大般涅槃經集解 36.53

36.53

案僧宗曰：第五就名字為難。若依正義釋無量者，正以緣無量眾生為境。假為不達之辭，乃謬取佛意，謂心體無邊際若稱無量，則不翅有四；若存其少，近應一也。

Sengzong states: The fifth objection challenges based on name and meaning. If one explains 'immeasurable' according to the correct principle, it is precisely taking immeasurable sentient beings as its object. Adopting the guise of an uncomprehending argument, it errantly misconstrues the Buddha's intent, asserting that if the essence of mind is boundless and thus termed immeasurable, then there are more than four; while if one reduces them to a minimum, there should merely be one.
