Dharmaraksita and Punabbasukutumbikaputta Tissa Thera
In another Pali reference, a Buddhist monk from Sri Lanka named Punabbasukutumbikaputta Tissa Thera is said to have been to India in order to study with "the Yonaka Dhammarakkhita", whereupon he attained the "patisambhida" (analytical knowledge). (VibhA.389, Sammoha-Vinodaní, Vibhanga Commentary).
The place where Dharmaraksita resides is also said to be around 100 leagues (around 700 miles) from Sri Lanka, putting it somewhere in northern India. (See: )
