Taoism is quite clear when it comes to mastery.
You must address your own concerns before attempting to control or manipulate other things.
Scholars of the tao question the very notion of mastery.

Neigong is ‘internal work’; a unique process of moving the whole body as one unit.
Rather than rely on tensed muscles, neigong teaches the student to remain physically relaxed and composed at all times, and move every body part together.
This is not as easy as it sounds.

Everything is changed by neigong. Every qigong exercise, form posture and movement is altered.
The body literally re-grows from the inside out.

Sifu Waller had a kind of internal arts open-house in the late 80's/early 90's, with students from all kinds of martial arts calling at his house. He met them at work, in classes, in bookshops, at workshops. They came and they trained. Shaun Ullah converted his living room into a dojo of-sorts, complete with wallbag, heavy bag and weaponry. This was a time of great sharing and discovery, with Sifu Waller at the centre yet taking no credit.

Muscles serve two main functions:

1. They help to hold the skeleton upright
2. They move the bones

If you encounter resistance but continue to push against growing pressure, which of these functions is being served?
