When Katyayana’s uncle, Asita was about to die, he asked Katyayana to renounce and follow the Buddha. However, the scholarly and knowledgeable Katyayana was arrogant and ignored his uncle’s last wish. He only turned to the Buddha when he was baffled by some mysterious inscriptions. After renouncing, he practiced diligently and became skilled in analyzing the Dharma and debating. He once taught a poor elderly woman to avoid poverty by practicing generosity and utilized his wisdom to stop King Virudhaka from killing monks. Katyayana was foremost in debating among the Buddha’s disciples.
