From Commentary to paribhāṣās: Kātyāyana and Patañjali vis-à-vis Vyāḍi

The present paper is targeted on three landmarks in the long story of the paribhāṣās’ development. Two of these landmarks descended from the earliest testimony of Vyākaraṇa meta-rules, i. e. those included in Pāṇini’s grammar (fifth–fourth century BCE), and one which has been handed down as the first independent collection of paribhāṣās and attributed to Vyāḍi. In particular a shift is highlighted between Kātyāyaṇa’s (third century BCE) integrative approach (vacana) and Patañjali’s (second century BCE) recourse to implicit paribhāṣās in the Aṣṭādhyāyī as a powerful hermeneutical tool. A shift that helps in interpreting the need for a validation and collection of implicit pāṇinian paribhāṣās as carried out by authors such as Vyāḍi.
