Bi-location, (also known as dual omnipresence) occurs when an individual or object is located, or appears to be located, in two distinct places at the same instant in time. The way of leaving the body that I am least familiar with involves the subtle shift in attention away from the senses and concentration on some non-sensory image or state. The thing that distinguishes this from normal imagination is the uninterrupted or continuous nature of the inner experience and its clarity or three-dimensional quality. In this kind of spiritual travel, the experiencing person can instantaneously shift back to the physical senses with no resistance or time required to regain normal waking sensory experience.
