This title was originally meant to discuss the essence and activity of the demonic forces in Lurianic Kabbalah, but was expanded as a monograph dealing with the main principles of the Lurianic Kabbalah as a whole. The research is based mainly on the writings of Hayyim ben Joseph Vital, a student of Rabbi Luria. The author comes to the conclusion that from the Lurianic Kabbalah arises a bold myth of a covert ancient dualism of divinity, in which dealing with evil forces serves as a central element. This short study is the first in a comprehensive investigation of Lurianic Kabbalism.
