Bhagavad Gita
Translated by A. Mahadeva Sastri - 1901

The Bhagavad Gita (Song of the Lord) is a Hindu text from about the 5th Century BC, in the form of a dialog between Prince Arjuna and his guide and charioteer Lord Krishna.  It is a beautiful scripture, and is one of my favorite spiritual documents.  It is a must read for anyone interested in Eastern Spirituality and Hinduism, but the lessons are universal.
