the only teacher of the Fourth Way

But there is a Fourth Way. This is also called Yogism, but it is different because this kind of yogi has a secret by "heredity" - initiate secrets. By this way, with a teacher, a man with the possibility can do the work in six months and then be his own teacher.
I am the representative of the Fourth Way. And I have no concurrent (rival). For instance, ordinary yogis who do not know these secrets lie for three hours a day to learn how to use air. With my secret short-cuts they could do this in five minutes - in fact, like magic, drink the elements they need from air out of a glass.
