Agnosia: State of not having insight or Gnosis.

Alchemy: Early chemistry concerned with the search for the philosopher’s stone, a substance believed to turn base metals into gold. Also the quest for eternal life, by the use of alchemical and human transmutation. The art of alchemy can be traced back to 100-150 B.C. in China, before the practice of rejuvination and eternal life appeared in the west. The great Wei Po-Yang (100-50 A.D.), is said
to have discovered ‘true gold medicine.’ (See; Transubstantiation. See; ”
The History of Magic and the Occult,” Seligmann, Gramercy, 1997. pg. 95. See also; ”The Steinerbooks Dictionary of the Psychic, Mystic, and Occult,” Rudolf Steiner, 1973. pg. 15.)

Despite the insistence of historians of science, alchemy was never, except in its degenerate aspects, a primitive chemistry. It was a “sacramental” science in which material phenomena were not autonomous, but represented only the “condensation” of psychic and spiritual realities. When the spontaneity and mystery of nature is penetrated, it becomes transparent. On the one hand it is transfigured under the lightning-flashes of divine energies, and on the other it incorporates and symbolizes those “angelic” states that fallen man can only glimpse for brief moments, when listening to music or when contemplating a human face. Symbols are not meant to be “stuck onto” things: they are the very structure, the presence, and the beauty of things such as they are in the process of perfection in God. For alchemy, which is the science of symbol, there was no question, as has sometimes been said, of a “material” unity of nature, but of a spiritual unity – one could almost say a spiritual Assumption of nature. For nature, ultimately, is none other than the place of a metaphysical principle: through man it becomes the body of the Word and, as it were, the bride of God.” Alchemy Journal 1: Alchemy: the Cosmological Yoga (by Maurice Aniane)
