Comment: It should be apparent to all that I have adopted much of the Kabballah thinking, but have only read one book on the subject. > > Which book did you read, David, if you don't mind me asking?-Endless Light, The Ancient Path of the Kabbalah, by David Aaron, 1998 paperback. He is a rabbi in Israel. the long essay makes much of the use of light, and as the first step in creation, 'let there be light'. Note that Turok in his bouncing universe uses light.
