The heart of meditation—the thing that brings it alive—is compassion. Without that essential foundation, other practices are pointless. Fortunately, the mind can be trained in compassion, and the mind thus trained with the qualities of love, empathy, kindness, and respect for others is ready for the practice of the Great Completeness (Dzogchen), which is considered the pinnacle of spiritual practice in the Nyingma tradition of Tibetan Buddhism. His Holiness the Dalai Lama here teaches the Great Completeness simply but thoroughly, using as his reference a visionary poem by the nineteenth-century master Patrul Rinpoche to show that insight can never be separated from compassion. Through practice of the Great Completeness, we can access our innermost awareness and live our lives in a way that acknowledges it and manifests it. The wisdom and compassion that arise from such insight are critical, His Holiness teaches, not only to individual progress in meditation but to our collective progress toward peace in the world.
