तावत्सर्वं सत्यमिवाभाति यदेत-द्यावत्सोऽस्मीत्यात्मनि यो ज्ञो न हि दृष्टः ।दृष्टे यस्मिन्सर्वमसत्यं भवतीदंतं संसारध्वान्तविनाशं हरिमीडे ॥ ४० ॥
In plain words
All of this looks real — and it goes on looking real for exactly as long as you have not yet seen, within yourself, the one who knows: I am That. The moment he is seen, none of this is real any longer. Hari, the ending of the darkness that is saṃsāra — him I praise.
Close to the Sanskrit
Only so long does all this, which is here, shine as if real, as long as that knower in the self — 'I am He' — is indeed not seen; and when he is seen, all this becomes unreal. Him, the destruction of the darkness of saṃsāra, Hari, I praise.
