The age of gurus is passing, and in fact none too soon: granted that most gurus are harmless, there is a contingent that, as with sufism, is extremely dangerous. You simply don’t want to become involved. Raja yoga done alone can be a valuable exercise, but at this point does any of that work? And the realm of Hindutva lurks to try and annex it all into their confusion.
Once you see the victims of these gangsters and their true horrible plight with noone to rescue them, the world of yogis (and buddhas, sufis) is seen for what it is.
