'He who dwells in the ear, and within the ear, whom the ear does not know, whose body the ear is, and who pulls (rules) the ear within, he is thy Self, the puller (ruler) within, the immortal.'

In plain words: Yagnavalkya says the same about hearing. Something lives inside the ear and guides it, but the ear does not know it. That inner guide is your Self, which never dies.
