3.41

First: internal emptiness. Internal emptiness means that internal dharmas are empty. Internal dharmas are the so-called six internal āyatanas: eye, ear, nose, tongue, body, and mind. The eye is empty of self and of what belongs to self. The non-existence of eye, ear, nose, tongue, body, and mind is also like this; this is internal emptiness.
