Chapter 24 - The rwa tradition

Now (here is an account) of (the school) which is known as the tradition of rwa of Śrī-Kālacakra: The ācārya tsi lu pa having first obtained the Kālacakra, his disciple was bsod snyoms pa (Piṇḍo);the latter’s disciple was Kālacakrapāda, the Senior (dus zhabs pa che ba); the latter’s disciple- Kālacakrapāda, the Junior (dus zhabs pa chung ba); the latter’s disciple Mañjukīrti; the latter’s disciple—the paṇḍita Samantaśrī of ye rang in Nepāl.

Rwa lo tsā ba rdo rje brags pa’s nephew, named rwa chos rab was very learned in the Tantra class. He especially mastered the doctrines possessed by rwa rdo rje grags pa, invited to Tibet the paṇḍita Samantaśrī, and (assisted by him) made a good translation of the Kālacakra-Tantra together with its Commentary—the Vimalaprabhā, and listened to its exposition. He also translated many branches of the Kālacakra, pleased the paṇḍita with his offerings, and escorted him as far as Nepāl. The paṇḍita was pleased and presented him the hat of 'bum phrag gsum pa.^[1] Having gone to dbus, he laboured extensively for the welfare of numerous inhabitants of khams and dbus.

He preached the doctrines, especially the Kālacakra, to rwa ye shes seng ge. The latter taught it to rwa 'bum seng, who (taught it) to the Venerable rgwa lo (tsā ba).
