The text presented here in Tibetan with English translation is the Bountiful Cow of Accomplishments and provides directives for the two phases of the Khandro Thugthig. It covers the entirety of the Vajrayana path, from the generation phase, through the completion phase to the Great Completeness. The Khandro Thugthig is an important cycle of teachings and practices revealed by Dudjom Rinpoche (1904-1987) as a spiritual treasure. Among the three roots of tantric practice, it specially relates to the sky-farer. The directives translated here are most closely associated with Yeshe Tsogyal, the Tibetan princess who became the consort of the great master Padmasambhava and assisted him when in the eighth century he introduced tantric Buddhism to Tibet. But Yeshe Tsogyal is more than a historical figure, for she is a wisdom sky-farer who inspires yogins to realize the ultimate nature of mind. The instructions translated here are both rare and profound. Those sincerely interested in these teachings and who wish to put them into practice may rejoice that such profound keys have been made available to them. For those having a karmic connection with this tradition and this lineage, texts such as these can be a catalyst for spiritual liberation. This text is intended for those who have received the transmission from a qualified master.
