The following books set forth the basic tenets of their respective religions:

Bhagavad Gita: part of the epic poem Mahabharata, this Sanskrit dialog between Krishna and Prince Arjuna poetically describes a path to spiritual wisdom and unity with God. Action, devotion, and knowledge guide on this path.

Torah: the books of Moses (also known as the Pentateuch); for Chistians, the first five books of the Old Testament: Genesis, Exodus, Leviticus, Numbers, Deuteronomy. These describe the origin of the world, the covenant between God and the people of Israel, the Exodus from Egypt and return to the Promised Land, and rules for religious and social behavior. Together with the books labeled Prophets and Writings, they make up the entire Old Testament. The controversy among Jews, Roman Catholics, Eastern Christians, and Protestants about the acceptance of some books, the order of books, and translations reflect the different perspectives adopted within these religions.

New Testament: the Christian addition to the Bible comprises 27 books. They contain sayings attributed to Jesus, his life story (death and resurrection included), the writings of the apostles, rules for conversion and baptism, and the Apocalypse (the end of this world and the beginning of a new one).

Koran (al Qur'an): the holy book of the Moslems, is composed of 114 chapters (called suras). Belief in Allah, descriptions of rules for religious and social life, calls to moral life, and vivid descriptions of hell make up most of the text. According to Moslem tradition, Mohammed ascended the mount an illiterate. He came down with the Koran, which Allah had taught him to write.

I-Ching: attributed to Confucius, composed of five books, containing a history of his native district, a system for divining the future (Book of Changes), a description of ceremonies and the ideal government (Book of Rites), and a collection of poetry. In their unity, all these books affirm principles of cooperation, reciprocal respect, and describe etiquette and ritual rules.
