The Kāśikāvṛtti, the oldest available complete commentary on Pāṇini’s grammar, the Aṣṭādhyāyī, is found quoted often in the later Pāṇinian grammatical tradition. These quotations throw light on a number of aspects of the text of the Kāśikāvṛtti. This paper focuses on how this later Pāṇinian grammatical tradition views the modifications in the text of the Aṣṭādhyāyī (generally ascribed to the text of Kāśikāvṛtti by modern scholarship) and concludes that also the tradition ascribes these modifications to the Kāśikāvṛtti. Further, this paper also attempts to show that these quotations can be shown to have interacted with the manuscript tradition of the Kāśikāvṛtti and indeed with the help of these quotations it becomes easier to better understand the manuscript transmission of the Kāśikāvṛtti. Thus, this article focuses on one of the applications of the study of quotations: through an analysis of the content of the quoted passages of the Kāśikāvṛtti (hereafter KV) in later Grammatical literature, it discusses the history of the transmission of the KV and of the text it comments upon, i.e., Pāṇini’s Aṣṭādhyāyī. It also shows how a study of quotations is an unavoidable complement of the analysis of manuscripts for scholars aiming at the reconstruction of texts so remote in time.
