**“There’s no sounder or more sage guide to alchemy – the practice and the philosophy – than Brian Cotnoir. This wise, lucidly-written book … offers explanations and exercises that will be of immeasurable help to anyone hoping to navigate this enormous field.” – Sukhdev Sandhu** Alchemy is both the art of transmuting base metal into gold and a powerful metaphor for spiritual transformation and creativity. This simple guide contains all you need to know to become an alchemist – to decode the most complex alchemical texts, to unite your inner spiritual work with your outer work, and to take up laboratory alchemy if you so wish. Whether you are a beginner intrigued about the possibility of spiritually enriching your life and creativity, or a practising alchemist looking for the key to difficult texts, *On Alchemy* invites you to embark on a profound journey of personal change. It is full of meditations, visualizations and other practices to guide you on your way, from using geometry to purify your inner eye, to questioning the gods in your dreams, to using a circulation and distillation apparatus.
