প্রস্থানভেদঃ (Prasthānaveda)

The present work is a commentary by Madhusudana Saraswati on a part of Śivamahimāstotra (Hymns to the glory of Śiva) written by Puṣpadanta. In this commentary, Madhusudana talks about eighteen disciplines of knowledge. All the āstika and nāstika systems of knowledge could be included in the eighteen disciplines and all these systems of knowledge, either directly or indirectly, aimed at determining the nature of god. According to Madhusudana, even the philosophy of art written by Bharata aims at worshiping god. Madhusudana argues that one could talk about three fundamental prasthānas viz. ārambhavāda, parināmavāda and vivartavāda. We start our intellectual journey from ārambhavāda and then through pariṇāmavāda reach vivartavāda. It is only in vivartavāda that one realizes that the world is a vivarta of Brahmaṇ. The varieties of prasthānas have been created only to cater to the needs of people of various inclinations.

जागदीशीव्याधिकरणम् (Jāgadīśvyādhikaraṇam)

This is a prakaraṇa text on the Nyāya theory of vyāpti written by Jagadīśa. The main theme of the work centres around the nature of vyāpti.Knowledge of vyāpti is the cause of inferential knowledge. If the definition of vyāpti is constructed in terms of avyābhicāritatva, then one could explain  avyābhicāritatva in five alternative ways. And none of these alternatives is acceptable, for this understanding of vyāpti would fail to account for kevalānvayi inference. In order to remove this problem, the definition of vyāpti is reconstructed as pratiyogivṛttidharmāvacchinna-pratiyogitākabhāvarupa vyādhikaraṇadharmāvacchinnabhāva. Jagadīśa examines this new definition of vyāpti and offers his justification, refuting all the possible objections.

सिद्धान्तलक्षणम् (Siddhānta Lakṣaṇam)

The final definition of vyāpti, known as siddhāntalakṣaṇa, has been explained by Jagadīśa in this work. The final definition of vyāpti is: where pratiyogyasāmānadhikaraṇya tāsāmānādhikaraṇatyantābhāvāpratiyogitāvacchedakabhacchinam does not hold, their vyāpti stays in the same locus. Raghunātha Śiromaṇi comments on this definition of vyāpti. Jagadīṣa further explains this final definition of vyāpti.

Gādādhari Volume-2

In these two volumes, Gadādhara Bhhattācārya offers a detailed analysis of the views found in Tattvacintāmaṇi of Gaṅgeśa and in Dīdhiti of Raghunātha Śiromaṇi. Almost all the major conclusions of Navya-Nyāya have been explained with great defence.

मुक्तिबादबिचारः (Muktivādavicaraḥ)

This book is an essay on Nyāya theory of liberation. Harirāma Tarkavāgīśa, in this book, critically assesses the generally accepted definition of liberation as permanent (ātyantika) cessation (nivṛtti) of suffering (duhkha). The debate revolves around explaining the terms like ‘atyanta’ and ‘nivṛtti’. Harirama argues that the widely accepted understanding of these words fails to cover all the different kinds of liberation that philosophers talk about. Harirama proposes to describe liberation as the destruction of final suffering and the idea of finality could be understood as a universal inhering in suffering. Harirama argues that if knowledge of reality is to be regarded as the cause of liberation, then liberation is to be regarded as the permanent post-negation of sin and not of misery.
