Projection is the ability to project one's identity beyond one's physical body, while retaining a connection between the two.
The definition of one's identity is often either an astral projection (i.e. the projection of one's soul from the physical body) or an emotional projection (i.e. the projection of one's emotions). In either form, projection is a powerful ability that allows the person to scout ahead or otherwise gain information without having to physically perform the task.
