楞伽阿跋多羅寶經註解 3.35

3.35

佛告大慧：「以四等故，如來、應供、等正覺於大眾中唱如是言：『我爾時作拘留孫、拘那含牟尼、迦葉佛。』云何四等？謂字等、語等、法等、身等，是名四等。以四種等故，如來、應供、等正覺於大眾中唱如是言。」

The Buddha told Mahāmati: "Because of four equalities, the Tathāgata, Arhat, Samyaksambuddha proclaims in the great assembly such words: 'At that time I was Krakucchanda, Kanakamuni, and Kāśyapa Buddha.' What are the four equalities? They are equality of syllables, equality of words, equality of dharmas, and equality of bodies. These are called the four equalities. Because of these four kinds of equality, the Tathāgata, Arhat, Samyaksambuddha proclaims such words in the great assembly."
