Hi there!
I'm sorry for my English - it's not my native language so if I'm being rude - please, forgive me in advance - it's not intended.
I'm 48y old kendoka with some findings on the different ways, mostly in Budo and Kastaneda's way of power.
From my experience, the proper technique works on proper basics, not some beliefs. So "basics" are almost always felt in the physical body. So what helped me on my way is - you feel it - then it's real.
Here, on this forum, I found helpful thoughts and knowledge about inner energy. I think it's time to say "Thanks" and "Hi" to everyone from this forum.
