Leo Schaya (1916-1985) was born in Switzerland, where he received a traditional Jewish upbringing. From early youth he devoted himself to the study of the great metaphysical doctrines of East and West, particularly the works of neo-Platonism, Sufism, and Advaita Vedanta. Along with some other writers in the so-called Traditionalist/Perennialist school, Schaya is noted for his grasp of sometimes difficult metaphysical concepts and his ability to summarize and interpret the writings of ancient and medieval sages for current readers. In 1958 he published his much heralded book The Universal Meaning of the Kabbalah on the metaphysical and esoteric wisdom of the Jewish Kabbalah, which remains one of the most often quoted books on the subject. He also wrote a book on the transcendent unity of all three Abrahamic faiths. More recently (2014), a collection of articles on Jewish esoteric tradition entitled Universal Aspects of the Kabbalah and Judaism was published.
""Schaya's writing is often dense, but it is the density of passion: his words are charged with a spirit of love and wonder which it is difficult not to share. For him, despite all its rigors and perils, 'the Kabbalah is like a fountain of youth in which one is spiritually reborn again and again on one's inner path towards the infinite.'"" --Temenos Academy Review ""Schaya's writings on the Kabbalah plumb the rich well of the Torah, and particularly its mystical dimension, in order to illuminate the fullness of the Jewish tradition. He has provided an unerring compass which may guide us through many of the pressing dilemmas confronting the modern world. His work allows readers within the fold of the Judeo-Christian tradition, as well as those from other faiths, to perceive the reality of our common heritage in the One, and then to think and act accordingly."" --Samuel Benedeck-Sotillos, The Journal of Transpersonal Psychology ""This book fills an urgent need, for to rediscover the deepest meaning of the Old Testament is something that could have a most tonic and enlightening effect on the whole of Christian thought today; and for this, no clearer interpreters are to be found than the masters of the Kabbalah."" --Marco Pallis, author of The Way and the Mountain
