The story of the mystics is one of an all-consuming, passionate love affair between human beings and God. It speaks of deep yearning, of burning desire for the contemplation and presence of the divine beloved. Mystics seek participation in divine life, union, and communion with God. Their desire is kindled by the fire of divine love itself, which moves the mystics in their search and leads them, often on arduous journeys, to discover and proclaim the all-encompassing love of God for humankind.
In some religions, prayer is undertaken, not with the intention of influencing a deity, nor with any hope of prayers being directly answered, but in order to produce a harmonious state of mind. Prayer and meditation facilitate integration by allowing time for previously unrelated thoughts and feelings to interact. Being able to get in touch with one's deepest thoughts and feelings, and providing time for them to regroup themselves into new formations and combinations, are important aspects of the creative process, as well as a way of relieving tension and promoting mental health ... Human beings easily become alienated from their own deepest needs and feelings. Learning, thinking, innovation and maintaining contact with one's own inner world are all facilitated by solitude.
