 According to Śrīharṣa, this definition doesn’t work because it suffers from the problem of irrelevance (even though the problem also seems to arise for the previous proposal). It would predict that even intuitively causally irrelevant factors which are necessarily present before the production of an effect are causally relevant to the production of that effect. For instance, it predicts that just as the threads that constitute a cloth are causally relevant to the production of the cloth, so also is the color of those threads causally relevant to the production of the cloth, when it intuitively isn’t.
