Your palm's three major lines — life line, head line, and heart line — have a lot to tell you. They can demonstrate the talents and characteristics a person is born with and how she can bring these to the forefront in everyday activities to create the kind of life she desires. No one knows exactly how these lines are formed, but we do know that they represent far more than just the bending and stretching that our hands go through every day. They are created by the body chemistry in response to what we feel, think, and experience.
