KAIVALYA UPANISHAD · 21

अपाणिपादोऽहमचिन्त्यशक्तिः पश्याम्यचक्षुः स श‍ृणोम्यकर्णः ।
अहं विजानामि विविक्तरूपो न चास्ति वेत्ता मम चित्सदाऽहम् ॥ २१

apāṇipādo’hamacintyaśaktiḥ paśyāmyacakṣuḥ sa śṛṇomyakarṇaḥ ।
ahaṃ vijānāmi viviktarūpo na cāsti vettā mama citsadā’ham ॥ 21

I have neither hands nor feet. I have power unthinkable. I see without eyes. I hear without ears. I am omniscient. I have one kind of form only. None is able to know Me fully. I am always of the form of Chit.
