Tenzin Wangyal rinpoche, a master of the bon religion, ancient tibetan religion pre buddhism there, is reciting the guided vocal meditation. It is chanting but I cannot do it anymore because I have smoked too much and no longer have the breath required to chant. I bought that cd 2 or 3 times over the last 20 years.
It is a beautiful cd , I highly recommend it. Very positive and for once, perfect english from a tibetan native speaker.
