Joel Goldsmith's class work in Hawaii in 1959 was devoted exclusively to reintroducing the healing principles of the Infinite Way, which are essential to establishing a foundation for mystical living. The Foundation of Mysticism provides edited transcripts of these important tape-recorded classes, which Goldsmith later referred to as the most significant material available to fully understand the principles and the practice of The Infinite Way.

Speaking about spiritual healing, Goldsmith says, "If you have an infinite, eternal, immortal God, and in the entire kingdom of God there is no evil, then, as scripture says, 'God is too pure to behold iniquity.' Certainly God wouldn't tolerate it today and then heal you of it tomorrow. That would make of God a human being, and not even a very nice one. Oh, no The reason healing is possible is this: God is, and God constitutes this universe, and God constitutes your being, which is perfect."

New students will find this classic book to be a valuable and complete introduction to the principles of the Infinite Way, while experienced students will benefit greatly from the fresh clarity with which Joel teaches the principles anew.
