Now a "myth" is by no means what most people imagine it to be--a mere fanciful story erected on a basis of fact, or even altogether apart from fact. A myth is far truer than a history, for a history only gives a story of the shadows, whereas a myth gives a story of the substances that cast the shadows. As above so below; and _first_ above and _then_ below. There are certain great principles according to which our system is built; there are certain laws by which these principles are worked out in detail; there are certain Beings who embody the principles and whose activities are the laws; there are hosts of inferior beings who act as vehicles for these activities, as agents, as instruments; there are the Egos of men intermingled with all these, performing their share of the great kosmic drama. These multifarious workers in the invisible worlds cast their shadows on physical matter, and these shadows are "things"--the bodies, the objects, that make up the physical universe. These shadows give but a poor idea of the objects that cast them, just as what we call shadows down here give but a poor idea of the objects that cast them; they are mere outlines, with blank darkness in lieu of details, and have only length and breadth, no depth. History is an account, very imperfect and often distorted, of the dance of these shadows in the shadow-world of physical matter. Anyone who has seen a clever Shadow-Play, and has compared what goes on behind the screen on which the shadows are cast with the movements of the shadows on the screen, may have a vivid idea of the illusory nature of the shadow-actions, and may draw therefrom several not misleading analogies.[178] Myth is an account of the movements of those who cast the shadows; and the language in which the account is given is what is called the language of symbols. Just as here we have words which stand for things--as the word "table" is a symbol for a recognised article of a certain kind--so do symbols stand for objects on higher planes. They are a pictorial alphabet, used by all myth-writers, and each has its recognised meaning. A symbol is used to signify a certain object just as words are used down here to distinguish one thing from another, and so a knowledge of symbols is necessary for the reading of a myth. For the original tellers of great myths are ever Initiates, who are accustomed to use the symbolic language, and who, of course, use symbols in their fixed and accepted meanings.
