Abstract: The article is devoted to the philosophical views of Swami Vivekananda, reflected in his commentary on the Yoga Sutras of Patanjali. The text under study is one of the few Indian commentaries on the Yoga Sutras translated into Russian. The object of the study is a widespread translation of the commentary, made and published by Ya. K. Popov in 1906. The popularity of yoga as a health-improving practice increases interest in its spiritual component, therefore, the study of Vivekananda's commentary on the Yoga Sutras seems to be an urgent task. The purpose of this article is to analyze Vivekananda's commentary for the authenticity of the transmission of the content of the ancient text and the reflection of the teachings of the Bengali thinker. Since Vivekananda's commentary on the Yoga Sutras has not been studied by domestic orientalists, and has not received comprehensive coverage in foreign studies, the results of his analysis contain scientific novelty. Using the hermeneutical method, it is revealed that the philosopher forms a commentary on the ancient text mainly to demonstrate the basics of his teaching. Vivekananda's work expresses his Orient-centric position, as well as the author's beliefs in accordance with the provisions of yoga to his contemporary science. Since the philosopher's views are in line with Advaita Vedanta, the ontological foundations of yoga are interpreted by him according to this philosophical school. The commentary of the late XIX century anticipates modern ideas of the healing potential of yoga and the superiority of experienced knowledge of the Divine, and also demonstrates the predictive talent of the Bengali thinker.
