कानि पुनः तानि —
श्रोत्रं चक्षुः स्पर्शनं च त्वगिन्द्रियं रसनं घ्राणमेव च मनश्च षष्ठं प्रत्येकम् इन्द्रियेण सह, अधिष्ठाय देहस्थः विषयान् शब्दादीन् उपसेवते ॥ ९ ॥
In plain words
But what exactly are they? —
Hearing, sight, and touch, the very organ of the skin, taste, and smell too, and the mind as a sixth: taking hold of each of these one by one, the embodied self, dwelling in the body, tastes its objects, sound and all the rest.
Close to the Sanskrit
What, again, are those? —
The ear, the eye, and touch, and the skin-organ, taste, and smell indeed, and mind, the sixth — with each sense severally — having taken possession, situated in the body, [he] partakes of the objects, sound and the rest. || 9 ||
