My form usually consists of paying attention to quite a few points and working on them for a week or more. This morning's practice my attention happened to be on my feet. The foot is neither the beginning nor the end but it starts the momentum the rest of the body follows. Each step as I shift into the substantial foot, I am feeling the Chi travel through my body. It starts below the ground up through the bottom of my substantial foot and passes through my body and out to infinity. Then new chi energy travels back down through my head, through my body and back through the substantial foot deep into the earth. Each movement flowing from one to the next as smoothly as possible.
After years of study, paying attention to posture, alignment, breathing, etc. the body has learned and knows what to do.
Allow the chi to flow without thinking.
