Occasionally practice your Tai Chi form focusing only on your supporting 
foot or feet connecting deep into the earth as you move from posture to posture to get a sense of being grounded.
Chair Chi: Grounding
While practicing my Chair Chi exercises this morning I focused on the theme of grounding.
Grounding is the ability to stabilise yourself by allowing the Chi to flow through your legs and deeply into the ground. It’s similar to a tree stabilised by its deep and spreading roots.
