In few places, Goverdhan puja, also known as Godhan puja is
performed on the last day of Diwali celebrations. Observed on the fifth
day, Goverdhan puja is an occasion to worship Lord Krishna. According to
Vishnu-Puran, the people of Gokul commemorated a festival in honour of
Lord Indra and worshiped him after the end of monsoon season every year.
In his young years, Lord Krishna once prohibited the people from
offering prayers to Lord Indra. Angered Lord Indra sent a torrent to
sink Gokul. Lord Krishna lifted the mountain and held it as an umbrella
for the people and saved them.
