Je Tsongkhapa 
Tantric Ethics [EPUB ebook] 
An Explanation of the Precepts for Buddhist Vajrayana Practice

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.
