The works of Ādi Śaṅkarācārya

Aparokṣānubhūtiḥ

Verse 137

अनेनैव प्रकारेण वृत्तिर्ब्रह्मात्मिका भवेत् ।उदेति शुद्धचित्तानां वृत्तिज्ञानं ततः परम् ॥ १३७ ॥

In plain words

Practised in just this way, the mind's every turning takes the form of Brahman and nothing else. And in a mind made pure, something further dawns: a knowing higher than any knowing the mind can hold as a thought.

Close to the Sanskrit

By this very method the mental modification (vṛtti) would become of the nature of Brahman. For those of purified mind there rises up a knowledge higher than that knowledge borne by the modification.
