Traduz. dal tibetano di Erik Pema Kunsang. A cura di Marcia Binder Dchmidt, Kerry Moran. Boudhanath, Rangjung Yeshe Publications 1997, cm.15x22, pp.199, brossura, copertina figurata a colori. Testo in inglese. This translation contains subtle and penetrating wisdom expressed through the age-old tradition of spiritual songs. Two songs by the great Indian master Naropa are explained in detail by Thrangu Rinpoche, a realized Tibetan Buddhist teacher of the present time. His approach is traditional, but his style is conversational and pragmatic. He includes refutations and limitations of other approaches, a comparison of Mahamudra vs. regular Shamatha, 5 wisdoms, as well as the 6 paramitas. Reading this book, one realizes that Mahamudra ultimately encourages turning the eye on the "I."
