From the Heart of Chenrezig The Dalai Lamas on Tantra

The lineage of the reincarnated line of Dalai Lamas has held primary spiritual authority and, until recently, temporal power in Tibet since the beginning of the fifteenth century. The translations in this book represent a curated set of their writings specifically on tantra, the advanced path of Tibetan Buddhism in which practitioners use a variety of methods and techniques to directly overcome delusion and conflicting emotions. If one has the proper training in sutra and tantra, it is said that the path to enlightenment can be traversed swiftly. Glenn H. Mullin, one of the foremost translators of the Dalai Lamas, has selected key texts from eight of the Dalai Lamas that clearly elucidate the proper understanding and context of the tantric system in this lineage.

Glenn H. Mullin is an internationally renowned Tibetologist, author, and expert on Buddhist meditation. He lived in Dharamsala, India, the home of the Dalai Lama, for many years, where he studied Tibetan language, literature, yoga, and meditation under twenty-five of the greatest masters of Tibet. He is the author of over fifteen books on Buddhist topics and has led many pilgrimages to Nepal and Tibet. He now divides his time between writing, lecturing, giving, workshops, and leading pilgrimages to the power places of Central Asia.
