“The Tibetan Book of the Dead is ostensibly a book describing the experiences to be expected at the moment of death, during an intermediate phase lasting forty-nine (seven times seven) days, and during rebirth into another bodily frame. This however is merely the exoteric framework which the Tibetan Buddhists used to cloak their mystical teachings. … The esoteric meaning, as it has been interpreted in this manual, is that it is death and rebirth of the ego that is described, not of the body. Lama Govinda indicates this clearly in his introduction when he writes: "It is a book for the living as well as the dying." The book's esoteric meaning is often concealed beneath many layers of symbolism. It was not intended for general reading. It was designed to be understood only by one who was to be initiated personally by a guru into the Buddhist mystical doctrines, into the pre-mortem-death-rebirth experience. These doctrines have been kept a closely guarded secret for many centuries, for fear that naive or careless application would do harm.”

... There are residue dreams which are an extension of our waking life. Then there are what Carl Jung calls "big dreams" and my dream about the Tibetan Book of the Dead was one of those big dreams. One of those can change your life. It can change it for awhile or forever. Those dreams are in the same local time domain as when we have an experience of Holy Spirit.

There is a wide-spread, and withal a popular, idea that there is no such thing as an occult teaching in connection with Christianity, and that "The Mysteries," whether Lesser or Greater, were a purely Pagan institution. The very name of "The Mysteries of Jesus," so familiar in the ears of the Christians of the first centuries, would come with a shock of surprise on those of their modern successors, and, if spoken as denoting a special and definite institution in the Early Church, would cause a smile of incredulity.
