Spiral The path of a point (generally plane) which moves round an axis while continually approaching it or receding from it; also often used for a helix, which is generated by compounding a circular motion with one in a straight line. The spiral form is an apt illustration of the course of evolution, which brings motion round towards the same point, yet without repetition.
The serpent, and the figures 8 and , denoting the ogdoad and infinity, stand for spiral cyclic motion. The course of fohat in space is spiral, and spirit descends into matter in spiral courses. Repeating the process by which a helix is derived form a circle produces a vortex. The complicated spirals of cosmic evolution bring the motion back to the point from which it started at the birth of a great cosmic age.
