Shangkarwa Rinchen Gyaltsen
Shangkarwa Rinchen Gyaltsen was born in the female water snake year to father Ponyig Zangpopal and mother Josema Palchen. When he was three both his parents passed away and he was placed under the tutelage of two monks, Shakya Senge and his uncle Rinchen Öser, who taught him how to read and write. Shangkarwa took novice vows at the age of eight. At the age of twelve he went to a large temple in Zamtsar and took further vows before the abbot Zepa Gyaltsen and Shakya Pal and received the name Shangkarwa Rinchen Gzaltsen. He took full ordination at the age of twenty and studied extensively with several teachers. According to his uncle's advice he went to meet the great scholar Khyungpo Tsültrim Gönpo and received the practices of Clear Light, Dream Yoga, etc. Shangkarwa received empowerments from Buton Rinchen Drub (1290-1364) who transmitted to him his wisdom mind stream. In all Shangkarwa received more than twenty times various tantric commentaries. From the great teacher Jangchub Tsemo he received the four complete empowerments of Guhyasamaja. Unfortunately Lama Tsultrim Gön passed away before Shangkarwa could receive the entire Shangpa lineage teachings from him. Shangkarwa then met and received from Ritrö Rechen Sangye Senge the entire cycle of teachings of the Shangpa lineage and entrusted him with responsibility for the lineage. Shangkarwa mastered the Clear Light and Dream Yoga and his realizations where powerful enough to control even the external elements. Shangkarwa passed away at the age of eighty-two with numerous auspicious signs.
