here is the info of a book and cd that i have recently found to be helpful. i always check my local library first as often the title is there, and saves me buying it without checking it out first.
donna farhi,'the breathing book'. lots if simple exercises and suggestions, and works very well with learning the key sound.
and another thing i am trying, and i got this idea from pan, is the cd 'ecstasy', from brain sync.com . alpha and theta waves to help one to relax and open to deeper sensuality. i quite like the effect and the music is simple and undemanding.
cheers to all!
