न ह्यस्ति विश्वं परतत्त्वबोधा -त्सदात्मनि ब्रह्मणि निर्विकल्पे ।कालत्रये नाप्यहिरीक्षितो गुणेन ह्यम्बुबिन्दुर्मृगतृष्णिकायाम् ॥ ४०५ ॥
In plain words
Once the supreme Truth is known, the universe simply isn't there — not in the past, not now, not ever — inside the Self that is Being itself, inside Brahman beyond every distinction. It's exactly like the snake that was never really in the rope, or the drop of water that was never really in the mirage.
Close to the Sanskrit
The universe indeed does not exist, once the supreme Truth is known, in the existent Self, the thought-free Brahman — at any of the three times — just as a snake is never really seen in a rope, and just as there is no drop of water in a mirage.
