Every form is built by an impulsive spark of life, emanated by a creator, and growing stage by stage under the law of accretion - an aspect of the law of attraction, which is the Law of Life. This law cooperates with the Law of Cause And Effect, which, as we know is the law of governing matter.
Cause, attraction or desire, accretion and effect - these four words govern the construction of any thought form. When the latter is a completed entity, it is an effect built by accretion under the power of an organised cause.
