In the 1980's I was in the Siddha Yoga movement and on speaking terms with some of the swamis. One story of the dozens I heard stuck with me, and Shirley and I, then known as Siddheshwari and Vaman respectively, have found it very cogent as the years go by.
Muktananda had a big ashram in the Catskills and it was there that one of the swamis had a most disturbing dream. He dreamt that his leg was damaged very severely, beyond hope of repair. The dream was so vivid and real that he woke up sweating and went down for his swami breakfast in a disturbed state.
