US Bishops release statement ruling-out Reiki

Catholic Culture gives us the brief:

In a document released March 25, the Committee on Doctrine of the United States Conference of Catholic Bishops blasted Reiki, a practice developed in Japan in the late nineteenth century that has gained acceptance in some Catholic retreat centers and other institutions.

... The bishops add, “Some forms of Reiki teach of a need to appeal for the assistance of angelic beings or ‘Reiki spirit guides.’ This introduces the further danger of exposure to malevolent forces or powers.” [more from Catholic Culture or the MSM.]

Well, I guess it's a good sign when I first hear about something bad ... when the bishops publish a document telling me it's bad. But has anyone come across this stuff? I mean, what made it such a priority for the bishops?

update: from comments, it's evident to me that this was becoming a widespread abuse. thanks for the context, papists! please continue to keep me posted in the comment thread. this is a dangerous practice.
