The paper discusses the desecularization of public consciousness in modern Buryatia in the overall context of a religious revival in Russia. Basing on the functional approach, the author discusses the most important characteristics of religiosity among Buryats including the measurement of ethnocultural identity. Simultaneously, the author undertakes an analysis of the correlation between, on the one hand, revival of worldview foundations of religion and, on the other hand, banal religiosity as constructing ethnic differentiation.
