Qigong, do you practice and if so, why?

I like to practice Ling Wu Ziran Gong from Emei Linji Qigong. Ling Wu Ziran is Chen, or Zen. My favorite is the Wuji form after series of movements. In this practice,

"Qi initiates movement instead of movement following mind-intention or thought. Never allow your mind to lead Qi or force and induce movements." *

*Ling Wu Ziran Gong by Zongshi Wei Zhong Foo

What does the Qi do when the mind doesn't lead it? Thats where I need to go
