A spirit is a force that influences the will of people. A spirit can be an anonymous force responsible for the atmosphere in a meeting of people, or for the mood within a person, it can also be as personal as the spirit of other people who shape our daily actions. It is called a spirit because it relates not to matter but to mind, soul, and feelings. Spirits can be loving, harmless or dangerous, fleeting or powerful, discreet or haunting, helping or hurting. They can inhabitate places, memories, books, or people.
