Yoga is a natural science. That is something to comprehend. Yoga is a physical science, not some obscure, imaginative thing that people just do. While yoga is relatively new to the West, it is not a newly developed discipline. It has been intensively studied and practiced in numerous countries over several centuries. Yoga is an applied science, a methodical assemblage of laws which are used to bring about a determinate ending. It utilizes the laws of psychology relevant to the evolvement of man’s consciousness on every plane, in every world applying them rationally to meet specific needs.
