The individual souls are seen as units of consciousness (Monads) that are intrinsic parts of a universal oversoul, just as different sparks are parts of a fire. These Monads undergo a process of evolution where consciousness unfolds and matter develops. This evolution is not random, but informed by intelligence and with a purpose. Evolution follows distinct paths in accord with certain immutable laws, aspects of which are perceivable on the physical level. One such law is the law of periodicity and cyclicity; another is the law of karma or cause and effect.
