अहं ब्रह्मेति विज्ञानात्कल्पकोटिशतार्जितम् ।सञ्चितं विलयं याति प्रबोधात्स्वप्नकर्मवत् ॥ ४४८ ॥
In plain words
The instant the realization 'I am Brahman' dawns, karma piled up across a billion world-ages simply dissolves away — the way everything you did in a dream vanishes the moment you wake up.
Close to the Sanskrit
From the realization 'I am Brahman', accumulated karma gathered over a billion world-ages dissolves — like the deeds of a dream upon awakening.
