Constitutes the fabric of a Tibetan Buddhist's daily practice, but no practice of tantra can be successful without adherence to the trantric precepts, or vows. Tsongkhapa, the founder of the Dalai Lama's tradition is perhaps the greatest philosopher ever produced by Tibet's Buddhist culture.
Tsongkhapa Losang Dragpa (1357-1419) is arguably the finest scholar-practitioner produced by the Buddhism of Tibet. Renowned for both his written works and his meditative accomplishments, he founded the Gelug school, which produced the lineage of the Dalai Lamas. Gareth Sparham was a monk for more than twenty years and an oral interpreter for many learned lamas while living in India. He holds a PhD in Asian Studies from the University of British Columbia. The author and translator of numerous works, many focusing on the writings of Tsongkhapa, he has taught Tibetan language at the University of Michigan at Ann Arbor and the University of California at Berkeley. He lives with his wife in Walnut Creek, California.
