Where does a spiritual entity reside?

The spirit body, in which a spiritual entity resides after leaving its physical body, has certain functions to perform, like those of the physical body, but these functions are of a cleaner and more wholesome nature, and consist mostly in that of an outer protection—or house in which the spirit can dwell, and in which it can travel about through the spiritual universe. The spirit does not require food, nor drink of any kind, except that which it absorbs from the atmosphere through which it is passing, and in which it dwells.
