THE SPIRITUAL WORK OF THE STUDENT "Know thyself"... All science, all wisdom is there: in knowing ourselves, in rediscovering ourselves, the union of the lower with the higher Self. The symbol of the Mystic who has managed to meet himself is the serpent biting its tail (the ouroboros). The serpent represents a straight line, or a broken one, and the line is nevertheless limited. The serpent biting its tail becomes a circle, and the circle is the infinite, the unlimited, it is eternity. The person who has managed to realize the symbol of the circle enters a world where there are no longer any limits, where there is no longer any separation between the above and the below, because all the powers, riches, and virtues that the true Self possesses are diffused into the small self. The small and the great are now united, and the person becomes a deity." Omraam Mikhael Aivanhov
