Aśvaghoṣa (?80-?150 CE) (Devanagari: अश्वघोष) was an Indian philosopher-poet, born in Saketa in northern India to a Brahmin family. He is believed to have been the first Sanskrit dramatist, and is considered the greatest Indian poet prior to Kālidāsa. He was the most famous in a group of Buddhist court writers, whose epics rivaled the contemporary Ramayana. Whereas much of Buddhist literature prior to the time of Aśvaghoṣa had been composed in Buddhist Hybrid Sanskrit, Aśvaghoṣa wrote in Classical Sanskrit.

According to the traditional biography of Aśvaghoṣa, which was translated into Chinese by Kumārajīva, and preserved in that language, he was originally a wandering ascetic who was able to defeat all-comers in debate.

He set a challenge to the Buddhist monks that if none could meet with him in debate then they should stop beating the wood-block which signalled to the people to bring offerings to them. There was no one there to meet the challenge so they stopped beating the wood-block.

However, in the north there was an elder bhikṣu named Pārśva at the time, who saw that if he could convert this ascetic, it would be a great asset to the propagation of the Dharma, so he traveled from northern India, and had the wood-block sounded.
