無量壽經連義述文贊 3.51

3.51

經曰「又彼菩薩」至「如我國也」者，述云：此第如是四反，積地四寸也。凞，怡，《說文》「和悅也」，《方言》「怡喜也」。

On the sūtra's words from "Moreover, those bodhisattvas" to "like my land," the Commentary states: This is repeated four times like this, accumulating four inches on the ground. Xi [凞] means yi [怡]. The Shuowen says: "Harmonious and pleased." The Fangyan says: "Pleased and joyous."
