My book doesn't get into the specifics of internal training (well the last chapter tells how to become Osensei in 16 easy lessons, but I suggest psychedelic mushrooms among the training tools, so I don't know how much I can be trusted . . .).
Is there actually a book that does
explain the specifics of internal training? Apart from trying mushrooms...
Where explained how to achieve internal strength, how to use it, etc...
In other words, is there anyone here on the forum who has experienced internal power and can do some tricks with it? And can learn how to achieve that to others here on the forum?
I guess no...
