An extremely interesting but highly esoteric aspect of plant salts is that they also act in a manner reflecting their geometric shapesshapes that have direct relationships to the planetary correspondences of the plants. Therefore, if we examine the calcined salt of a plant under a microscope, we will see that it has a specific shape and form. For example, salts of a cubic crystalline form relate to Saturn and can be used to assist in all areas in which the energies of Saturn are needed. This can be used to help us in deciding the correspondences for plants that are not listed in the traditional alchemical herbals.
This theory also demonstrates the Qabalistic theory of "Four Trees in Four Worlds," wherein the earth, or mineral, Tree is the first to form but the last to be animated with consciousness. Through the addition of mineral substances to our work, we not only anchor our work solidly in the material world, but also assist the mineral world in its evolution. The more we work with the salts of our plant products, the closer we bring the entire process into the realm of genuine alchemy, and by that we mean a transformative practice for both matter and energy.
