basic body movement (Tai no sabaki), hand movement, foot movement, centre line focus and alignment of feet, hips, body and arms, proper breathing, building up and the use of Ki, extension, posture, awareness, focus
I have a few questions regarding your post.
Do you consider each item in the above-quoted list to be basic? Some of them seem pretty advanced to me. For example, the concept of "building up and the use of Ki."
What are some examples of flashy techniques that you think should not be attempted before one has a sufficient grounding in the basics?
Can you also explain which types of spiritual experiences that one may think he or she has had that would actually be false if not built upon a sufficiently strong foundation of basics?
