The heart line begins under the little finger, also known as the Mercury finger and moves uppermost on your hand, under all the fingers. This is the line which illustrates the degree of sensitivity with which you approach the world as well as tells the story of your personal emotional history.
This is the line which rules a person’s emotional idealism as well as a sense of passion. This line portrays the kind of people that you love and how you love them. When the Heart Line appears lower on the hand, this shows that the heart rules the intellect. If the line is straight primarily, then it shows a person who is the opposite of that, showing a person who is ruled by their intellect and neglects their emotional needs. The heart line often branches out and the way that one understands the branching of the heart line will be helpful in the interpretation factors as is learning where the heart line ends.
Heart Line originates on the percussion edge of the hand from one of four possible main areas (A, B, C or D), and extends toward the opposite side of the hand to one of six possible destination areas. (Shown later)
