18.89

案道生曰：共所安故，是為一家也。僧亮曰：凡夫譬小，二乘譬大也。法瑤曰：眾生萬品不同，為大小也。同居累內，為家人也。俱迷於理，為無有知者也。曇濟曰：身有優劣，為大小也。僧宗曰：聞慧為小，脩慧為大也。寶亮曰：曠舉六道不知，故言小大也。智秀曰：佛法一家之中，凡是學人，佛未說故，謂不知也。

Daosheng states: Because they dwell together in safety, they are 'one household'. Sengliang states: Ordinary beings are compared to the young; the two vehicles are compared to the old. Fayao states: The myriad varieties of sentient beings being dissimilar constitutes 'old and young'. Residing together within defilements constitutes 'the household'. Being universally deluded regarding the principle constitutes 'none was aware'. Tanji states: The body having superior and inferior constitutes 'old and young'. Sengzong states: Wisdom from hearing is the young; wisdom from cultivation is the old. Baoliang states: Broadly citing that none in the six destinies knows, it therefore says 'old and young'. Zhixiu states: Within the single household of the Buddha-Dharma, all who are trainees, because the Buddha had not yet spoken of it, are called 'unaware'.
