philosopher and poet who is considered India's greatest poet before Kālidāsa (5th century) and the father of Sanskrit drama; he popularized the style of Sanskrit poetry known as kāvya (kavya).

Aśvaghoṣa was born a Brahman. Legend obscures the man, but it is known that he was an outspoken opponent of Buddhism until, after a heated debate with a noted Buddhist scholar on the relative merits of the Vedāntic (Hindu) religion and the middle path (Buddhism), he accepted the value of Buddhism and became a disciple of his erstwhile opponent.

While in Vārānasi (Benares), where Gautama Buddha had preached his first sermon, Aśvaghoṣa saw the city conquered by the Kushan (Kuṣāṇa) emperor Kaniṣka (Kaniska), a devout Buddhist. A huge war indemnity was demanded, and the ruler of Vārānasi handed over instead a symbolic tribute, a begging bowl said to have been used by both the Buddha and Aśvaghoṣa. Apparently the philosopher rose to the position of spiritual counsellor in Kaniṣka's court at Peshāwar.

A brilliant orator, Aśvaghoṣa spoke at length on Mahāyāna (Mahayana) (Greater Vehicle) Buddhist doctrine at the fourth Buddhist council, which he helped organize. His fame lay largely in his ability to explain the intricate concepts of Mahāyāna Buddhism. Among the works attributed to him are the Mahāyāna-śraddhotpāda-śāstra (“The Awakening of Faith in the Mahāyāna”), the Buddhacarita (“The Life of Buddha”) in verse, and the Mahālaṅkara (“Book of Glory”).
