Few years back during Srila Prabhupada Book Distribution Marathon,
a young engineering student came to the book stall and inquired,
"What does Bhagavad Gita teach me about life ?"
(I asked this question to a devotee, he told me tell him Krishna is the Supreme Personality of Godhead.)
But still I need to know for sure which slokas in Bhagavad Gita tell us about life definitely ?
