It's the same as Tai Chi. I suggest to rest on God, not your body. It's even more relaxing and infinitely safer to put your trust in God. This was a suggestion, the choice is yours. But especially if you are a Christian, you should be aware of what your choice involves.
Any physical healing is offset by a transference of the physical malady to a spiritual malady.
Tai Chi and Yoga are not just a physical practice. Yoga is a mental as well as a physical practice. Yoga and Tai Chi are parts of Hinduism. The realisation of Self meaning that one believes he is God, the ultimate deception and the earliest one. It's the same deception of Adam and Eve in the Garden of Eden, when they thought that the apple could make them like God.
