I found out today that Tricycle magazine has kindly put an important and thought provoking interview in that context online. Lawrence Shainberg interviewed academic expert Robert Jay Lifton in From Mysticism to Murder on Aum Shinri Kyo.

What does this really say, that they met?
The interview puts the meetings of Shoko Asahara with the Dalai Lama into context. However, the whole interview is worth to be read and to be reflected upon – not just only the passage that deals with the meetings of Shoko Asahara and the Dalai Lama – because it shows the dangers of gradually growing fundamentalism / dogmatism / totalitarism in a group; especially when there is a guru who abuses the guru-teacher relationship in order to gain total control over his devotees.
A must read in that context is Robert Jay Lifton’s Destroying the World to Save It: Aum Shinrikyo, Apocalyptic Violence, and the New Global Terrorism.
