This article presents a research perspective that aims to explore religion as a basis for the construction of psychological knowledge. It is assumed that religious doctrine and practice have access to contents that pertain to local forms of human mental life. Taking into account the presuppositions of indigenous psychology has resulted in a proposal to extend scope of current academic psychology and combine knowledge provided by national/ethnic psychologies that are not identical to Occidental psychology. We propose ways of using the religious conception of soul and of religious rites of passage that correspond with real psychology and subjective understanding of humanity to reconstruct a local perception of human development. The pre-Christian religion of the Slavs will be used as an example.
