Gundica marjana means cleaning of the temple Gundica, which is non-different to Vrindavan. On the day prior to the Ratha yatra festival, the temple is cleansed and decorated nicely to welcome the Lord of the Universe the next day. This practice has been going on in Puri since the time of Chaitanya Mahaprabhu. The Chaitanya – Bhagavata beautifully describes how Sri Chaitanya Mahaprabhu cleansed the temple along with his devotees. Even today in Puri this festival is observed. Many devotees come together and sweep and wash the temple.
