एकान्तिकमसंबन्धाद्गम्यतेऽन्यनिवर्त्तनम् ॥ १२१ ॥yaśca naivaṃvidho bhāvastasya naiva nivṛttitaḥ |
ekāntikamasaṃbandhādgamyate’nyanivarttanam || 121 ||When a thing is neither the one nor the other, its absence does not conclusively preclude the other thing; because there is no connection.—(121)
Kamalaśīla
It might be argued that—“Even though not invariably concomitant, the Proof (being absent) may yet preclude the existence of the Thing—The answer to this is provided by the following Text:—[see verse 121 above]
Neither the one nor the other,—i.e. neither the Cause, nor pervasive;—the absence of what is not invariably concomitant cannot rightly be taken as necessarily precluding the other thing; for if it did, it would lead to an absurdity: the absence of the Horse might, in that case, imply the absence of the Cow also.—(121)
