Yep 💯. I also do a regular sitting practice - it works! Weird but true.

So what is Tai Chi anyway ? 🤔 (Taijiquan) 太極拳

> Two mental elements that Tai Chi cultivates are ‘song’ (release or letting go) and ‘ting’ (listening skill) as one progressively learns to absorb their awareness deeper into the body. This aspect of the art can be deepened through seated meditation practice or standing postures ‘zhan zhuang’ . 

I've been sitting daily for a year now,  and can confirm, based on the feedback I receive from my pushing hands buddies.
