Geshe Yungdrung Gyamtso Choekhortshang, brother of Nyima Woser Choekhortshang Rinpoche, was born in 1980 with the name Tsewang Gyaltsen. He spent his childhood alongside his father in the monastery, learning the art of preparing torma for tsog offerings, and Tibetan reading and writing. At the age of nine he received the name Yungdrung Gyatso when he took monastic vows from Yongdzin Tenzin Namdak Rinpoche at Triten Norbutse Monastery in Kathmandu; where he was one of the first monks. At the age of 10, he met his root teacher Yongdzin Tenzin Namdak Rinpoche for the first time, and he began his studies to become a Geshe in 1994 (at age 14).
After his studies in 2009, he completed a one hundred day retreat in the practice of the Tibetan yogas Tsa rLung and Trul Khor. He also worked as director at the Medical School in Dolpo (Nepal) and as editor of the magazine Drepoi Beltam of Triten Norbutse Monastery. He also worked on rebuilding the Tashi Namgyal Monastery in Dolpo, of which his brother Geshe Nyima Woser is the abbot. During those years he traveled to various parts of Europe: Austria, Belgium, France, Germany, Italy, Switzerland, Poland and the Czech and Slovak Republics. Between 2010 and 2011 Geshe Tenzin Wangyal Rinpoche and Geshe Gyamtso met and saw each other. In Berlin in 2013, Tenzin Wangyal Rinpoche asked him if he would like to teach in Europe and remain as a resident lama in Poland.
Since March 2015 he is officially the resident lama of the Chamma Ling Poland retreat center (in Wilga) branch of Ligmincha Poland, and since that year he has been teaching in Warsaw, Sopot, Gdańsk and Krakow (of which his brother Geshe Nyima Woser is its abbot). During those years he traveled to various parts of Europe: Austria, Belgium, France, Germany, Italy, Switzerland, Poland and the Czech and Slovak Republics.
