Geshe Ngawang Kalsang, later known as Domo Geshe Rinpoche, is said to have been Shariputra, the Mahadsiddha Gayadhara, Dharmashri, Munijnana, Tönmi Sambhota, King Trisong Detsen, Dromtönpa, Milarepa, Khedrup Rinpoche, and Dragpa Gyaltsen in previous lives.
At the age of 8 he received the name Ngawang Kalsang, upon entering Tashi Lhunpo Monastery. After 20 years of study he received the “kachen” degree, Tashi Lhunpo’s equivalent of the “geshe” degree.
Later, he left the monastery and meditated for 12 years in various caves and retreats in the mountain wilderness of Southern Tibet. One day a lost herdsman discovered him in retreat in a cave, and brought word back to the people of the valley. They requested him to settle among them and teach, and he did so. From the book The Way of the White Clouds, written by a Western student of the lama:
There was a very small and poor monastery in the valley from which the people had come, situated on a steep hill with a rocky crest in the middle of a fertile wheat growing valley called Domo (wheat). This place was given to the Hermit-Lama, who from then on was known as Domo Geshe Rinpoche, 'The Learned Jewel of the Wheat Valley'.
Upon request by the people of Domo to stay with them, Geshe Rinpoche rebuilt Dungkar Gonpa (White Conch Monastery). It was so named after several white conch manifestations there. He enlarged the main Buddha statue of the monastery and built a Maitreya Buddha statue, as a symbol of the spiritual future. During his travels in India, he was entrusted with several more monasteries. A patron from Darjeeling offered him a retreat house at Ghoom Yiga Chöling Monastery and requested him to take care of the monastery. Rinpoche enlarged it and built another famous two-storey Maitreya Buddha statue. In 1919 Tashi Chöling Monastery in Kurseong, near Darjeeling, was completed and consecrated by Geshe Rinpoche, and Tharpa Chöling Monastery in Kalimpong was finished in 1922.
Domo Geshe Rinpoche was the first of the Tibetan lamas to go on pilgrimage repeatedly to the Buddhist holy sites in India. It was on one of these pilgrimages that he had his most well-known vision:
