Aloha Skipper,
We used "crystal bowls" set for each of the chakras at the Learning Strategies retreat a year back, in conjunction with a auditorium-sized labyrinth one night. Very nice.
Paul MC's last week's 6-day Spring Forest retreat here in Minneapolis, and started the day with an invocation.setting intention with the use of one of two toned crystal bowls.
The Ohms & Mauh's in the Small Universe and the sounds you make when doing the six-word chant (as found in his "Born A Healer" book and "Your Healing Power" DVD), are resonating with different organs and systems for healing as well.
Much Love, Shawn
