If you want enlightenment via Alchemy, I invite you to revise your spiritual motivations profoundly concerning the possible fulfilling of this goal with this Art. One person upon a billion, even less, can reach enlightenment via Alchemy. It's far more direct by other paths, those who walk these paths of Material realization have a very special quality of soul, requiring a lot of Hermes in it. This is why oratory is required (which must be made of astrologia, theurgia, and study of symbols, texts, meditation (zen like) and also the different laws of Nature), and of course and practical side made with the laboratory, both are one and complete each other.
Most part of process revealed today are part of the said "particular Alchemy". Nothing Universal is involved, but these paths can lead to interesting medicines, transmutations, learning about the process, qualities of matter, laws of Nature, and mastery of inner archetypes, also balancing inner energies etc, and attaining minors states of initiation or purification. These paths are for example the Antimony path of Bacstrom, of "Flamel" as they call it in the PON, involving silver, gold, mercury and antimony (Flamel Path is not at all the path described here), or the Roger's Caro Cinnabar Path, all the different Alkhaests Paths also, the Golden Water Path or Via Antiqua, etc.
Alchemy has a lot of ramifications, like the roots of our old oak. And it is a complex subject.
I want to thanks all my friends in the Art for their support, help, contributions. Thank you my friends !!
