The foundational teachings of Buddhism—presented here in volume one of Chögyam Trungpa's magnum opus, which offers a systematic overview of the entire path of Tibetan Buddhism

This three-volume collection presents in lively, relevant language the comprehensive teachings of the Tibetan Buddhist path of the hinayana, mahayana, and vajrayana. Considered Chögyam Trungpa’s masterpiece, The Profound Treasury of the Ocean of Dharma will resonate with new and senior students of Buddhism.
 
Chögyam Trungpa begins his study by presenting the teachings of the hinayana. The hinayana introduces core Buddhist teachings on the nature of mind, the practice of meditation, the reality of suffering, and the possibility of liberation. It examines the nature of suffering, impermanence, and egolessness, with an emphasis on personal development through meditative discipline and study. The formal entry into the hinayana and the Buddhist path altogether is the refuge vow, in which a student goes for refuge to the Buddha, or the teacher; the dharma, or the teachings; and the sangha, or the community. The hinayana path is based on training in mindfulness and awareness, cultivating virtue, and cutting grasping.
 
Topics covered in detail in this volume include the four noble truths, karma, the four foundations of mindfulness, meditation practice, the refuge vows, the three jewels, the five skandhas, the five precepts, twofold egolessness, and more.
