“Bhagavad-Gita” means the song of God. It is the conversation between a man called Arjuna, and God Himself in the human form, Lord Krishna. It is the only scripture on the planet that can be called the word of God in person. This conversation took place 5000 years ago in Kurukshetra, India. The Bhagavad-Gita is based on questions raised from man (Arjuna) and answers given by God (Lord Krishna).
