The Article is concerned with the investigation of interpretation of the concept "pratyakṣa" in the first chapter of the first part of "Nyāya Sūtras", which became the determining ground for the entire subsequent history of the development of this concept in the teachings of the adherents of this philosophical school and their polemics with opponents. The methods of etymological and contextual analysis are applied, the key meaningful connotations of "pratyakṣa" are outlined, and the main issues of its interpretation and translation (...) are revealed. The first chapter of the first part of "Nyāya Sūtras" is the systemic core of the work as a whole, therefore its thorough study is of primary importance, both for the reconstruction of the teachings of Nyāya darshan, and for clarifying the specifics of the actualization of the lexemes presented in this part of the text and in the philosophical discourse of India as a whole. However, the brevity of the text chosen for analysis in this article opens a rather comprehensive perspective of different interpretations and creates a number of open questions. The duration of the tradition of comments dedicated to "Nyāya Sūtras" is an evidence of the importance of this work and the difficulty of reconstructing its content. The open questions actualized in the process of this study should not only become the basis for further investigations, but also reveal the specifics of the problematization of "pratyakṣa" in the philosophical discourse of India. The article reveals that the study of the concept of "pratyakṣa" in the teaching of Nyaya darshan, first of all, requires the analysis of the following concepts: prama̅ṇa, indriya, manas, artha, jñāna, buddhi. The article also suggests that "pramana pratyakṣa" is rather a "situation" of acquiring knowledge that meets the criteria of truth, rather than a simple "tool of knowledge" or "ability to know", so its simple translation as "perception" seems insufficiently substantiated. The article declares that the issue whether every contact between indriya and artha necessarily leads to the formation of a jñāna that meets the criteria of avyapadeśyam ("that which precedes definition and expression"), avyatirekavyabhicārin ("that which is clear, distinct, uncontroversial and steady'), vyavasāyātmaka ('that which is intense, bright and full of energy') is open and urgent for further research. It also states that the issues whether it is possible to talk about the contact of indriya, in the sense of a simple list of empirical senses (sight, hearing, touch, taste, smell), with artha without the mediation of manas; and how to interpret the possible role of the Western concept of "consciousness" in this process are also important.
