I see no problem with physics-based explanations for spiritual exercises. If mind and body really are one, then the result of what some would call a spiritual or mental exercise should have at least some residual effect in the physical world that can be talked about or analyzed. Isn't that what a ki test is all about?
Hi Eric. How about spiritual-based explanations for physical exercises?
Spirit is spirit, mind is mind, body is body. They're always connected but how often are they in harmony?
Of course you can analyze the physical effect but by limiting yourself to the physical only then you may never find the real why.
Just being aware that there is a mental aspect and a spiritual aspect means that as you train and come across realizations then you can acknowledge them for what they are and gain a deeper understanding of what you are doing no?
