The Essential Jewel of Holy Practice is a vibrant philosophical and ethical poem by one of Tibet’s great spiritual masters. Patrul Rinpoche presents a complete view of the path of liberation from the perspectives of the Madhyamaka understanding of emptiness and the Mahāyāna ideal of compassionate care refracted through the Dzogchen perspective on experience. This yields a sophisticated philosophical approach to practice focusing on the cultivation of clear, open, luminous, empty awareness and of liberation leading to the transformation of one’s moral capacity and sensitivity. Patrul Rinpoche’s verses speak intimately and directly to the reader and inspire one to develop one’s mind for the sake of ethical perfection and liberation. The translators’ introduction provides a foundation for reading the poem and their commentary to the verses assists the reader in understanding Patrul Rinpoche’s allusions and technical terms.
