This is a free introductory course into Lei Fa, a classical form of Taoist sorcery. Lei Fa (雷法), translated into English as Thunder Rites or Thunder Magic, is a tradition of ceremonial magic and Chinese occult craft that rose in popularity during the Song Dynasty of China (A.D. 960—1279). In Eastern esoteric traditions, Lei Fa is considered one of the more advanced practices.
There are both inner and outer alchemical forms of Thunder Rites. Methodologies are premised on the belief that thunder is the divine command of Heaven and a practitioner can harvest the power of thunder to absorb powers from Heaven and use those powers to both exorcise demons and heal sickness (because, for the most part, historically sickness was attributed to demonic possession).
