Candrakīrti

Candrakīrti was a significant Buddhist scholar and philosopher of the Madhyamaka school, active around the 7th century CE. He is primarily known for his profound commentaries on the works of Nagarjuna, the founder of the Madhyamaka school, and Aryadeva, Nagarjuna's main disciple. Candrakīrti's philosophical contributions were particularly influential in Tibet, where he is regarded as the principal exponent of the Prāsaṅgika sub-school of Madhyamaka.

Life and Historical Context

Very little is definitively known about Candrakīrti's life. Tibetan sources suggest he was born in South India and that he became a Buddhist monk. He is said to have studied under Kamalabuddhi, who was a student of Buddhapalita. Candrakīrti was active at the renowned Nalanda monastery in India, where he is reported to have served as abbot. According to Tibetan traditions, he also returned to South India later in his life, engaging in efforts to convert non-Buddhists. A notable event in his life was a famous debate at Nalanda with the grammarian and lay scholar Candragomin, which reportedly lasted seven years. The outcome of this debate and the exact winner are not definitively recorded.

Philosophical Contributions

Candrakīrti's philosophy centers on the Madhyamaka doctrine of emptiness (śūnyatā), which posits that all phenomena lack intrinsic existence (svabhāva). He defended and elaborated upon Nagarjuna's teachings, emphasizing the apophatic method, which involves a thorough negation of all conceptualizations and views. For Candrakīrti, even conventional reality, while appearing real, is ultimately empty of inherent nature and is merely a conceptual construct or dependent designation. He articulated a sophisticated theory of two truths: conventional truth (saṁvṛti satya), which pertains to the everyday world and ordinary experience, and ultimate truth (paramārtha satya), which is the realization of emptiness.

Candrakīrti is particularly famous for his development and advocacy of the Prāsaṅga method of reasoning. This method, as opposed to independent syllogistic inference, relies on reductio ad absurdum arguments to demonstrate the logical inconsistencies and absurd consequences of an opponent's philosophical positions. He argued that this consequential reasoning was the most appropriate method for Madhyamaka, as it avoids asserting a positive thesis and instead deconstructs opposing views, aligning with the apophatic nature of the philosophy.

Notable Works and Legacy

Candrakīrti authored two highly influential works that have shaped the study of Madhyamaka philosophy. The Prasannapadā (Clear Words) is a commentary on Nagarjuna's Mūlamadhyamakakārikā (Fundamental Verses on the Middle Way), and the Madhyamakāvatāra (Introduction to the Middle Way) is a comprehensive exposition of Madhyamaka philosophy. While his influence was not widespread in the earlier centuries, by the 11th and 12th centuries, his work gained significant traction in Kashmir and especially in Tibet. Tibetan scholars like Rendawa Zhönnu Lodrö and Tsongkhapa actively promoted Candrakīrti's teachings, solidifying his position as a central figure in Tibetan Buddhist thought and the study of emptiness.
