I used to over intellectualise matters concerning tai chi.
Now I don't.
It doesn't help. It's a façade.
As an example, part of my training in Sun style is to stand in San Ti posture. When I was first introduced to it, I rushed to my books and researched it, looking at the various visualisations and what I could be focusing on. And there is a lot!
I discussed this with my teacher, a disciple of the late Sun Jian Yun.
" Just stand, don't think about anything" was the advice.
So I did. I moved away from my previous practises which involved focusing on different points and connecting them.
Over time I have found a clarity in the Sun style tai chi that I hadn't experienced before. When I practise the simple movements there is a wonderful directness about them. I am energised like never before.
This is of course just my personal experience. But I have found that overthinking doesn't help. Just keep it simple and experience directly. Try it.
