Spiritual transformation is a fundamental change in a person's sacred or spiritual life.
In psychology, spiritual transformation is understood within the context of an individual's meaning system, especially in relation to concepts of the sacred or ultimate concern. Two of the fuller treatments of the concept in psychology come from Kenneth Pargament and from Raymond Paloutzian. Pargament says that "at its heart, spiritual transformation refers to a fundamental change in the place of the sacred or the character of the sacred in the life of the individual. Spiritual transformation can be understood in terms of new configurations of strivings" (p. 18). Paloutzian says that "spiritual transformation constitutes a change in the meaning system that a person holds as a basis for self-definition, the interpretation of life, and overarching purposes and ultimate concerns" (p. 334).
The Metanexus Institute in New York has sponsored scientific research on spiritual transformation.
