BṚHADĀRAṆYAKA UPANISHAD · 6.1.10

श्रोत्रं होच्चक्राम ।
तत् संवत्सरं प्रोष्यागत्योवाच -- कथम् अशकत मद् ऋते जीवितुम् इति ।
ते होचुः -- यथा बधिरा अशृण्वन्तः श्रोत्रेण प्राणन्तः प्राणेन वदन्तो वाचा पश्यन्तश् चक्षुषा विद्वांसो मनसा प्रजायमाना रेतसैवम् अजीविष्मेति ।
प्रविवेश ह श्रोत्रम् ॥

śrotraṃ hoccakrāma ।
tat saṃvatsaraṃ proṣyāgatyovāca -- katham aśakata mad ṛte jīvitum iti ।
te hocuḥ -- yathā badhirā aśṛṇvantaḥ śrotreṇa prāṇantaḥ prāṇena vadanto vācā paśyantaś cakṣuṣā vidvāṃso manasā prajāyamānā retasaivam ajīviṣmeti ।
praviveśa ha śrotram ॥

The ear (hearing) departed, and having been absent for a year, it came back and said: 'How have you been able to live without me?' They replied: 'Like deaf people, not hearing with the ear, but breathing with the breath, speaking with the tongue, seeing with the eye, knowing with the mind, generating with seed. Thus we have lived.' Then the ear entered in.
