Personal lines relate to self-knowledge. They show how individual life paths unfold in two dimensions on a flat surface. They can be discovered by anyone who practices introspection and curiosity, through a process involving multiple trials, errors, and adjustments.
Here are a few examples: in an personal line, the endpoints (starting and ending points) may be the places of birth and current place of residence of the same person, or the places of residence of a single individual at two different stages in their life. Personal lines may also connect a significant event in the observer’s life with their physical location when they do their research. When meaningful, the midpoint or midpoints crossed by the line will shed particular light on the question being asked or on the initial intuition.
