As such, the spiritual is traditionally contrasted with the material, the temporal and the worldly. A perceived sense of connection forms a central defining characteristic of spirituality — connection to a metaphysical reality greater than oneself, which may include an emotional experience of religious awe and reverence, or such states as satori or nirvana. Equally importantly, spirituality relates to matters of sanity and of psychological health. Spirituality is the personal, subjective dimension of religion, particularly that which pertains to liberation or salvation (see also mysticism and esoterism) .
Spirituality as a way of life concerns itself with aligning the human will and mind with that dimension of life and the universe that is harmonious and ordered. As such spiritual disciplines (which are often part of an established religious tradition) enjoin practitioners (trainees or disciples) to cultivate those higher potentialities of the human being that are more noble and refined (wisdom and virtue). Accordingly, many spiritual traditions across diverse cultures share similar vocabulary. Terms such as the "path", the "work", the "practice" are universally applied to the ongoing discipline involved in transforming the coarser energies present in the human soul into more subtle and pleasing ones. As a spiritual practitioner one seeks to become free of the lesser egoic self (or ego) in favor of being more fully one's "true" "Self".
An important distinction exists between spirituality in religion and spirituality as opposed to religion.
In recent years, spirituality in religion often carries connotations of a believer having a faith more personal, less dogmatic, more open to new ideas and myriad influences, and more pluralistic than the doctrinal/dogmatic faiths of mature religions. It also can connote the nature of believers' personal relationship or "connection" with their god(s) or belief-system(s), as opposed to the general relationship with a Deity as shared by all members of a given faith.
Those who speak of spirituality as opposed to religion generally meta-religiously believe in the existence of many "spiritual paths" and deny any objective truth about the best path to follow. Rather, adherents of this definition of the term emphasize the importance of finding one's own path to whatever-god-there-is, rather than following what others say works. In summary: the path which makes the most coherent sense becomes the correct one (for oneself).
Many adherents of orthodox religions who regard spirituality as an aspect of their religious experience tend to contrast spirituality with secular "worldliness" rather than with the ritual expression of their religion.
People of a more New-Age disposition tend to regard spirituality not as religion per se, but as the active and vital connection to a force/power/energy, spirit, or sense of the deep self. As cultural historian and yogi William Irwin Thompson (1938 - ) put it, "Religion is not identical with spirituality; rather religion is the form spirituality takes in civilization." (1981, 103)
For a religious parallel to the approach whereby some see spirituality in everything, compare pantheism.
To Christians, sometimes refer to themselves self as "more spiritual than religious" implies relative deprecation of rules, rituals, and tradition while preferring an intimate relationship with God and/or talking to Him as one's best friend. Their basis for this belief is that Jesus Christ came to free man from those rules, rituals, and traditions, giving them the ability to "walk in the spirit" thus maintaining a "Christian" lifestyle through that one-to-one relationship with God. Some excellent resources that further explain the "spiritual Christian" are found in the Bible, Gospel of John 4:24 for example, and in the works of Watchman Nee. Nee probes deeply into the building blocks of mankind and derives that we are Spirit, Body and Soul.
"Being spiritual" may aim toward:
Plato's allegory of the cave in book VII of The Republic gives a well known description of the spiritual development process, and may provide an aid in understanding what "spiritual development" exactly entails.
Spirituality has played a central role in self-help movements such as Alcoholics Anonymous: "...if an alcoholic failed to perfect and enlarge his spiritual life through work and self-sacrifice for others, he could not survive the certain trials and low spots ahead....
Analysis of spiritual qualities in science faces problems — such as the imprecision of spiritual concepts, the subjectivity of spiritual experience, and the amount of work required to translate and map observable components of a spiritual system into empirical evidence.
Science takes as its basis empirical, repeatable observations of the natural world, and thus generally regards ideas that rely on supernatural forces for an explanation as beyond the purview of science. Scientists regard ideas which present themselves as scientific, but which rely on a supernatural force for an explanation, as religious rather than scientific; and may label such idea as pseudo-science. In this context scientists may oppose spirituality, at least in the scientific sphere.
New Age physicist-philosopher Fritjof Capra has articulated connections between what he sees as the spiritual consequences of quantum physics. Ken Wilber, in an attempt to unite science and spirituality, has proposed an "Integral Theory of Consciousness".
Ervin László posits a field of information as the substance of the cosmos. Using the Sanskrit and Vedic term for "space", akasha, he calls this information-field the "Akashic field" or "A-field". He posits the "quantum vacuum" (see Vacuum state) as the fundamental energy- and information-carrying field that informs not just the current universe, but all universes past and present (collectively, the "Metaverse").
Eighteenth-century Enlightenment thinkers, often opposed to clericalism and skeptical of religion, sometimes came to express their more emotional responses to the world under the rubric of "the Sublime" rather than discussing "spirituality". The spread of the ideas of modernity began to diminish the role of religion in society and in popular thought.
Schmidt sees Ralph Waldo Emerson (1803–1882) as a pioneer of the idea of spirituality as a distinct field. Phineas Quimby (1802-1866) and New Thought played a role in emphasizing the spiritual in new ways within Christian church traditions during the 19th century.
In the wake of the Nietzschean concept of the "death of God" in 1882, people unpersuaded by scientific rationalism turned increasingly to the idea of spirituality as an alternative both to materialism and to traditional religious dogma.
Important early 20th century writers who studied the phenomenon of spirituality include William James (The Varieties of Religious Experience (1902)) and Rudolph Otto (especially The Idea of the Holy (1917)).
The distinction between the spiritual and the religious became more common in the popular mind during the late 20th century with the rise of secularism and the advent of the New Age movement. Authors such as Chris Griscom and Shirley MacLaine explored it in numerous ways in their books. Paul Heelas noted the development within New Age circles of what he called "seminar spirituality": structured offerings complementing consumer choice with spiritual options.
In English the word "spirit" comes from the Latin spiritus, meaning "breath" (compare spiritus asper), but also "soul, courage, vigor", ultimately from a PIE root *(s)peis- (to blow). In the Vulgate, the Latin word translates Greek (πνευμα), pneuma (Hebrew (רוח) ruah), as opposed to anima, translating psykhē. The word was loaned into Middle English via Old French.
Many spiritual traditions promote courses of study in spirituality.
Building on both the Western esoteric tradition and theosophy, Rudolf Steiner and others in the anthroposophic tradition have attempted to apply systematic methodology to the study of spiritual phenomena. This enterprise does not attempt to redefine natural science, but to explore inner experience — especially our thinking — with the same rigor that we apply to outer (sensory) experience.
Overall, scholars in disciplines such as theology, religious studies, psychology (but more accurately parapsychology--'beyond psychology'--pneumatology, monadology, and esoteric philosophical logic,) anthropology and sociology sometimes concentrate their researches on spirituality, but the field remains ill-defined.
In the late 19th century a Pakistani scholar Khwaja Shamsuddin Azeemi started writing books and teaching the somewhat hidden science of Islamic spirituality, of which the best known form remains the Sufi tradition (famous through Rumi and Hafiz) in which spiritual discipline is transmitted to students by a spiritual master or "pir".
