The Black Art (2013), the fourth e-book, will soon be available for download. It contains all of my work on the subject of alchemy, including the following: a lucid presentation on the formative principles (the four elements, the seven planets and metals, and the tria primaunio mystica with the transpersonal or true Self); the cosmographical implications of the last four plates of the Splendor Solis; and an in-depth expose of the alchemical stages as a psychological process.
