12.5.8

na tatrātmā svayaṃ-jyotir yo vyaktāvyaktayoḥ paraḥ /
ākāśa iva cādhāro dhruvo 'nantopamas tataḥ //

8. There (in that combination) Atman does not perish; for He is a light Himself and distinct from the subtle and gross universe He is the support, like the sky, of every thing, subject to no change

and is without limits or another like him, (without a second) hence He is Omnipresent.
