Chandragomin (Skt. Candragomin) was a renowned 7th century CE Indian Buddhist lay master and scholar who dressed in the white robes of the Yogic tradition and mastered the morality of the five precepts.
He was most famous for his debate of Candrakīrti (600–c. 650), (Devanagari: चन्द्रकीर्ति, Tib. Dawa Drakpa) the Arya Tripitaka Master Shramana who was the Khenpo at Mahāvihāra Monastery. Their debate was said to have gone on for many years. Chandragomin held the Chittamatra (consciousness-only or Yogachara school) view, and Chandrakirti gave his interpretation of Nāgārjuna's view, eventually creating a new school of Madhyamaka known as Prasangika. This Nalanda tradition school is know as Prāsaṅgika Madhyamaka or rendered in English as the “Consequentialist” or “Dialecticist” school.
