Once during the Qing dynasty in China the Emperor and his courtiers decided to make a sport out of all the outrageous claims martial artist were making. They had many martial artists brought one by one to the palace and asked them to perform many feats, after which they were usually put to death.
The Emperor heard about a bagua master who people claimed could move any stone. So the Emperor had a huge stone brought into the courtyard using long levers and pulleys. He then had the famed martial artist brought to the palace. Upon seeing the challenge he asked to be given 24 hours and some torches to see by. Amused, the Emperor granted the request. The martial artist began crawling all over the of the stone, looking and feeling everywhere. 24 hours later the Emperor and his courtiers returned and demanded to see the stone moved. The martial artist then put one finger on one particular spot and using just that finger succeeded in pushing the huge stone all around the courtyard. The Emperor and his courtiers were so impressed that they granted him his life.
It seems that even stones have acupuncture meridians.
It is said that a bagua practitioner who has reached the height of mastery can step on a solid cobble stone and turn it to dust. I imagine that such steps are extremely light.
The adepts experience of the world is recreated in each step or gesture we make. Qi gong practitioners don't just re-learn how to walk, we are continuously re-learning how to walk. We are demonstrating true openness to the possibilities. The fruit of practice is that walking itself becomes unconditioned.
