प्रत्यग्विमर्शातिशयेन पुंसां प्राचीनगन्धेषु पलायितेषु ।प्रादुर्भवेत्काचिदजाड्यनिद्रा प्रपञ्चचिन्तां परिवर्जयन्ती ॥ २४ ॥
In plain words
When looking inward grows so overwhelming that the old traces of a whole past simply take flight, something dawns in a person that has no name: a sleep with no dullness anywhere in it, letting go of every thought of this spread-out world as it comes.
Close to the Sanskrit
By the surpassing abundance of inward reflection on the Self, in persons — the ancient traces having fled — there may come forth some indescribable sleep without dullness, casting away all thought of the manifold world.
