因明入正理論疏 2.57

2.57

述曰：若為二科，下隨今列，初三闕依、後一義順。若為三科，下顯非有，宗非兩許，依必共成。依若不成，宗依何立？且如四支無闕，勝軍可成；眾支既虧，勝軍寧立？故依非有，宗義不成。

The commentary says: If divided into two rubrics, below follows the modern listing: the first three lack a substratum (āśraya), and the latter one conforms in meaning. If divided into three rubrics, below shows unreality: the thesis is not mutually accepted, whereas the substratum must be mutually established. If the substratum is not established, upon what can the thesis be based? For example, if the four divisions [of an army] are not lacking, a victorious army can be accomplished; but once multiple divisions are deficient, how could a victorious army stand? Therefore, if the substratum does not exist, the meaning of the thesis cannot be established.
