【摩訶拘絺（丑夷）羅】《大論》云：「秦言大膝。摩陀羅次生一子，膝骨麁大，故名拘絺羅。舍利弗舅，與姊舍利，論義不如。俱絺羅思惟念言：『非姊力也，必懷智人。寄言母口，未生乃爾，及生長大，當如之何？』故出家作梵志，入南天竺，誓不剪爪，讀十八種經。」

[Mahā-kauṣṭhila] The Dazhidu lun says: 'In Qin speech, it means Big Knee. Māṭhara subsequently gave birth to a son whose knee bones were coarse and large, hence he was named Kauṣṭhila. He was the maternal uncle of Śāriputra. When debating with his sister Śāri, he was not her equal. Kauṣṭhila contemplated and thought: "This is not my sister's own ability; she must be carrying a wise person. She borrows speech through the mother's mouth. If it is already like this before birth, how will it be when he is born and grown up?" Therefore he renounced household life to become a brahmacārin, entered Southern India, vowed not to cut his nails, and studied the eighteen classes of scriptures.'
