All True Religions see the same Light, but from different perspectives. Many attempts to reconcile the mystical philosophies of Greek, Judaism / Hebrew, Egyptian Zoroastrian and Christian thought have traced out a subset of mysticism that avoids the dualism of Zoroaster and it's condemnation of the Material World to exalt it as both the finest WORK of the Creator and made up of the Creator's essence. It finds in the Zohar the theory of the Tsimtsum, God withdrawing Himself into Himself to make a Space without the Godhead, then exhaling a word (YHVH) to Create the material world out of HIS own Being.
The underlying esoteric theme of the initial Unity of everything as part of God's substance, brought to potential and material existence, and returned to it's source is in direct contrast to the Abrahamic religions of Judaism, Christianity and Islam exoteric message of Creation. Aristotle postulates a world that has always existed, and in the Middle Ages of Europe, in the Golden Age of Islam, and in the chaos of proto - Spain Andalusia and Cordoba, the wisdom of the Ancients was being saved. In Persia and Cairo, and later Spain, Christians read Greek & Latin to Jews who read Hebrew & Aramaic / Syriac with Muslims who wrote Syriac & Arabic, to create a House of Wisdom. A similar process after the fall of Constantinople drove Greek speaking Christians to Italy, where Marsilio Ficino, Giovanni Pico della Mirandola and John Argyropoulos resurrected the Florence Platonic Academy and kick-started the Renaissance.
Perhaps the first of the Gnostic Rabbi's was Rabbi Philo of Alexandria, who was well versed in the Greek philosophy represented in that great Library while maintaining his Religious monotheism. This assisted his successful negotiations from a position of no power with crazy Emperor Caligula in Rome. He grew up under Roman rule, with Greek intellectualism and and ancient monotheistic faith from 20 B.C.E. –50 CE, and may have influenced the Essene sect of St. John the Baptist and Jesus the Christ. The ideals of Plato and logic of Aristotle were powerfully attractive, as interpreted by the Neoplatonists like Plutarch and later influencing Hermes Trismegistus (date unknown, but @ 100 CE?) , Valentinus (AKA Valentinius), 100 - 160 CE, Iamblichus, 245 – 325 CE; Plotinus, 240 - 270 CE; Porphyry, 234 - 305 CE; & Proclus, 412 – 485 CE;
He took on the task of blending the inner wisdom of the Oral Torah, the Qabalah aka Kabbalah aka QBLH... with this Greek current of Philosophy. In this he was guided by the teachings of Rabbi Shimon bar Yochai AKA Rashbi, believed to be author of the Zohar & Rabbi Akiva's messianic visions, part of the Essene and early Christian fervor. Later Qabalists like Isaac Luria aka Ari, the Lion; Moses de Leon and Moses ben Jacob Cordovero translators of the Zohar, Abraham Abulafia @1275, and other Qabalists added greatly to the Hebrew version of this Gnostic theory of God hidden within Creation.
Avicenna aka Ibn Sina, Iran 980 – 1037 CE, an Islamic scholar, attempted to reconcile Aristotelianism and Neoplatonism with Islam. The political situation was unsettles, he was... difficult, but on the plus side, while incarcerated he developed the "Floating Man" thought experiment. A medical doctor and scientist, he nevertheless believed in Intuition over the Senses. Aristotelianism becomes Avicennism which becomes Averroism in Western Europe. Alhazen was perhaps his greatest scientific student, but not his greatest Philosophical student.
Solomon ibn Gabirol aka Avicebron in corrupted Latin, Moorish Iberia / proto-Spain, 1021 - 1058, was a poet in Hebrew and Neoplatonist philosopher in Arabic. Emanations from the Godhead ARE the material World, it doesn't just create it as a separate "thing". He was mistaken for a great Christian or Muslim philosopher until his original Hebrew poems resurfaced and was noted as the source of the Latin, which had been taken from Arabic translations @ 1850;
and Averroes aka Ibn Rushd aka The Commentator (on Aristotle, primarily), Moorish Iberia / proto-Spain, 1126 – 1198; although said to have influenced Moses Maimonides, his concerns were of the inner Soul, not outer behavior; Mathematician, scientist, mystic and translator of the Ancients for St. Thomas Aquinas and the Thomists, Peter Abelard in France and Duns Scotus, in addition to the official “Averroists”, Christian and Jewish students of Europe, Egypt and Iran; His solution was that God was outside of Time, and thus Human's could not understand God and the Creation in our limited Human terms. So, like Heisenberg's Uncertainty Principle, God always existed, could create the World at any time, did so, but while Time continued forever for God, it is limited for Humans, who perceive its stops and starts in the world, its beginnings and endings.
