Thought creates; the extent of thought in space is unencompassable. Thus, many experiments serve only partially to broaden the understanding of the power of thought. People are astonished at the inexplicable character of clairvoyance pertaining to the future, seldom realizing that the fire of thought kindles and constructs an image of the future. Thoughts of various times and content construct subtle worlds which are accessible to clairvoyance. Among many causes of evolution, thought-creativeness has a primary significance. Therefore I so often repeat about the quality of thought.
