अनुमेयेऽथ तत्तुल्ये सद्भावो नास्तिता सति' is a half Couplet in the Pramānasamuccaya' meant to explain the nature of the 'त्रैरूप्य ' of the ‘linga' or ' hetu' involved in Dinnāga's definition of the Inference for one's self as 'त्रिरूपालिङ्गतोऽर्थदृक् ' ' stated by him in the first Kärikā of the second chapter of his work.
