Hilton Hotema wrote numerous books on ancient wisdom, alternative health, and hidden knowledge. He became a vegetarian at the 9 and continued with an extremely healthy lifestyle until his death at age 92 in 1970. His books on ancient wisdom and suppressed knowledge are very well researched and often rub against the accepted teachings of mainstream religious institutions. This has resulted in an interesting underground sub-culture that seeks out his books and is going strong to this very day.
