The eighteenth of Shakyamuni's twenty-three, or the nineteenth of his twenty-four, successors.
According to A History of the Buddha's Successors, he was born in Takshashilain the north-western part of ancient India and was very wise even as a child. He became a monk and is said to have later inherited Shakyamuni Buddha's teachings from Samghayashas.
His wisdom and scholarship were famed throughout India and attracted numerous people to Buddhism. Hsüan-tsang's Record of the Western Regions lists Kumarata as one of the "four suns," the others being Ashvaghosha, Nagarjuna, and Aryadeva.
Kumarata is regarded as the founder of the Sautrantika school. He transferred the Buddha's teachings to Jayata. It is said that he lived near the late third century, but there is no clear evidence confirming that date.
