Original

ज्ञापनीयमवेदत्वं यद्वा युक्त्या ध्रुवं त्वया ।
अन्यथाश्रुत्यनुक्तत्वं संदिग्धं तस्य ते भवेत् ॥ ३५२१ ॥

jñāpanīyamavedatvaṃ yadvā yuktyā dhruvaṃ tvayā |
anyathāśrutyanuktatvaṃ saṃdigdhaṃ tasya te bhavet || 3521 ||

It behoves you to prove beyond doubt that the text in question is not ‘Veda’; as otherwise, the reason that you have put forward (against the omniscient person) that he is not mentioned in the ‘Veda’ becomes doubtful.—(3521)

Kamalaśīla

‘Otherwise’—i.e. if you do not establish the fact that it is not Veda; in that case, what you have asserted regarding the Omniscient Person being not mentioned in the ‘Veda’, becomes open to doubt and hence ‘Inadmissible’ (as Reason).—(3521)
