Gandhi on the Gita, Mohandas K. Gandhi

Mahatma Gandhi's own translation of the Bhagavad Gita with his chapter by chapter explanations of the ethical principles behind the scripture. Although Gandhi wrote tons of stuff, even his Story of My Experiments with Truth does not give as concise an explanation of the basis of his own beliefs.

Another book that may be of interest you can find at this link: William Blake's The Everlasting Gospel. This is a collection based on a book that Blake himself never saw published, poems on his understanding of Jesus and his message. "Seeing this false Christ, in fury and passion / I made my voice heard all over the nation." ISBN 978-0-942208-07-8. $9.95. 68pp. "Do what you will, this life's a fiction / and is made up of contradiction."

For a very American expression of spirituality (some may contest my characterization), try this link for Walt Whitman's Leaves of Grass (original edition). Whitman broke the mold on poetry, but also on thinking about a higher dimension. ISBN 978-0-942208-08-5. $11.95.
