The Bhagavad-Gita

 

I have read the Qu'ran and The Book of Mormon, but I had never read another religion's writings. So, this was interesting for me. It "has been an essential text of Hindu culture in India since the time of its composition in the first century A.D. One of the great classics of world literature, it has inspired such diverse thinkers as Henry David Thoreau, Mahatma Gandhi, and T.S. Eliot; most recently, it formed the core of Peter Brook's celebrated production of the Mahabharata (book description on Amazon.com). 

It is the discussion between Pandava prince Arjuna and his guide, Krishna, the Supreme Personality of Godhead. Arjuna brings moral dilemmas and seeks Krishna's counsel.
