DILGO KHYENTSE RINPOCHE (1910-1991) was a highly accomplished meditation master, scholar, and poet, and a principal holder of the Nyingma lineage. His extraordinary depth of realization enabled him to be, for all who met him, a fountain of loving-kindness, wisdom, and compassion. A dedicated exponent of the nonsectarian Rime movement, Khyentse Rinpoche was respected by all schools of Tibetan Buddhism and taught many eminent teachers, including His Holiness the Dalai Lama. He tirelessly worked to preserve and propagate the Buddhist teachings through giving transmissions and instructions to thousands of people across the world, publishing important texts, and building monasteries and stupas.

The path of trekchö is the way of directly and thoroughly cutting through the misconceptions of samsara to lay bare the primordial purity of the nature of mind. This powerful practice is illuminated by Dilgo Khyentse Rinpoche in his commentary on an essential text based on the atiyoga dzogchen instructions of the outstanding nineteenth-century master Patrul Rinpoche.
Three Words That Strike the Vital Point is the famous seminal statement by Garap Dorje that is said to encapsulate all the myriad dzogchen tantras. The key instructions on it by Patrul Rinpoche—the verses known as "The Special Teaching of Khepa Shri Gyalpo"—form the basis for the discourse in Primordial Purity. It explains that in dzogchen, when one has fully recognized that all the confusion of samsara is the expressive power of great emptiness, confusion is spontaneously liberated into the primordial purity of mind's essential nature. Compassion spontaneously arises, accomplishing the benefit of sentient beings. Dilgo Khyentse Rinpoche illuminates this beautifully in this profound work, which will inspire students of Buddhism and deepen their experiential appreciation of the teachings.
