Charles Mopsik (1956-2003), a leading Kabbalah specialist, here presents, with a precise and accessible overview, the key figures among Kabbalists and introduces the reader to the essential texts addressing critical spiritual questions: how is the infinite of the upper worlds structured? How does the Divine manifest in order to act through us? How can we, in turn, help it to act? The Kabbalah, an esoteric Jewish tradition, has seen its influence reach all areas of thought. An initiatory journey, this book is also an invitation to an alternative take on the reading of two histories: that of humanity and one’s own personal history.
