7.15.57

ādāvante janānāṃ sadbahirantaḥ parāvaram /
jñānaṃ jñeyaṃ vaco vācyaṃ tamo jyotistvayaṃ svayam //

57. For, whatever exists before the bodies were produced and after the bodies are destroyed, in and out of them, what is high and low, or darkness and light, knowledge and the known, or the word and the thing denoted by it—everything is Himself.
