Tao means "the Way". It is a religious or philosophical tradition of Chinese origin which emphasizes living in harmony with yourself and the Tao. It accents on Wu wei (action without intention), naturalness, simplicity, spontaneity, and the Three Treasures: compassion, frugality, and humility.
Wu wei is a central concept in Taoism and Shiatsu. It means "action of non-action" or "action without intent" - it is a natural action that does not involve struggle or excessive effort. Wu wei is the cultivation of a mental state in which our actions are in alignment with the flow of life. In Shiatsu, this means that we do not force to get a result.
