In this compelling psychological memoir, Keiron Le Grice, the 2023 Zurich Lecture Series' speaker, details his experience of a profound transformative crisis between 2001 and 2004. He explains how, by a sustained investigation of the root causes of his condition, he was eventually able to overcome the crisis, guided by instructive dreams and startling coincidences, illuminated by a series of symbolic paintings, and aided by his serendipitous discovery of the Gnostic text The Gospel of Thomas. Exploring the nature of the unconscious mind and the mysterious spiritual power behind his experience, Le Grice turns to the mystical symbolism of alchemy and the psychology of Carl Gustav Jung to set out a deep understanding of psychological rebirth and its relationship to the ongoing evolution of the Western psyche. The Lion Will Become Man gives a striking example of alchemy at work and reveals its great value as a guide to the complex developmental process that Jung called individuation.
