The meaning of spirituality has developed and expanded over time, and various meanings can be found alongside each other. Traditionally, spirituality referred to a religious process of re-formation which "aims to recover the original shape of man", oriented at "the image of God" as exemplified by the founders and sacred texts of the religions of the world. The term was used within early Christianity to refer to a life oriented toward the Holy Spirit and broadened during the Late Middle Ages to include mental aspects of life.

Definition There is no single, widely agreed-upon definition of spirituality. Surveys of the definition of the term, as used in scholarly research, show a broad range of definitions with limited overlap. A survey of reviews by McCarroll, each dealing with the topic of spirituality, gave twenty-seven explicit definitions among which "there was little agreement". This causes some difficulty in trying to study spirituality systematically; i.e., it impedes both understanding and the capacity to communicate findings in a meaningful fashion. According to Kees Waaijman, the traditional meaning of spirituality is a process of re-formation that "aims to recover the original shape of man, the image of God. To accomplish this, the re-formation is oriented at a mold, which represents
