金光明經文句記 1.67

1.67

三、《釋論》。彼明耳識從四緣生，一空、二根、三境、四作意。今云不壞是根、可聞處是境、諦聽是作意，唯闕空緣。下云「因緣和合」，義可兼之。即四緣和合方發耳識。不言耳聞稱我聞者，我是耳主故。新云耳識九緣生，備於《唯識》也。

Third, the Treatise (*Mahāprajñāpāramitopadeśa). That [treatise] explains that auditory consciousness arises from four conditions: first, space; second, the faculty; third, the object; and fourth, mental application. Here it says that being unimpaired is the faculty, the audible place is the object, and listening attentively is mental application; only the condition of space is missing. Below it says, "the harmonious combination of causes and conditions," which in meaning can encompass it. Thus, only when the four conditions combine harmoniously is auditory consciousness produced. Not saying "the ear hears" but saying "I have heard" is because the self is the master of the ear. The new [translation] states that auditory consciousness is produced from nine conditions, which is fully set forth in the Vijñaptimātratā.
