The Advent of Srimad Bhagavad-gita

This is the annirversary day commemorating the day that Srimad Bhagavad Gita was spoken by Lord Sri Krishna to His dearmost devotee Arjuna at the place now known as Jyotisar Tirtha amid the waring families of the Kurus and the Pandavas at Kurukshetra. If one wishes one can still go and visit that place and see the monument erected there with Krishna as Parthasarati (the chariot driver) and Arjuna the warrior on their chariot. It is claimed by the ashram who maintain the shrine that the tree that is next to Them is a continum growth of the original tree witness that was there at the actual day of speaking. Traditionally devotees come to Kurukshetra (Dharmakshetra) and recite Bhagavad Gita from early morning until the next morning, perform arati to Bhagavad Gita and to Krishna and Arjuna upon the chariot, offer lamps 'deep daan' at BrahmaSarovar, shloka recitals, shobha yatras and seminars on the significance of the Gita today. Devotees who cannot get to Jyotisar Tirtha remember the blessed event by reciting Bhagavad Gita, performing Bhagavad Gita ahuti of each verse or selected chapters into the sacred fire, and discussing the subject matter of Bhagavad Gita in the association of devotees. Distribution of Bhagavad Gitas' on this day is also a very auspicious activity to perform.
