Tattvavivekaḥ – An Overview
Tattvavivekaḥ is a concise examination of the structure of reality and the distinctions through which it may be correctly understood. In thirteen verses, Madhvācārya begins from the fundamental division between the independent and the dependent. Viṣṇu alone is independent, free from all defects and possessed of all auspicious qualities; everything else belongs to dependent reality.
Dependent reality is divided into existence and absence, while existent reality is further classified as sentient and insentient. Among sentient beings, Madhva distinguishes the eternally liberated Śrī from other jīvas, and describes gradations among liberated and unliberated beings. The latter are divided according to their destinies: those eligible for liberation, those who remain in transmigration, and those destined for eternal darkness. Thus difference and hierarchy are presented as intrinsic features of the order of reality.
The work then turns to insentient existence. Space, time, revelation, elements, senses, vital forces, qualities, and their transformations are considered in relation to eternality and change. Madhva distinguishes an entity from its modifications without reducing either to unreality. Qualities, actions, universals, and other attributes belong genuinely to things.
The most distinctive portion of Tattvavivekaḥ examines the relation between unity and difference. Madhva considers such pairs as substance and modification, cause and effect, quality and its possessor, action and agent, universal and particular, the qualified entity and its underlying reality, and part and whole. These distinctions allow plurality and change to be affirmed without denying the continuity of the underlying entity.
The treatise concludes by giving this analysis a spiritual purpose. To understand that the entire dependent order, in all its diversity, remains always under Hari’s control is not merely metaphysical knowledge; Madhva declares such understanding to be a means to freedom from saṃsāra. Tattvavivekaḥ therefore joins careful discernment of reality with the ultimate purpose of philosophical knowledge.
