「又所現像至為勝依性」者，此約二生破。像由二緣，勝者即現。生有唯一，死有為緣，無別勝依，故喻非等法。亦不可說精血等緣為勝依性。胎生可爾，化復如何？

"Furthermore, as for 'the reflected image that appears [...] serving as the superior support'" refutes it in terms of two origins. An image depends on two conditions: when the superior one is present, it appears. Existence at conception (upapatti-bhava) has only one [condition]: it takes existence at death (maraṇa-bhava) as its condition and has no separate, superior support. Therefore, the metaphor is not equivalent to the phenomenon. Nor can one say that conditions such as semen and blood serve as the superior support. This might be so for the womb-born, but what of the apparitionally born?
