大般涅槃經義記 2.112

2.112

第四段中，「彼大長者畜養此牛但為醍醐」，遠尋聖意；「我等」已下學佛求常；「夫醍醐」下嘆其所求。

In the fourth section, "that great elder raised these cows solely for the sake of ghee" traces back to the sage's intent; "we..." onwards represents studying the Buddha to seek eternity; "now, ghee..." onwards praises what is sought.
