Aum Shinrikyo recruited from Japan's best universities. Its senior figures included graduates in physics, chemistry, medicine and engineering from Tokyo, Kyoto and Osaka — people with the technical capacity to synthesize nerve agents, which is what the group eventually did.
That recruitment profile is the first thing to understand about the case, because it contradicts the folk model in which cults collect the weak-minded. Aum offered structure, discipline, meaning and a comprehensive explanation of the world to young people who were academically successful and spiritually unanchored, and the offer was well matched to them.
Shoko Asahara, partially blind from birth, had failed to get into medical school and had been convicted of selling fake medicine before founding a yoga school that became a religion. The organization received official recognition as a religious corporation in 1989.
Its control methods were unusually physical.
Initiations involved prolonged isolation in small cells, extreme heat, restricted food and sleep, and the administration of hallucinogens including LSD. Members drank Asahara's blood and bathwater in rituals with substantial fees attached. Some wore electrode headsets said to synchronize their brainwaves with the guru's. Practitioners who wished to leave were sometimes confined.
The doctrinal instrument that made mass murder executable was a single word.
Poa, borrowed from Tibetan Buddhism and radically reinterpreted, held that a person accumulating bad karma could be spiritually benefited by being killed before they accumulated more — that killing them was an act of compassion that improved their next incarnation, performed at spiritual cost to the killer.
This is euphemistic labelling of the kind chapter 76 describes, and it is the most complete example in this guide. It does not ask the follower to overcome moral revulsion. It redescribes the act so that revulsion does not attach, and it inverts the moral valence entirely: the killer is making a sacrifice.
The group killed a lawyer, Tsutsumi Sakamoto, along with his wife and infant son, in 1989. It released sarin in Matsumoto in June 1994, killing eight. On 20 March 1995 five members punctured bags of sarin on three Tokyo subway lines during the morning rush hour. Thirteen people died and thousands were injured, some permanently.
Asahara and twelve others were executed in July 2018.
Successor organizations still exist and are monitored. Japan's Public Security Intelligence Agency continues to report on them, and the doctrinal material remains in circulation.
