With the help of an excellent shamanic teacher, I discovered (or more accurately, reconnected with past-life experience) the joy of trance journeying aided by steady drumming. But then it was time to go back home where I had no one to drum for me. Then one day, up pops an Amazon recommendation for Drumming to Journey By---and it's designed by the author of The Reluctant Shaman, a book of which I am very fond. This CD quickly became an invaluable tool for my self-discovery. In the liner notes, Kay mentions that crystal singing bowls were activated by the drumming as the CD was recorded. My conscious self tried to hear the bowls and couldn't, but on my very first journey, I entered a cavern lined in crystals which began to vibrate with the drum-beats; THEN I could hear the crystals singing. So much subtle texture to the rhythm!
