It is well known that there are differences in the definition of trairūpya theory between Dignāga and Dharmakīrti, especially in the third characteristic. Jinendrabuddhi, a commentator on the Pramāṇasamuccaya (PS) and Pramāṇasamuccayavṛtti (PSV), interprets the two texts while adopting Dharmakīrti’s definition in such a way that even Dignāga’s statement does not cause problems.
Jinendrabuddhi, in his Pramāṇasamuccayaṭīkā, explains the word nāstitā as nāstitā-eva and asati as <abhāva>, <anya> and <viruddha> in the phrase nāstitāsati of PS 2.5cd. Thereby, his understanding of PS comes close to Dharmakīrti’s theory of the third characteristic. This assertion that nāstitā of PS has a restriction indicated by eva also applies to nāstitā in the phrase asaty eva nāstitā of PSV. In addition to this, he states that anya in the phrase nānyatra of PSV means “what is different from asat,” not “what is different from sapakṣa.” Furthermore, na viruddha iti indicates that asat is incompatible with nāstitā. Such an interpretation of PSV by Jinendrabuddhi is aimed at refuting Uddyotakara, who criticizes Dignāga’s definition of the third characteristic.
Although Jinendrabuddhi’s interpretation of Dignāga’s PS and PSV does not correspond to Dignāga’s intention, it is meaningful in that he tries to bridge the gap between Dignāga and Dharmakīrti and defends Dignāga against criticisms of Uddyotakara.
