Traditionally, spirituality refers 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. In modern times the emphasis is on subjective experience of a sacred dimension and the "deepest values and meanings by which people live," often in a context separate from organized religious institutions. Modern systems of spirituality may includes a belief in a supernatural (beyond the known and observable) realm, personal growth, a quest for an ultimate or sacred meaning, religious experience, or an encounter with one's own "inner dimension."
The meaning of spirituality has developed and expanded over time, and various connotations can be found alongside each other.[note 1] The term "spirituality" originally developed within early Christianity, referring to a life oriented toward the Holy Spirit. During late medieval times the meaning broadened to include mental aspects of life, while in modern times the term both spread to other religious traditions and broadened to refer to a wider range of experience, including a range of esoteric traditions.
