Personally, I went more for The Five Books of Moses and Talmud. But that was simply because I had and have an inherent love of Torah. [This was something I really did not get from my Reform Synagogue. It was more a combination of the influence of my wonderful amazing parents and also a great love of philosophy.] I was not expecting any great revelation of light or Divine experiences.
But as a logical step after doing a certain amount of Talmud at the Mir in NY I got involved in the kabalah of Isaac Luria and went to Israel.
But there is at any rate a good lesson for people that are interested in true spirituality. Apparently from what I can tell the books of the Ari [Isaac Luria] and being in Israel are a remarkable help in this direction.
But one shouldn't go into this expecting magical powers. I have seen many of the Kabalists in Israel and for some reason it does seem to me that most of them got caught up in the phantom zone [the intermediate zone in the terminology of a Hindu mystic]
