For anyone from any religious or spiritual persuasion, if you are interested in augmenting your understanding of human psychology, spirituality, and history, the author Idries Shah I have found to be the most accurate writer in English about the Truth of our daily and esoteric existence.

His Sufi credentials are constantly challenged, however, the proof of his knowledge can be found in the direct experience with his texts.

From Learning How to Learn
(pg. 28): "It is no accident that Sufis find that they can connect most constructively with people who are well integrated into the world, as well as having higher aims, and that those adopt a sensible attitude towards society and life as generally known can usually absorb Sufi teachings very well indeed."
From The Sufis
(Introduction): The Sufis are an ancient spiritual freemasonry whose origins have never been traced or dated... Though commonly mistaken for a Moslem sect, the Sufis are at home in all religions: just as the "Free and Accepted Masons" lay before them in their Lodge whatever sacred book-whether Bible, Koran, or Torah-is accepted by the temporal State."
Please let this knowledge grow within your heart.
