Snake,
I have not seen this thread until now, so perhaps a little late, but, yes... I was introduced to some books of Barry Long after having attended a workshop with Bernie Prior, who talkes very much about the same thing as Barry, but in a more modest way.
Barry is brilliant in some areas, but unfortunately he is not choosing the most neutral words to express his message. His way of expressing himself is rather old-fashioned and filled with morally tainted words. I think this disturbs many people, especially men, since they get it the most.
But if one can oversee with his bad taste in choice of words, his mistakes of falling into a judgemental tone, he has an important message. His teachings have helped me tremendously in my relationship. Our spiritual insights have been coming faster and faster after understanding more and more about his message.
In essence, it is what Yogani says in his Tantra-book, although Barry has gone deeper into the mind-psychology of how egos try to avoid transformation into TRUTH and LOVE.
