Spirituality is matters of the spirit, a concept often but not necessarily tied to to a spirit world, a multidimensional reality and one or more deities. Spiritual matters regard humankind's ultimate nature and purpose, not as material biological organisms, but as spirits or energy with an eternal relationship beyond the bodily senses, time and the material world. The spiritual is contrasted with the physical, matter and the temporary. A sense of connection is central of spirituality — connection to a reality beyond than the physical world and oneself, which may include an emotional experience of awe and reverence. Spirituality may also include the development of the individual's inner life through practices such as meditation and prayer, including the search for God.
