this is a very good book, for those who are just beginning there inquiry into the mystics, perrenial philosophy, etc.
I pair it with Aldous Huxley’s THE PERRENIAL PHILOSOPHY, whiich is
more difficult, but has more depth. Hooper would provide a good introduction to Huxley, as well as E. UNDERHILL’s classic MYSTICISM.
Enjoy, and seek to pierce the veil, to break on through to the other side.
