हेत्वर्थः करणार्थश्च पूर्ववत्तेन वात्मना ।
यदि वस्तु विजातीयान्न स्याद्भिन्नं न तत्तथा ॥ १०७४ ॥hetvarthaḥ karaṇārthaśca pūrvavattena vātmanā |
yadi vastu vijātīyānna syādbhinnaṃ na tattathā || 1074 ||As before, the instrumental ending may signify either the cause or the instrument. or it may signify that it is ‘in that form’.—If the thing were not differentiated from unlike things, then it could not be so.—(1074)
Kamalaśīla
In the following Text the author applies the Instrumental ending in the compound ‘arthāntaraparāvṛttyā’ in the case in question:—[see verse 1074 above]
‘As before’;—i.e. just as under Texts 1068-1070,—where it is said that ‘the Word expresses things as qualified by the exclusion of other things’,—so the same may be applied here also.—Or in all cases, the Instrumental Ending may be taken as signifying the idea of being ‘in that form’;—tills is what is mentioned by the words ‘tena vātmanā’.
Question:—“The exclusion of other things is a property belonging to the Object; as such, how can it be either the Cause or the Instrument of the apprehension of the Reflection?”
Answer:—‘If the thing, etc. etc.’—That is, if the Thing were not excluded (and differentiated) from unlike things, then, in the form of its Reflection, it could not be apprehended as something excluded from unlikengs. That is why the exclusion from other things is to be regarded as the Cause and the Instrument.—(1074)
