One of the enduring mysteries of the Aum Shinrikyo atrocities of the 1990s is the ease with which the cult attracted members. The arrest this month of the last two fugitives allegedly involved in Aum's fatal 1995 sarin gas assault on the Tokyo subway system recalls the whole ghastly episode, together with its unsolved riddles. What would draw sane, relatively prosperous, in many cases highly intelligent people to the incoherent blend of pseudo-philosophy, pseudo-enlightenment and pseudo-mysticism that elevated robbery, murder and terrorism into acts of religious devotion?

Even now, with cult founder Shoko Asahara and 12 leading disciples on death row, the cult, reconstituted as Aleph, continues to attract adherents. Why?

Probably no definitive answer is possible, and this certainly is not an attempt at one. But the business magazine Shukan Toyo Keizai provides a clue, though without making the connection. Its June 16 edition devotes 50 pages to an issue it fears is getting out of hand: depression.
