The biography of Kumārajīva describes how he displayed his talent even when he was still in his mother’s womb. It is said that after his mother conceived him, the wisdom of Kumārajīva was so highly effective that he even influenced his mother, with which she became very knowledgeable, and her understanding ability was doubled than before. In addition, she was able to speak Sanskrit language without ever having learned it before, and was extremely fluent in being engaged in debate. (Page 10)
