This book presents the practice and theory of Tibetan Buddhism. First is a meditation manual written by the Fourth Pan-chen Lama (1781-1852), based on Tsongkhapa's Three Principal Aspects of the Path, which covers the daily practice of Tibetan monks and yogis. It details how to properly conduct a meditation session that contains the entire scope of the Buddhist path. Next is the Presentation of Tenets, written by Gon-chok-jik-may-wang-bo. It covers Indian Buddhist schools, as viewed in Tibet, and provides a solid introduction to the Buddhist theory animating the practice. Topics include the two truths, consciousness, hindrances to enlightenment, paths to freedom, and fruits of practice.
