“Symbolism is the language of the Mysteries; in fact it is the language not only of mysticism and philosophy but of all Nature, for every law and power active in universal procedures is manifested to the limited sense perceptions of man through the medium of symbol. Every form existing in the diversified sphere of being is symbolic of the divine activity by which it is produced. By symbols men have ever sought to communicate to each other those thoughts which transcend the limitations of language. … In a single figure a symbol may both reveal and conceal, for to the wise the subject of the symbol is obvious, while to the ignorant the figure remains inscrutable.” ~Manly P. Hall
Even earlier are the many cave drawings around the world which were almost certainly intended to express some meaning and not just wall decoration. And virtually all religions, churches, mystery schools, and spiritual schools use symbols in their teachings.
Scientists say that our mind does not actually understand modern language at all. When you hear the word “duck” your brain has to convert the word into an image of a duck before it makes any sense.
In spiritual studies and spiritual growth, all great spiritual teachers and spiritual schools use symbols and images as aids to teaching and awakening the spirit and soul. The soul does not understand words at all and, unlike the brain, cannot convert the word to an appropriate symbol or image so it can understand. The language of the soul is symbols, period. Not words, not emotions, symbols.
Most Christians are totally unaware that the cross symbol, not to be confused with a crucifix, was used as a symbol for God long before Jesus was born. I think I read somewhere that this simple cross in a circle is the earliest known symbol for God. The much more complex cross symbol we use in Cosolargy has the same basic meaning, but also means a lot more. More than I can go into in this article.
The early Greek philosopher, spiritual teacher, and mathematician Pythagoras didn’t insist all of his students understand geometry because it was a cool form of math. He understood that even these simple geometric shapes have meaning to the spirit and soul, as do the more complex ones.
The cross, in various forms, is probably the most powerful symbol to aid in spiritual development and all spiritual students should look at a version of this symbol regularly.
