There are a number of branches of the Drukpa Kagyu and each has its own liturgies for doing the preliminary practices (ngondro). The Kham (East Tibetan) tradition of the Drukpa Kagyu, headed by the Khamtrul Rinpoches has a number of these liturgies. However, the one composed by Kunga Tenzin, the Third Khamtrul Rinpoche is the one most often used. It is the liturgy used for example at Tashi Jong in India, the present day seat of Khamtrul Rinpoche.
The text of the liturgy was translated into English by Tony Duff at the request of Tsokyni Rinpoche. It is a standard, Mahamudra style preliminaries liturgy in which there are four sets of one hundred thousand preliminaries to be done. Kunga Tenzin included a lot of material in his liturgy and this makes it useful as a reference for anyone. For example, the whole laying aside practice done with the practice of the Thirty-five Buddhas and the Sutra of the Three Heaps is contained in it. There is also a magnificent guru yoga section for the Drukpa Kagyu, which is exceptionally beautiful, plus a collection of dedication prayers at the end.
The liturgy should be of special interest to all Drukpa Kagyu followers. More than that, it should be of interest to anyone doing the preliminary practices.
