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 spirituality typically includes a belief in a supernatural (beyond the known and observable) realm,personal growth, a quest for an ultimate/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. 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.
The term spirit means "animating or vital principle in man and animals". It is derived from the Old French espirit which comes from the Latin word spiritus (soul, courage, vigor, breath) and is related to spirare (to breathe). In the Vulgate the Latin word spiritus is used to translate the Greek pneuma and Hebrew ruah.
The term "spiritual", matters "concerning the spirit", is derived from Old French spirituel (12c.), which is derived from Latin spiritualis, which comes from spiritus or "spirit".
The term "spirituality" is derived from Middle French spiritualité, from Late Latin "spiritualitatem" (nominative spiritualitas), which is also derived from Latin spiritualis.
There is no single, widely agreed definition of spirituality. Surveys of the definition of the term, as used in scholarly research, show a broad range of definitions ranging from very narrow and uni-dimensional definitions such as a personal belief in a supernatural realm to broader concepts such as a quest for an ultimate/sacred meaning, transcending the base/material aspects of life, and/or a sense of awe/wonderment and reverence toward the universe. A survey of reviews by McCarroll e.a. 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. Indeed, many of spirituality's core features are not unique to spirituality alone; for example German philosopher Arthur Schopenhauer (a famous atheist) regarded self-transcendence, asceticism and the recognition of one's connection to all as a key to ethical living (see)
