Last October I gave a lecture called Channeling and Creativity at the Houston IONs meeting. Turnout was great and we had a really interesting discussion afterwards about the pros and cons, risks and benefits, and whether everyone can or should channel. There was no video but an audio version of the talk is available here.
Here is a PDF of the slides so that you can follow along pretty closely because I say "next slide" whenever I switch slides: Channeling and Creativity Slides PDF
Thanks to Houston IONs for hosting the event, and to Merrie Michaels for her kind introduction.
