Tantra, or Vajrayana, Buddhism is a set of esoteric practices that involve mantra recitation and complex visualizations. Tantra constitutes the fabric of a Tibetan Buddhist’s daily practice, but no practice of tantra can be successful without adherence to the tantric precepts, the highest of three complementary sets of vows. Tsongkhapa is perhaps the greatest philosopher ever produced by Tibet’s Buddhist culture, and this book is a translation of his explanation of the tantric precepts.

"The scholar and tantric adept Tsongkhapa (1357-1419), one of the greatest philosophers produced by Tibet's Buddhist culture, composed works on every aspect of Buddhist philosophy and practice. This book contains a translation of his Fruit Clusters of Siddhis, an explanation of the tantric vows, and provides a clear explanation of the nature of each vow and the criteria for determining when a downfall has occurred."--BOOK JACKET.
