OTO or O.T.O.
Abbreviation for Ordo Templi Orientis
Ordo Templi Orientis (O.T.O.) ('Order of the Temple of the East' or 'Order of Oriental Templars') is an international fraternal and religious organization founded at the beginning of the 20th century by Carl Kellner and Theodor Reuss. English author and occultist Aleister Crowley is the best-known and most influential member of the order.
Originally it was intended to be modelled after and associated with European Freemasonry, such as Masonic Templar organizations, but under the leadership of Aleister Crowley, O.T.O. was reorganized around the Law of Thelema as its central religious principle. This Law—expressed as "Do what thou wilt shall be the whole of the Law" and "Love is the law, love under will"—was promulgated in 1904 with the writing of The Book of the Law.
Similar to many secret societies, O.T.O. membership is based on an initiatory system with a series of degree ceremonies that use ritual drama to establish fraternal bonds and impart spiritual and philosophical teachings.
The O.T.O. also includes the Ecclesia Gnostica Catholica (EGC) or Gnostic Catholic Church which is the ecclesiastical arm of the Order. Its central rite, which is public, is called Liber XV, or the Gnostic Mass. 
Black Sun Program
Aleister Crowley was contacted in 1904 by the NAA and is the Black Sun poster child of the last century, he was given power and Essene Gnostic knowledge to spread the OTO into the related satanic practices, in order to build the Black Magic Grids or Thothian grids worldwide for supporting the control network for the Power Elite. These are essentially the infiltrations that were made into the Planetary Grid Networks that are used today to support the Power elite rituals through the use of black magic sorcery, making their Mind Control sorcery and blood rituals more effective. The Power elite draw upon a massive energetic field harvested from human Souls that was generated specifically for them, in order to maintain the highest levels of wealth in the pyramid of global control.
