शब्दशक्तिप्रकाशिका (Śabdaśaktiprakāśikā (Vol-3))

The third volume of Śabdaśaktiprakāśikā contains an analysis of samāsa. The book starts with a presentation and analysis of the definition of samāsa in general. Jagadīśa distinguishes nitya samāsa from anitya samāsa. The present work contains an analysis of six kinds of samāsa, viz, 1. Dvigu, 2. Tatpuruṣa, 3. Avyaībhāva, 4. Bahubrīhi, 5. Dvandva. The author accepts another samāsa viz. Upapada. The Grammarians hold that the vigraha vākya and the samasta vākya do not have the same śakti and so the nature of understanding the meaning of the vigraha vākya does not amount to understanding the meaning of the samāsa. Jagadīśa refutes this view of the Grammarian and argues that both the vigraha vākya and the samāsa do possess the same meaning. While the traditional Pāṇinian grammar includes karmadhārāya samāsa in tatpuruṣa samāsa and dvigu samāsa in karmadhāraya samāsa, the Katantra Grammar includes dvigu samāsa in tatpuruṣa samāsa. Jagadīśa intervenes in this debate and holds that karmadhāraya and dvigu are independent samāsas and so he thinks that there are six kinds of samāsas viz. tatpuruṣa, avyaībhāva, bahubrīhi, dvandva, karmadhārāya and dvigu. In this book one finds a detailed analysis of all these six kinds of samāsa. Even if Jagadīśa does not accept upapada samāsa as an independent samāsa, still he offers an analysis of upapada samāsa on behalf of those who accept upapada samāsa.

शक्तिबाद (Śaktivādaḥ)

In this book, Gadādhara Bhattāchārya presents a theory of the meaning of words. This work is divided into three chapters: 1. Sāmānyakāṇḍa, 2. Viśesakāṣḍa and 3. Pariśiṣtakāṇḍa. In Sāmānyakaṇḍa, the author undertakes a detailed analysis of vṛtti of words. Here one comes across a definition of śakti in terms of which a word denotes its meaning. The theory of anvitābhidhāna has been refuted. In the Viśeṣakaṇḍa, the author undertakes an analysis of the meaning of words denoting an individual and the meaning of the words denoting a universal. Prabhākara theory of meaning has been refuted. This chapter contains an analysis of indexicals and demonstratives. The third chapter viz. Pariśiṣtakaṇḍa contains a defence of the view that the śakti of a word lies in the individual that is qualified by the corresponding universal. Views of several Mīmāṃsaka philosophers have been critically assessed.
