accompanied by the antecedent non-existence of consciousness. Nor do we meet with any scriptural text referring to this antecedent non-existence. Hence, in the absence of any valid instrument of knowledge, the antecedent non-existence of consciousness cannot be established at all.--If, we reply, you thus, altogether setting aside the force of self-provedness (on which you had relied hitherto), take your stand on the absence of valid means of knowledge, we again must request you to give in; for there is a valid means of knowledge whereby to prove the antecedent non-existence of consciousness, viz. valid non-perception (anupalabdhi). Moreover, we observe that perceptional knowledge proves its object, be it a jar or something else, to exist only as long as it exists itself, not at all times; we do not, through it, apprehend the antecedent or subsequent existence of the jar. Now this absence of apprehension is due to the fact that consciousness itself is limited in time. If that consciousness which has a jar for its object were itself apprehended as non-limited in time, the object also--the jar--would be apprehended under the same form, i.e. it would be eternal. And if self-established consciousness were eternal, it would be immediately cognised as eternal; but this is not the case. Analogously, if inferential consciousness and other forms of consciousness were apprehended as non-limited in time, they would all of them reveal their objects also as non-limited, and these objects would thus be eternal; for the objects are conform in nature to their respective forms of consciousness. There is no consciousness without object. Nor is there any consciousness devoid of objects; for nothing of this kind is ever known. Moreover, the self-luminousness of consciousness has, by our opponent himself, been proved on the ground that its essential nature consists in illumining (revealing) objects; the self-luminousness of consciousness not admitting of proof apart from its essential nature which consists in the lighting up of objects. And as moreover, according to our opponent, consciousness cannot be the object of another consciousness, it would follow that (having neither an object nor itself being an object) it is something altogether unreal, imaginary.
