(_b._) Nor can the non-existent be produced from the existent; since it is impossible that that which, previous to the operation of the originating cause, was as non-existent as a hare's horn should ever be produced, _i.e._, become connected with existence; for not even the cleverest man living can make blue yellow.[356] If you say, "But are not existence and non-existence attributes of the same jar?" this is incorrect, since we cannot use such an expression as "its quality" in regard to a non-existent subject, for it would certainly imply that the subject itself did exist. Hence we conclude that the effect is existent even previously to the operation of the cause, which only produces the manifestation of this already existent thing, just like the manifestation of the oil in sesame seed by pressing, or of the milk in cows by milking. Again, there is no example whatever to prove the production of a thing previously non-existent. Moreover, the cause must produce its effect as being either connected with it or not connected; in the former alternative the effect's existence is settled by the rule that connection can only be between two existent things; in the latter, any and every effect might arise from any and every cause, as there is nothing to determine the action of an unconnected thing. This has been thus put by the Sáṅkhya teacher:--"From the supposed non-existence of the effect, it can have no connection with causes which always accompany existence; and to him who holds the production of a non-connected thing there arises an utter want of determinateness." If you rejoin that "the cause, though not connected with its effect, can yet produce it, where it has a capacity of so doing, and this capacity of producing is to be inferred from seeing the effect actually produced," still this cannot be allowed, since in such a case as "there is a capacity for producing oil in sesame seeds," you cannot determine, while the oil is non-existent, that there is this capacity in the sesame seeds, whichever alternative you may accept as to their being connected or not with the oil [since our before-mentioned dilemma will equally apply here].
