因明入正理論疏 3.188

3.188

言「相有三」，釋前眾相，離重言失，故指如前。由「彼為因」，釋前藉義。「由」即因由，藉待之義。「於所比義」，此即釋前而觀於義。前談照境之能，曰之為觀。後約籌慮之用，號之曰比。言於所彰結比故也。

The words 'the characteristics are of three kinds' explain the earlier 'multiple characteristics.' To avoid the fault of repetition, it refers to them 'as previously explained.' 'Taking them as the reason' explains the earlier meaning of 'relying.' 'Taking' means relying on and depending upon. 'With respect to the object to be inferred' explains the earlier 'observing an object.' The earlier [passage] discussed the capacity to illuminate the object and called it 'observing.' The later [passage] concerns the function of deliberation and designates it 'inference.' The word 'with respect to' is used to conclude the inferred.
