The Treasury of Precious Instructions by Jamgön Kongtrul Lodrö Taye, one of Tibet's greatest Buddhist masters, is a shining jewel of Tibetan literature, presenting essential teachings from the entire spectrum of practice lineages that existed in Tibet. In its eighteen volumes, Kongtrul brings together some of the most important texts on key topics of Buddhist thought and practice as well as authoring significant new sections of his own.

In this, the eighteenth volume, Kongtrul expands on The One Hundred and Eight Guidebooks, a collection of teaching manuals compiled by the sixteenth-century Tibetan master Kunga Drolchok, adding Indic source texts, Tibetan antecedents, and later interpretations. Though compiled by a Jonangpa abbot and transmitted by the Jonang tradition, these teaching manuals are actually drawn from the Kadam, Sakya, Kagyu, and, to a lesser extent, Nyingma traditions. They are succinct and impart practical wisdom, as transmitted by key figures like Kunga Chogdrub and Lowo Khenchen Sonam Lhundrub. Gyurme Dorje, the translator, provides extensive notes and helpful context throughout. The resulting volume preserves and integrates the diverse lineages of Tibetan Buddhism while providing useful advice to practitioners.
