The Sages of the Talmud say: מה למעלה מה למטה מה לפנים מה לאחור "What is above? What is below? What is inside? And what is outside? For one who looks into these things --it is better if he had never been created."
It does seem that most people that go into mysticism go a little bit insane. But they remain sane enough to hide their nutty ideas of grandeur. But eventually it comes out to the surface. They can not hide it forever.
The general approach of authentic Litvak yeshivas towards this is to disavow any knowledge. The response of roshei yeshiva towards this kind of thing is "It is high things."
I myself spent a lot of time learning the Ari and the Reshash and Rav Yaakov Abuchatzeira, but at this point it seems to me I would be doing a lot better today if I had stuck with Gemara Rashi and Tosphot.
