oldmansmoking I have read a few biographies of his, and watched some documentaries. The individual ... not my cup of tea, in my opinion he was a lunatic in search of attention. The older he got, the more nutty he became. He is definitely not a reference I would easily use when talking about esoteric topics, or at least not a positive one. Severe drug abuse, filled his teeth to seem like he is a vampire, orgies, blood rituals ... yeah, doesn't sound that sane to me. As far as writing goes, there are so many better occult/esoteric philosophers (neo-theosophical or not)contemporary to his time that it almost makes him look like a bad joke. Charles Leadbeater, Rene Guenon, Rudolf Steiner, are just a few names that come to mind ...
Mountaineer, yoga ... yes, sure, I don not contradict you, but that's not what he wanted to be remembered for. Please do not take this as disrespect towards your opinion, it's just my personal view on the topic ...
