Spirituality is a state of evolution of "self" where the difference between an individual with rest of the human-kind is lost. Once he becomes "one" with the rest of the mankind, that is state of highest spiritual evolution. At this point "spirit" of the man becomes one with the supreme "Spirit".

Spirituality, in a narrow sense, concerns itself with matters of the spirit. The spiritual, involving (as it may) perceived eternal verities regarding humankind's ultimate nature, often contrasts with the temporal, with the material, or with the worldly. A sense of connection forms a central defining characteristic of spirituality — connection to something greater than oneself, which includes an emotional experience of religious awe and reverence. Equally importantly, spirituality relates to matters of sanity and of psychological health. Like some forms of religion, spirituality often focuses on personal experience.

Spirituality may involve perceiving life as higher, more complex or more integrated with one's world view; as contrasted with the merely sensual.
