In 2008, in Manhattan, I witnessed one of the most amazing spiritual rituals ever: the Tum Ngam Terrifying Deity (CHAM) Dance performed by the monks of Trongsa Fortress (Bhutan). Recently, as other Dharma Wheel Forum posters have noticed, I have been going through a spiritual journey to experience the vastness of human reality (ie I am looking for more than my post-industrial retail job life) and asking for resources on various schools. A few months back, I just learned that the monks are part of a Kagyu lineage called the Drukpa. I wish to study more about these remarkable folks.
Thus, what's a good book or website on the theological beliefs and rituals of the Drukpa lineage? I am specifically not looking for philosophical discourses.
