Very powerful Yogananda quote?

Mind, which controls all the cells, is the basic factor. When a man attains full control of mind, his bodily cells and parts may be replaces or changed as often as desired , and it will. For example, he could, just by a thought, cause the bodily atoms to change and bring into being a whole new set of teeth. There is complete control of matter when one is advanced spiritually. -Yogananda. What do you think about this quote. I think it's quite amazing. that sentence is from Yogananda's How You Can Talk With God book.
