I have been doing the 9 Phases Form for a good on and off for the past 2 months. After practicing every day, I have the movements in my body, and understand coordinating the breathe and the movement. Ease with the form and breath left me time and capacity to notice other things. Recently, I have been noticing that my tongue ends up somewhere between the roof of my mouth and the back side of my upper teeth. I wonder if that's where my tongue ends up because I am thinking too hard, or if there is any special significance to it. Thoughts?
