Chandragomin
Chandragomin - a famous Indian master and scholar who was a lay practitioner, or upasaka, who dressed in white robes and upheld the five precepts (not to kill, steal, commit sexual misconduct or take intoxicants) and famously challenged Chandrakirti to a debate in Nalanda that lasted for many years. His writings include Twenty Verses on the Bodhisattva Vow and Letter to a Disciple.
