大般涅槃經集解 49.22

49.22

案僧亮曰：得異耳根者，有三事異：一者下地聞上地、二遠及恒沙、三耳識不取相，是不聞而聞。初無音聲相者，菩薩耳識真俗兼見，故不取相。

Sengliang states: Regarding the attainment of a distinct auditory faculty, there are three distinct features: first, hearing the higher stages from a lower stage; second, extending far to Ganges sands; third, the auditory consciousness not grasping at signs, which is hearing without hearing. As for initially having no signs of sound, the bodhisattva's auditory consciousness perceives both the ultimate and conventional simultaneously, and therefore does not grasp at signs.
