The works of Ādi Śaṅkarācārya

Aparokṣānubhūtiḥ

Verse 96

रज्जुरूपे परिज्ञाते सर्पभ्रान्तिर्न तिष्ठति ।अधिष्ठाने तथा ज्ञाते प्रपञ्चः शून्यतां व्रजेत् ॥ ९६ ॥

In plain words

Once you have really seen the rope for what it is, the snake cannot stay. In the same way, once the substratum is known, this whole spread-out world goes to nothing.

Close to the Sanskrit

When the form of the rope is fully known, the snake-delusion does not stand; likewise, when the substratum is known, the manifold world would go to nothingness.
