I did a lot of esoteric symbols for a while and created quite a number of images with them. Just like that, with no further intentions, I just enjoyed it. I learned a lot about their meanings, their history and possibly also about their effects.
But today, on November 12th, 2019, I found more information on this from Rudolf Steiner.
“For the occult, the symbols have a real meaning. A symbol that is merely an image has no meaning; only something that can become reality can pass into force. If a symbol acts on the spirit man in such a way that intuitive powers are thereby set free, then it is a real symbol. Today the Freemasons say we have symbols that mean this and that. But an occult symbol is one that takes hold of the will of man and passes over into the astral body. ”GA 93, p. 89f.
“It was necessary in these occult schools … that among the many things that had to be overcome in order to also overcome egoism, there was even this: not to speak in the ordinary words within the mysteries, within the occult schools, not to communicate with the ordinary words with which one communicates in the life of external consciousness. Because a certain kind, even if a finer one, one would like to say, higher egoism already passes over into people by using the words, thoughts and concepts that are used in external life.
All those things come into consideration that do not make a person appear as a person in general, but as a member of a certain people with all the egoisms that are peculiar to him because he,legitimately for the outer life, loves his people. For the highest general human knowledge that is to be sought behind the life of ordinary consciousness, we must not bring these higher, refined egoisms with us either.
Therefore the preparation in the occult schools was practiced in such a way that, as it were, first a general human language was created. In these occult schools it was not the language of ordinary life that was used, but a language that ACTED differently on people than any other language that was spoken here or there. It was a language that worked not through words and thoughts, but through symbols. For those who know mathematics it is readily apparent that it has general application by choosing symbols,that can be used anywhere.
By choosing such symbols, so to speak, developing upwards to have a language that speaks in symbols, one was beyond what is mixed up in our judgment, in our ordinary consciousness, of egoism, also of higher egoisms.
But then what you could represent and say was understandable only to those who had first come to know this general human language, these symbols.who first got to know this common human language, these symbols.who first got to know this common human language, these symbols.
The language consisted of symbols that one could draw, that one carried out in hand movements in the rituals, expressed in color combinations and so on. And the main thing in the secret schools was not what was proclaimed by the words, for that was only preparation, but what was said in the language of symbols, independently of ordinary human words and also independent of ordinary human thoughts.
In the most ancient times, those who belonged to the Mysteries as initiates regarded it as the strictest obligation not to reveal anything to the outside world about the general language of the Mysteries, about the general symbols, because man, if he had got to know the symbols and had been astute enough, would have been unprepared for them Means of occult knowledge could have come.The creation of the symbols was the means of speaking a common human language. The secrecy of the symbols was the means of preventing what was given to them through this language from reaching immature people.
The creation of the symbols also has the other purpose and sense of creating means in which one can express what cannot be expressed with ordinary human words and concepts. Occult knowledge is one that is obtained outside the physical body. It is still impossible at all for the beginning of occult knowledge to express them with the means that have been attained through the physical body ”. GA 137, p. 17ff
