सद्ग्राहकप्रमाभावान्न वा सत्ता प्रसिध्यति ।
प्रमाणविनिवृत्तौ हि नार्थाभावेऽस्ति निश्चयः ॥ ५५५ ॥sadgrāhakapramābhāvānna vā sattā prasidhyati |
pramāṇavinivṛttau hi nārthābhāve’sti niścayaḥ || 555 ||It may be that the existence of a thing cannot be known in the absence of a means of the right cognition of the existing thing. But the mere absence of the means of right cognition cannot bring about certainty regarding its being actually nonexistent.—(555)
Kamalaśīla
‘Cannot bring about certainty, etc.’,—as is found in the case of such things as the Ghost (which is not seen, and yet one cannot be sure that it does not exist).—(555)
