首楞嚴義疏注經 1.64

1.64

具云奢利弗怛囉，此云鶖子。其人母眼黑白分明，轉動流利，從彼所生，連母為號，亦云身子，是佛右面弟子。慧解過人，故云大智。《增一》云「我佛法中，智慧無雙、決了諸疑者，舍利弗第一。」

Fully called Śāriputra, translated here as "Son of the Egret." The mother of this person had eyes with clearly distinct black and white, rolling and flowing smoothly; born of her, he took his appellation from his mother; he is also called "Body-Son." He was the disciple at the Buddha's right side. His wisdom and understanding surpassed other men, hence he is called "Great Wisdom." The Ekottarika-āgama says: "Within my Buddhadharma, the one foremost in wisdom beyond peer and in resolving all doubts is Śāriputra."
