Oh yeah, there are heaps of people who are tuned into the power of sound vibrations...I've been onto that for at least 15 years now, and knew some women who teach about it. I've also met 2 different people who use the didgereedoo with intent to heal...and I remember an interview I read with John Frusciante from the red hot chilli peppers who said that all the band members felt that they were somehow healing people with their music...sound is very powerful and very healing. It's kinda my special thing
Let me know how you find the book if you get it? It also comes with a CD of his toning exercises, which I find very good for cleaning and aligning the chakras.
Oh, and if I'm ever in Spain, we might cross paths and swap roles...as ssandra said , there are plenty of peggers out there...we are just as curious about what it would feel like to have a penis as you are with vaginas.
