Nāgārjuna

Nāgārjuna (c. 150–250 CE) was an Indian Buddhist philosopher, monk, and mystic regarded as one of the greatest thinkers in the history of Buddhism. He is the founder of the Madhyamaka (“Middle Way”) school, which emphasizes the realization of śūnyatā (emptiness)—the insight that all phenomena lack inherent, independent existence. Born in South India, likely near modern-day Andhra Pradesh, Nāgārjuna was educated in the Buddhist monastic universities and mastered both logic and the scriptures of the Mahāyāna. His seminal text, the Mūlamadhyamakakārikā (“Fundamental Verses on the Middle Way”), is the cornerstone of Mahāyāna philosophy, systematically demonstrating that all conceptual views—including existence and nonexistence—are self-contradictory when taken as ultimately real.

Nāgārjuna’s genius lay in showing that dependent origination (pratītyasamutpāda) and emptiness (śūnyatā) are not separate doctrines but two ways of expressing the same truth: because all things arise dependently, nothing exists with intrinsic nature. His writings—including Śūnyatāsaptati, Vigrahavyāvartanī, and Ratnāvalī—influenced nearly all later schools of Buddhist philosophy, from Yogācāra to Tibetan Madhyamaka, and even resonated with nondual traditions such as Advaita Vedānta. In Mahāyāna lore, Nāgārjuna is said to have received the Prajñāpāramitā Sūtras from the Nāgas (serpent beings) beneath the ocean, symbolizing his access to profound wisdom hidden from ordinary perception. His vision of the Middle Way continues to inspire philosophers and practitioners alike, uniting rigorous reasoning with the direct realization of the nondual nature of reality.

Placement among Buddhist schools

Nāgārjuna is the foundational figure of the Madhyamaka tradition. His works (especially the Mūlamadhyamakakārikā) systematically critique the tendency of Abhidharma (especially Vaibhāṣika-style) and Sautrāntika philosophies to treat dharmas as ultimately real entities, whether spread across three times or strictly momentary. He also anticipates critiques of Cittamātra insofar as it might reify consciousness or a storehouse mind (ālayavijñāna) as ultimately existent.

In the doxographical grid of Vaibhāṣika / Sautrāntika / Cittamātra / Madhyamaka, Nāgārjuna is squarely Madhyamaka: he accepts Abhidharma analysis as conventionally useful but denies ultimate intrinsic existence (svabhāva) to all dharmas, including both external objects and mind.
