Ngondro commentary: instructions for the concise preliminary practices of the new treasure of Dudjom

The ngondro, or preliminary, practices are the foundation of Vajrayana Buddhism. The Dudjom Tersar ngondro, a treasure revealed by Dudjom Lingpa, a previous incarnation of Dudjom Rinpoche, is a concise, yet very powerful set of practices for turning the mind to dharma, purifying obscurations, accumulating merit, and opening the door to the mind's true nature through guru yoga.
