MahayanaMahāyāna (महायान, ˌmɑːhəˈjɑːnə ; Great Vehicle) is a term for a broad group of Buddhist traditions, texts, philosophies, and practices. Mahāyāna Buddhism developed in ancient India (1st century BCE onwards) and is considered one of the three main existing branches of Buddhism, the other being Theravāda and Vajrayāna. Mahāyāna accepts the main scriptures and teachings of early Buddhism but also recognizes various doctrines and texts that are not accepted by Theravada Buddhism as original.
Śāntarakṣita(Sanskrit: शान्तरक्षित; , 725–788), whose name translates into English as "protected by the One who is at peace" was an important and influential Indian Buddhist philosopher, particularly for the Tibetan Buddhist tradition. Śāntarakṣita was a philosopher of the Madhyamaka school who studied at Nalanda monastery under Jñānagarbha, and became the founder of Samye, the first Buddhist monastery in Tibet. Śāntarakṣita defended a synthetic philosophy which combined Madhyamaka, Yogācāra and the logico-epistemology of Dharmakirti into a novel Madhyamaka philosophical system.
Two truths doctrineThe Buddhist doctrine of the two truths (Sanskrit: dvasatya, ) differentiates between two levels of satya (Sanskrit; Pali: sacca; word meaning "truth" or "reality") in the teaching of the Śākyamuni Buddha: the "conventional" or "provisional" (saṁvṛti) truth, and the "ultimate" (paramārtha) truth. The exact meaning varies between the various Buddhist schools and traditions. The best known interpretation is from the Madhyamaka school of Mahāyāna Buddhism, whose founder was the Indian Buddhist monk and philosopher Nāgārjuna.
Buddhist logico-epistemologyBuddhist logico-epistemology is a term used in Western scholarship to describe Buddhist systems of (doctrine of proof) and hetu-vidya (science of causes). is an epistemological study of the nature of knowledge; Hetu-vidya is a system of logic. These models developed in India during the 5th through 7th centuries. The early Buddhist texts show that the historical Buddha was familiar with certain rules of reasoning used for debating purposes and made use of these against his opponents.
