You know, its interesting, I have seen Vladimir Vasiliev's psychic tape. It has been awhile but I have seen it. And if not the first thing he says, it may be the second or third thing he says, but he says early on in the tape, before he actually shows anything, that the training they do in psychic work should never be seen as a replacement for the physical training in systema.
Never should you think you can get away without training the physical. Never.
Now I have no idea if the Systema stuff is for real or not. He gives one little training exercise for people to try, and I have tried it. It seems to me you would really have to put in some long hours to develop it to any kind of usefullness.
But my point is that one of the first things he says is that it should never be seen as a replacement for the physical stuff they do. IMHO if you do that you are living in La-La-Land.
Its like a continuum line. On the left, lets say, is the hardest punch or kick you can possibly throw. Then as you get into progressively more softer moves like parries you are at the middle of the line with sensitivity exercises like push hands or hubud lubud. Then on the farthest to the right on the continuum would be to go into this kind of work if you want and if you can find a teacher.
But to engage in the fantasy you can turn your back on the whole line in favor of one piece?
La-La-Land.
