Often referred to as the "soul" of the Torah, the Kabbalah is an ancient Jewish tradition which teaches the deepest insights into the essence of G-d, His interaction with the world, and the purpose of Creation. Kabbalah teaches the essential Jewish cosmology, integral to all other Torah disciplines. Sometimes called "the Inner Torah" or the "Wisdom of Truth", it offers a comprehensive overall structure and plan for the universe, as well as a detailed understanding of the particulars of our lives. The student of Kabbalah is made aware of the personal as well as the collective rectification process and is encouraged to play an active part in it. Judaism is based on the public Revelation at Sinai, when the Torah was given to Israel. The historical event of Sinai attests to the divine source and nature of the Torah, and the Torah in turn serves as the exclusive criterion for any subsequent claims and teachings. The general term for Jewish mysticism is "Kabbalah". "Kabbalah" means "tradition". Kabbalah is not a compound of personal insights. It is not a collection of reports of what various sages and saints had to say on the meaning of life and ultimate values - based on their mystical experiences or visions. It is not a system born in a vacuum.Authentic Jewish mysticism is an integral part of Torah, and Torah determines what is authentic Jewish mysticism. Kabbalah and its teachings - no less than Jewish Law - are an integral part of the Torah. They are traced back to the historical roots of Sinai, part and parcel of "Moses received the Torah from Sinai and transmitted it…." To be sure, in various works of Kabbalah one can find reports of mystical experiences, visions, the supernatural - all those things and more which we normally link to mysticism. They are there, but they are not the essence or even a major part of Kabbalah. At best they are effects, possibilities of potential effects that may accompany a mystic's life. The authentic mystic, however, will not seek to manipulate and will shun interference with the natural order instituted by the Creator. The authentic mystic seeks knowledge, understanding. He wants to "Know theG-d of your father", to fulfill the precept of "You shall know this day and consider in your heart that G-d He is G-d in Heaven above and upon the earth below - there is nothing else." He seeks to realize and understand this axiom not only as an intellectual affirmation of truth but as a living reality within the limits of his capacity - profoundly sensing the literal omnipresence of G-d, with a penetrating understanding and knowledge, as much as possible. Kabbalah is theology in the fullest sense - including ontology, cosmogony and cosmology. It is not speculative philosophy based on human insight nor theories derived from human reasoning. It is a study, as it were, of Divinity and of the relationship between G-d and His Creation, based on the premises of revealed truth. It is the very core and soul of Torah, the ultimate revelation of Divinity - exposing the inner meaning, effects and purpose of Torah and mitzvahs. The illumination emanating from Kabbalah ignites the soul of man, setting it on fire in the awareness of a deeper and higher reality. Its study and insights are themselves mystical experiences. Kabbalah is all this - but always and exclusively within the context of Torah. As a body cannot function without a soul, so the soul is ineffective without the body. The soul of the Torah, (_nistar_, the esoteric part of the Torah) can never be separated from the body of the Torah (_nigleh_, the exoteric parts; _halacha_, the commandments and practices prescribed by the Torah). Kabbalah reduced to spiritual or philosophical symbolism, stripped from the observance of the _mitzvahs_, is worthless mumbo-jumbo, an empty shell.
