Some practiioners may experience spontaneous motion. What is it?
Partly it is because practitioners have not freed their bodies to a certain extent or in their mind there still have some stray ideas keeping arising and deceasing. Some people may claim it is the sign that they obtained some special power. But actually, it clearly demonstrates the practitioners have not fallen into deep stillness for further advancement. So, please cleanse the heart-mind further more if there arises such sign.
