The paper presents the results of theoretical analysis and empirical study of non-spiritual life meanings that lead to life meaning crises in the course of personality development. Non-spiritual life meaning is seen as a functionally suboptimal meaning that is based mainly on egocentric values with no or minimal presence of self-transcendent values. The results of the empirical study suggest that adoption of such a pattern of values as sources of life meaning by a personality leads to a more intense experience of life meaning crisis.
