12.4.21

na svapna-jāgran na ca tat suṣuptaṃ na khaṃ jalaṃ bhūr anilo 'gnir arkaḥ /
saṃsupta-vac chūnya-vad apratarkyaṃ tan mūla-bhūtaṃ padam āmananti //

20. & 21. It is not within the range of words or the mind, nor within the sphere of Satva, Rajas and Tamas or Mahat and other principles, nor within the scope of Prana (breath), Buddhi (reason) the senses, and their ruling deities, and nor in the form of the world; it is not affected by the states of dream, wakefulness and sleep; it is neither sky nor water nor earth, nor the air, nor fire nor the sun; it is something like that which is in deep sleep, or nonentity itself, and they say it is the thing which is at the root of everything.
