Paṇchen Namkha Pelzang
In particular, he received the complete Kālacakra initiation, explanation of the Kālacakra Tantra, and the esoteric instructions of the Jonang tradition from Namkha Chokyong (nam mkha' chos skyong, 1436-1507), who was the eighteenth abbot of Jonang Monastery.
According to the hagiographies, when Namkha Pelzang practiced the six-branch yoga of Kālacakra he gained unimpeded clairvoyance, and, when the ten vital winds were drawn into the central channel during meditation, a great experience of bliss erupted and the ten signs of clear light and other indications of accomplishment became stable.
Namkha Pelzang founded the monastery of Drepung ('bras spungs, not to be confused with the great Geluk monastery of the same name), where he continuously taught the six-branch yoga to many male and female practitioners.
In the monasteries of Lega (sle ga), Drepung, and Lhundrub Ding (lhun grub sdings) Namkha Pelzang gave the Kālacakra initiation, the explanation of the Kālacakra Tantra, and the esoteric instructions of the six-branch yoga to many thousands of ordained and lay men and women.
Namkha Pelzang also transmitted the collected writings of the Dolpopa Sherab Gyeltsen (dol po pa shes rab rgyal mtshan, 1295-1361), the tantric traditions of Cakrasaṃvara, Hevajra, Guhyasamāja, Vajrabhairava, the Six Dharmas of Niguma, the teachings of Machik Labdron (ma gcig lab sgron, 1055-1149), Mind Training (blo sbyong), and so forth.
When he passed away, many marvelous signs are said to have occurred, and heaps of relics were found in his remains. Namkha Pelzang had many disciples, such as Lochen Ratnabhadra (lo chen ratna bha dra, 1489-1563) and the great expert Sherab Tashi (shes rab bkra shis, d.u.).
