The Sepher Bahir

The Sepher Bahir is one of the foremost works of all mystic Judaism, an important work of Kabbalah in which commentaries on sounds, words, and stories are presented in a somewhat choppy form (for it was a compiled manuscript, not a primordial single work.) The work is ascribed to a mystic rabbi named Nehunya circa the first century. It refers as well to another mystic work- the famous Sepher Yetzirah, equally as renowned for its spiritual lore.
