Introduction. The purpose of the article is to consider the specifics of the approach to religious and mystical experience in the psychoanalytic tradition from the point of view of revealing the degree of its interdisciplinarity. Theoretical analysis. Using the methods of critical philosophical reflection and dialectical logic, as well as relying on the principle of development, the authors analyze the emergence of the figure of a “psychoanalytic mystic”, going in the direction of overcoming the antithesis of the scientific nature of psychoanalytic theory and the non-scientific nature of religious and mystical phenomena. At the same time, special attention is focused on the factors of interdisciplinary interaction that contributed to the meaningful renewal of psychoanalysis. Conclusion. The logic of the study led to the conclusion that interdisciplinarity manifested itself not simply in borrowing, but in the germination of religious and mystical, and along with them, esoteric elements of spiritual practice within the framework of theory and practice of psychoanalysis.
