Why is LOO the purest spiritual source?

[Stranger]

I took the advice of Ra and pursued Tarot, Astrology, and Kabbalah. One finds the same information repeated endlessly back into the mists of time. The Ra material is just speaking your language is my guess . For example G.I. Gurdjieff's writings teach the same concepts as well, difficult to read, but deep study of Gurdjieff will bring you to the same understanding as the Ra books with some additional very real observations of the real world that Ra dare not make. Ra's self imposed rules not to infringe on free will leave the teachings very open and acceptable to almost everyone but at the same time lack that finer instruction supplied by a teacher that lives in the same world we do.

If I may suggest, master a single system. Be it astrology, I-ching, tarot, kabbalah, which ever grabs your eye there are schools left that teach still. Then the Ra works will really open up  for you these other fields. The Ra material is like the theoretical basis for these studies not another way of study.

Kenney, what are the first 1-3 books you would recommend for someone new to Gurdjieff and NOT put off by the difficulty in reading you mentioned?
