An essential tantric text on the practice of advanced yoga in tantric Buddhism.

This volume presents the Lamp in a thoroughly annotated English translation. It includes an introductory study discussing the history of the Guhyasamaja and its exegetical traditions, surveying the scriptural and commentarial sources of the Nagarjuna tradition, and analyzing in detail the contents of the Lamp. The book also features a detailed, trilingual glossary.

Simultaneously presented online for scholars are a version of its Sanskrit original, critically edited from recently identified manuscripts, and a critical edition of the eleventh-century Tibetan translation by Rinchen Zangpo, including notes on readings found in "lost," alternative translations.
