American culture places meaning in a handshake. A palm reader would tell you to pay attention to the energy surrounding you during this contact. A palm reader looks at key marks and lines on the palm. The main lines are the Heart Line, Head Line, Fate Line and Life Line. Traditional palm reading would have your passive hand - the hand you don't use to write - be indicative of your innate self, your potential. This hand's lines remain unchanged. And, the active, dominant hand is the one that changes to reflect your achievements in growth. Although, nowadays, palm readers believe the lines on both hands are dynamic, and each hand influences the lines on the other.
