Buddhist logico-epistemology in the context of Dignāga

Buddhist philosophy is the ancient Indian philosophical system that developed within the religio-philosophical tradition of Buddhism. It comprises all the philosophical investigations and systems of rational inquiry that developed among various schools of Buddhism in ancient India following the parinirvāṇa of Gautama Buddha (c. 5th century BCE), as well as the further developments which followed the spread of Buddhism throughout Asia.

Buddhism combines both philosophical reasoning and the practice of meditation. The Buddhist religion presents a multitude of Buddhist paths to liberation; and with the expansion of early Buddhism from ancient India to Sri Lanka and subsequently to East Asia and Southeast Asia, Buddhist thinkers have covered topics as varied as cosmology, ethics, epistemology, logic, metaphysics, ontology, phenomenology, the philosophy of mind, the philosophy of time, and soteriology in their analysis of these paths.

Tsongkhapa (Tibetan: ཙོང་ཁ་པ་, [tsoŋˈkʰapa], meaning: "the man from Tsongkha" or "the Man from Onion Valley", c. 1357–1419) was an influential Tibetan Buddhist monk, philosopher and tantric yogi, whose activities led to the formation of the Gelug school of Tibetan Buddhism.

His philosophical works are a grand synthesis of the Buddhist epistemological tradition of Dignāga and Dharmakīrti, the Cittamatra philosophy of the mind, and the madhyamaka philosophy of Nāgārjuna and Candrakīrti.
