Nāgasena

Nāgasena was an Indian sage and a prominent Buddhist monk who engaged in a lively dialogue with King Milinda (Menander), a Greek ruler of an Indo-Greek empire in the late 2nd century BCE. Their discussions, recorded in the Milinda-panha (The Questions of Milinda), explore various Buddhist doctrines and philosophical dilemmas. Nāgasena's explanations, often using parables, address fundamental questions about the nature of the self and Buddhist teachings. The Milinda-panha is considered an authoritative, though noncanonical, work within the Theravada school of Buddhism.12
