Aum Shnrikyo is a religious sect founded by the 'Venerated Master,' Shoko Asahara (born Chizuo Matsumoto on March 2, 1955).
In 1984, the forerunner of Aum Shinrikyo, 'Aum Divine Wizard Association,' was established in Shibuya, Tokyo. Mr. Asahara is said to have attained final salvation in the Himalayas in 1986. In 1987, the samgha-system was introduced. In this, followers undergo religious training while living as a group. It was at this time that the headquarters of the group was transferred to Setagaya Ward, Tokyo.
In 1989, the sect was recognized by the City of Tokyo as a religious corporation, and in 1990, Mr. Asahara and a number of other top ranking officials of the sect announced their candidacies as Supreme Truth Party representatives for the House of Representatives. (None of them won.)
The group reveres Shiva as their chief god, and is involved in ancient yoga, primitive Buddhism and Mahayanist Buddhist teachings. The group's ultimate aim is to 'save all living things from transmigration.' The group is often referred to as a new Buddhist sect, but it also claims to be an original religion based on Hinduism and created by Mr. Asahara.
Mr. Asahara has prophesied that because of increasing evil the world is heading for a catastrophe at the end of the century. He says that in 1999 a nuclear war will erupt that will cause the end of the world. In order to prevent this, 30-thousand people must attain salvation, since only by spiritual awakening will holy energy be created to avert the coming crisis.
Based on the four main areas of doctrine, meditation, religious austerity, and initiation, there are three training systems called the yoga tantric course, siddhi course, and the bodha course. Through salvation and enlightenment ultimate happiness can be obtained. Followers aiming for salvation renounce the world and donate their personal wealth to the sect.

Jan. 2000: Name- and other changes
Faced with mounting government and police scrutiny, Aum Shinrikyo has recently distanced itself from its former leader, Chizuo Matsumoto (aka Shoko Asahara), admitting he may be directly responsible for the gas attacks and other crimes committed by the cult's members, changed its name to Aleph, and
announced other changes, including the demand that followers reapply for membership and sign declarations that they will obey the law.
Many observers view these moves with skepticism, noting that these changes come just before the government will decide wether Aum Shinriky should come under supervision in accordance with a law to regulate organizations that have committed mass murder.
