A year or more ago I stumbled on a book by an American author who had spent time in India studying hatha yoga with a teacher there, this may have been in the 30's, 40's or 50's. This writer was not a household name like some of the Americans such as Indra Devi who studied there at various times. This fellow studied a pretty stringent variety of hatha. He later disappeared in India and was never seen nor heard of again. His books are now out of print, but I ordered a copy online, and never received it in the mail, and now have forgotten title and author. If this description rings a bell for someone, I'd certain appreciate hearing back with information.
