On this day, 5000 years ago, on the battlefield of Kuruksetra, the Supreme Lord delivered the most confidential and topmost knowledge of devotional service to His lotus feet in the form of the Bhagavad-gita to His dearmost devotee Arjuna, and to humanity at large, in order to help all devotees understand the purpose of life and the way to surrender to Him.

A gita-yajna is performed at Mayapur while devotees recite verses from Bhagavad-gita. A Gita Book Marathon also takes place and devotees take part in actively distributing Srila Prabhupada’s Bhagavad-gita to visitors. Usually devotees fast till noon, go to the Ganga for Ganga-puja and bath in her holy waters and a Harinama-sankirtana is held in the evening.
