Annapurna Upanishad

 IV-28-29. The sage fulfils his duty with the realization, 'I am the one Brahman';

(Brahman is) the ground of all, non-dual, supreme, eternal, of the essence of
being, intelligence, and bliss, beyond the range of word and mind.

IV-30. There shine not the forms of the moon and the sun; the winds blow not;
and none of the gods (are there). This divinity alone shines forth as being, pure
by itself, free from rajas.
