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 " 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.
In modern times, the term both spread to other religious traditions and broadened to refer to a wider range of experiences, including a range of esoteric and religious traditions. Modern usages tend to refer to a 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. This may involve belief in a supernatural realm beyond the ordinarily observable world, personal growth, a quest for an ultimate or sacred meaning, religious experience, or an encounter with one's own "inner dimension". Rabbi Dr. Eric Lankin has noted “Spirituality is a personal quest for the transcendent, how one discerns life’s meaning in relation to God and other human beings. Healthy spirituality fosters healthy relationships and affirms all of life’s experiences as part of
the journey.”
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, ghost, 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 ruach.
The term "spiritual", meaning "concerning the spirit", is derived from Old French spirituel (12c.), which is derived from Latin spiritualis, which comes by 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.
