Nineteenth-century Tibetan mystic Tertön Sogyal was a visionary, whose mastery of meditation led him to be a revered teacher to the Thirteenth Dalai Lama. Known for his deep spiritual insights and service to the nation of Tibet, Tertön Sogyal's ability to harness the power of the mind was born of both his profound understanding of the Buddha's teachings and his unique experiences, all the while striving for peace against tremendous odds. His life is an example of courage and diligence appreciated by spiritual practitioners of all traditions; and his practical instructions on meditation and opening one's heart--amid conflict, uncertainty, and change--are as relevant today as they were during his lifetime.   Fearless in Tibet, the first comprehensive work in English on Tertön Sogyal, captures the essence of his teachings and his inner world of visions and spiritual realizations.
