This work represents a very complete study of the transpersonal dimension of Jewish spirituality. Contrasting modern psychological theories with the oldest traditions of Jewish mysticism (especially the powerful symbol of the Tree of Life and its different dimensions), Mario J. Saban reveals a fascinating image of the "I" as understood by the ancient wisdom of the cabal. Naturally, it is an "I" that embraces and transcends the psyche. What emerges is a detailed picture - exhibited with commendable scientific rigor and clarity - of how the human psyche can grow through higher states of consciousness. An essential work on Jewish mysticism and the spiritual knowledge of the human being.
