A good source for Buddhist teachings is the KPFK archives (http://archive.kpfk.org/parchive/). Search for "Something's Hapenning". Thursday Night is the night they usually play meditation and spiritual stuff. Be warned: some of it is really good, but a lot of it is extremely hokey.

It seems like more poorly researched science reporting from the Times.
