Masters of the Golden Rosary Lineage: Life and Liberation of Drigung Kagyü Throne-holders:
17th Drigungpa, Gyalwang Rinchen Püntsok
(1509-1557, r. 1528-1534)

THE 17th Drigungpa was the nephew of Gyalwang Künga Rinchen. Even before the boy was born, Künga Rinchen had announced that he is a reincarnation of the Indian
mahāsiddha Hūṃkaravajra. Unfortunately, when he was only five years old, the lay leaders of Drigung made the accusation that the child might not be of the Kyura clan. Eventually, Gyalwang Rinchen Püntsok left with some attendants to the Yarlung region where the King of Neudong welcomed them. He was exceptionally intelligent and a fast-learner. Even while just a child he was able to memorize texts like the Cakrasamvara Sādhana, Chenrezig Sādhana, Guru Yoga and Five-fold Path of Mahāmudrā. During this time, Gyalwang Rinchen Püntsok also traveled to Tashi Dowoka and received all the lineage teachings of Drigung-til and Densa-til from Khenchen Sonam Tashi and the complete texts of Cakrasamvara from the tradition of Ghantapada, Four-Armed Mahākāla, "Songs of Milarepa" and complete collected-works of Gampopa, Pakmo Drupa, Jikten Sumgön and other Drigung masters. He also received teachings on
The Single Intention, Amitayus (Siddharajni tradition) and Gyalwang Yangonpa’s (1213-1258)
Mountain Dharma (a definitive manual for retreats). Furthermore, at Densa-til, the Fourth Red Hat (Zhamar) Karmapa, Chökyi Drakpa (1453-1526), gave him the vows and the name Rinchen Püntsok. The Zhamarpa also gave Rinchen Püntsok transmission and oral instructions of "The Three Cycles of Jewels of the Hearing Lineage" as well as transmission of the 100,000 New Tantras (
Sarma Gyübum). During this time he also memorized Hevajra root-texts and familiarized himself with Hevajra commentaries.
At the Zhamarpa’s Yangpachen Monastery, Rinchen Püntsok further received from him the Kalacakra teachings and completion-stage teachings of Cakrasamvara, Guhyasamaja and Hevajra. The Zhamarpa also imparted to Rinchen Püntsok teachings unique to the Drigung lineage. Furthermore, Rinchen Püntsok also received transmissions on the texts of the different Karmapas and Zhamarpas. While at Yangpachen, Rinchen Püntsok especially familiarized himself with
The Five Dharmas of Maitreya. While in retreat at the Gura Cave, Rinchen Püntsok realized the oneness of the outer and inner states.
In 1525, Rinchen Püntsok finally returned to Drigung-til. His uncle, Gyalwang Künga Rinchen, gave him many Drigung transmissions. When he received instructions on Mogu Sogkor there were clear signs of success and when he received Five-fold Path of Mahāmudrā teachings he attained actualization. In accordance with the established tradition at Drigung, Rinchen Püntsok practiced Six Dharmas of Nāropa clad only in a white cotton shawl.
In 1527 Gyalwang Künga Rinchen departed for the pure Buddha-realms. During the ten days of funeral rites led by Rinchen Püntsok, rainbows emanated from Künga Rinchen’s heart and dissolved into the heart of Rinchen Püntsok. Thereafter, Rinchen Püntsok received full-ordination as a monk from Khenchen Drakpa Gyeltsen, went into a retreat to focus on Achi practice and subsequently received the signs of protection from her. In 1528, Rinchen Püntsok emerged from retreat and became the 17th throne-holder of Drigung.
As the throne-holder, Rinchen Püntsok’s public teachings followed the old tradition: Five-fold Path of Mahāmudrā in the summer and Six Dharmas of Nāropa in the winter. He also sent disciples to the traditional retreat places of Lapchi, Kailash and Tsari. According to certain prophecies, Rinchen Püntsok’s life could only be stable if he did not cut his hair. But under the pressure of the monastic community, Rinchen Püntsok cut his hair despite the prophecies. Not long after, he received a vision of Guru Rinpoché who advised him to have the entire Kangyur recited, to hold a hundred feast-offerings of Vajravarahi and to make prayers to the Dharma-protectors. Guru Rinpoché repeated the advice that he kept his hair long. Immediately after this vision, Rinchen Püntsok withdrew himself to Terdrom to do as Guru Rinpoch instructed. While at Terdrom, Rinchen Püntsok reopened the sacred cave of Kiri Yangdzong - a cave first discovered by the Tenth Drigungpa, Dorjé Gyelpo.
In 1534, Rinchen Püntsok stepped down from the throne and transferred it to his cousin's son Rinchen Namgyel (1519-1576). From that point on he was free to allow his hair grow long and remain in retreat.
Later, recognizing the importance of the monastic Sangha, Rinchen Püntsok established Yangri Gar Monastery nearby Yamari Monastery. He gave many teachings at different monasteries in order to fundraise for this project. He also consecrated the soil of many future monasteries with ritual dances he had perceived in a vision of Guru Rinpoché’s pure land. In the ninth month of 1538 Rinchen Püntsok went to Terdrom and at Yangdzong Namkhé Phuk discovered the
terma known as the
Gongpa Yangzab on the 25th day of the lunar calendar (ḍākinī day). After retrieving the
terma, Rinchen Püntsok went to Katsel Monastery and while there focused on editing and arranging the texts as well as renovating Katsel. He completed editing the
Yangzab texts in 1542. In 1546, he married Rigdzin Butri and a son was born to them (Chögyal Püntsok, eventually the 21st Drigungpa) .
Although already an accomplished master, Rinchen Püntsok continued to visit with and receive teachings from other teachers (especially Nyingma masters). At Samyé Monastery he met the famous Nyingma master Ngari Panchen Pema Wangyel (1487-1542) and received from him many teachings of the Nyingma lineage. Gyama Migyur Künga imparted the Mahāyoga Kagyed (
Eight Pronouncements) and the Ātiyoga Nyingthik Yabzhi to him while Rigdzin Düdjom Dorjé gave him the Kagyed teachings from the Nyang tradition as well as Lama Gongdü teachings (revealed by Sangyé Lingpa [1340-1396]). Rinchen Püntsok was also responsible for starting the maṇḍala-rituals of Cakrasamvara, Hevajra, Guhyasamaja, Kalacakra and Kunzang Gongdü (
terma discovered by Pema Lingpa [1450-1521]) at Drigung-til.
In 1557 Rinchen Püntsok unexpectedly left the Drigung area and went to Gyama, the birthplace of King Songtsen Gampo (605?-650?). There, he wrote his spiritual testament and dissolved his body maṇḍala in the fifth month. It was his wish that his death be kept secret for three years and so peace prevailed in the area since many of those who would otherwise cause troubles were kept in line by the threat of his great powers. Three years later his mummified body was brought back to Drigung-til and placed in a stupa with elaborate ceremonies. Later, the stupa was moved to Khangsar Yangon where he once had been in retreat. Some of his relics were also brought to Katsel Monastery where a stupa was built to enshrine them.
As a
terton the great 17th Drigungpa was known under the name of Sengé Namchak Mebar. Gyalwang Rinchen Püntsok had many disciples. Among the most important were Drungpa Rinchen Pel, Lhochen Püntsok Namgyel, Lama Chökyong Rinchen, Tokden Dorjé Pelbar, Tokden Künga Sherap and Tokden Khetsun Drakpa Tsültrim.
