The Magic Sack
Probert was one of the greatest psychic mediums of his time. This amazing wisdom was given by a number of different spiritual masters who all came through the author. Most channelers have one entity who comes through them, but Mark had many. Probert would fall asleep, much like Edgar Cayce, and would speak in various languages and dialects clearly, although he did not know any languages except English when conscious. His voice would change for each teacher and would never vary. Older people who knew Mark state there was no one better then, or now, for transmitting such knowledge. Teachers include Yada, Lao-Tsu, Professor Alfred Luntz, Lo Sun Yat, Arakashi, Maharaja Natcha Tramalaki, and more.
