In esoteric science, all manifestation issues from the Absolute (unity) according to the Law of Three, giving rise to the Law of Seven in a descending octave.
The esoteric Tradition also teaches that all levels of the Cosmic Ray of Creation are formed by the same laws, that man is formed on the same plan as the universe and that if we were able to reduce ourselves to the level of the microcosmos, ie a cell, we should see the Universe if we were to look up inside the body.
