“He named man ‘insan’ (from the Arabic word…whose root implies intimacy and friendship) because of the possibility of intimacy between him and the rest of creation. He also placed within him…an inner reality and an outward form which… enables him to act in both the earthly and spiritual worlds. His inner reality is the Greater Spirit… the Universal Soul is his treasurer and bondsman; Universal nature is his agent and the head of the natural forces.”
(Sayyid Hayder Amuli, “Inner Secrets of the Path”)
