Patrul Rinpoche, the beloved nineteenth-century master best known for Words of My Perfect Teacher, collected the teachings of the tenth-century adept Aro Yeshe Jungne and synthesized them into the short text translated here as Clear Elucidation of True Nature. How to put these essential teachings into practice is the subject of the lively commentary by the two Khenpo brothers, the late Khenchen Palden Sherab Rinpoche and Khenpo Tsewang Dongyal Rinpoche.

The Dzogchen meditation instructions of the Aro lineage are divided into nine sets, or nine levels, with specific instructions for each on how to identify the nature of the mind, how to abide in it as a way of life, and how to liberate turbulent thoughts and emotions when they arise. The commentary enfolds this instruction into a broad general teaching suitable for beginners that serves as an introduction to Dzogchen meditation, to the Nyingma tradition, and to basic Buddhism.
