"Between the age of eighteen and twenty I had attained a conscious and constant union with the divine Presence and … I had done it all alone, with absolutely nobody to help me, not even books, you understand! When I found one — I had in my hands a little later Vivekananda's Raja Yoga — it seemed to me so wonderful a thing, you see, that someone could explain something to me! This made me gain in a few months what would have perhaps taken me years to do."
