US-P18.197ab तस्मादाद्यन्तमध्येषु कुर्वित्येतद् विरोध्यतः ।US-P18.197cd न कल्प्यमश्रुतत्वाच् च श्रुतत्यागोऽप्यनर्थकः ॥
In plain words
So the command "act!" — whether at the beginning, at the end, or in the middle — contradicts this teaching. There is no assuming it into the text: śruti never says it. And discarding what śruti does say serves no purpose either.
Close to the Sanskrit
Therefore, with regard to the beginning, the end and the middle, this [injunction] 'act!' is contradictory; hence it is not to be assumed, and because it is not stated [in śruti]; and the abandonment of what is stated [in śruti] is also purposeless.
