Verse 1.12

नाऽऽत्मानं न परंश्चैव न सत्यं नापि चानृतम् ।
प्राज्ञः किंचन संवेत्ति तुर्यं तत्सर्वदृक्सदा ॥ १२ ॥

nā''tmānaṃ na paraṃścaiva na satyaṃ nāpi cānṛtam |
prājñaḥ kiṃcana saṃvetti turyaṃ tatsarvadṛksadā || 12 ||

The ‘prājñaḥ’ one who is in deep sleep does not know itself as an Atman..! It doesnot know the world (prapanch) also .. It doesnot know the truth that I am “Turiya”. It doesnot know the false world appearing infront of it (ānṛtam) चानृतम्.

किंचन संवेत्ति / prājñaḥ kiṃcana saṃvetti – The ‘prājñaḥ’ doesnot know anything i.e the state of deep sleeper !!.

and ,

How is Turiya different from It??? the answer is – तुर्यं तत्सर्वदृक्सदा /turyaṃ tatsarvadṛksadā

i.e. It (Turiya) always illumines everything ! It is self illumined about itself and about the world . It is like the movie hall where the lights have come on with nothing on the screen …( blank screen) but the lights are on !
