US-P18.210ab तद्विज्ञानाय युक्त्यादि कर्तव्यं श्रुतिरब्रवीत् ।US-P18.210cd कर्तृत्वाद्यनुवादेन सिद्धत्वानुभयाय तु ॥
In plain words
The Upanishads declare that logical inquiry and other disciplines must be practiced to know that reality directly—not to create something new, but to reveal the self already present, starting from the everyday assumption of agency.
Close to the Sanskrit
The scripture has stated that reasoning and other means are to be undertaken for the direct knowledge of that, indeed for the realization of the already established reality by addressing agency and other attributes.
