Govardhan-Puja is also performed in the North on this day. Govardhan is a small hillock in Braj, near Mathura and on this day of Diwali people of Punjab, Haryana, Uttar Pradesh and Bihar build cowdung, hillocks, decorate them with flowers and then worship them. This festival is in commemoration of the lifting of Mount Govardhan by Krishna. As per Vishnu-Puran the people of Gokul used to celebrate a festival in honor of Lord Indra and worshiped him after the end of every monsoon season but one particular year the young Krishna stopped them from offering prayers to Lord Indra who in terrific anger sent a deluge to submerge Gokul.
People were afraid that the downpour was a result of their neglect of Indra. But Krishna assured them that no harm would befall them. He lifted Mount Govardhan with his little finger and sheltered men and beasts from the rain. This gave him the epithet Govardhandhari. After this, Indra accepted the supremacy of Krishna.
