for Indra, the rain God. Since Govardhan hill provide the cows fresh grass, Krishna advised them to start worshipping Govardhan hill instead. When they started celebrating and performed ceremonies for Govardhan hill, Indra became angry and he ordered the clouds to destroy Gokul by causing heavy rains.
The whole village was struck by heavy rains and was flooded. Everyone, including the cows and calves, prayed to Krishna to protect them. Krishna lifted Govardhan hill using his left little finger, just like an umbrella.
Everybody took shelter under the hill for seven days. Indra was wonder struck by this feat by Krishna and stopped the rain felt sorry. The inhabitants of Gokul returned home happily.
