Chandragomin (Skt. Candragomin, Tib. ཙནྡྲ་གོ་མིན་) (seventh century) — 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.
The path followed and taught by the Buddha in order to guide the world
Is within the reach of human beings with strength of heart,
But cannot be attained by the gods, nagas,
Asuras, garudas, vidyadharas, kinnaras or uragas.
