The Essence of Absence: Understanding Abhāva in Indian Philosophy By Gobinda Barman Student, University of Hyderabad Abstract: Abhāva (absence) is an important aspect in Indian philosophy, this paper mainly focuses on the idea of Abhāva particularly within the framework of Nyaya-Vaisheshika tradition. The Nyaya-Vaisheshika philosophers divide Padartha (category) into two main categories: Bhāva (existence) and Abhāva (non-existence). Bhāva Padārtha are considered as absolute but Abhāva is relative in its conception. The discussion explores various perspectives on the recognition of Abhāva as a distinct category. This paper focuses on the debate surrounding the recognition of Abhāva as a Padartha is thoroughly analysed in this paper.. Also, the paper investigates the relationship between absence and its locus, focusing on the need to consider Abhāva as a distinct category beyond its locus. The significance of the Ādhāra-ādhēẏa relationship between absence and its locus is highlighted. In conclusion, I try to establish that recognizing Abhāva as a distinct category is important because it is not merely the negation of existence but constitutes a unique category with its own characteristics. ___________________________________________________________________________ In Nyaya-Vaisheshika philosophy, abhāva padārtha refers to the non-existence of something. For example, while our subject of knowledge may be the existence of a table, it also includes the absence of a vase on that table. The Nyaya-Vaisheshika philosophical tradition, known for its materialist worldview, holds that any object of knowledge entails an additional category beyond the knowledge itself. Thus, the absence of a vase is not simply a cognitive reality, but also an essential part of our thinking. In his work Vaishesika Sutra, Maharishi Kanada describes six Bhāva Padārthas (categories) without specifically recognising Abhāva as a distinct category. However, he acknowledges the concept of Abhāva. Notably, even Prasadpada's commentary on the text does not identify Abhāva as a distinct substance. Subsequent commentators recognised seven categories, including Abhāva in the framework. When we talk about a word, it naturally refers to something real. For example, when an arrow is shot, it must hit an existing object in the external world. The presence of absence can be known from its consequences. For example, when we are hungry, we detect a lack of food in our stomach. Similarly, when we miss a loved one, we feel the lack of their presence. When we look at a bald man, we notice the lack of hair on his head. We also notice the absence of money in our pockets, especially near the end of the month, or the absence of colour in a piece of cloth, or even the absence of tolerance in various situations. Barman 1
