Of the four major lines, the heart line is the one people cover with a thumb before they show you their hand. It runs across the top of the palm, starting under the little finger and travelling toward the index finger, and it describes the emotional life: how you love, how you show it, and what you do when it goes wrong. It is also the line most often misread, because people look for a verdict on their marriage when the line is describing their temperament.
Where does it end?
The ending point is the first thing to look at. A heart line that reaches all the way to the base of the index finger belongs to someone who loves with high expectations and needs a partner they can admire; it is often found in Leo and Aries hands. A line ending between the index and middle fingers is the balanced ending: warm, realistic, able to give and to receive. A line stopping under the middle finger describes a person who is private about feeling and may seem cool, though the feeling is there. A very short line that barely leaves the mount of Mercury under the little finger belongs to someone who keeps love in a separate compartment from the rest of life.
Curved or straight?
A curved heart line rises toward the fingers, and a curved line is an expressive one: the person says what they feel, sometimes before they have decided whether to. A straight heart line runs level across the palm and describes someone who thinks about their feelings before acting on them, and who shows love through reliability rather than declarations. Neither is better. A curved line paired with a straight head line makes a person who feels strongly and manages it well; two curved lines make a romantic.
Depth and colour
A deep, clear, slightly reddish heart line is the palmist's ideal: strong feeling, steadily expressed. A faint or pale line suggests someone who has put emotion aside, often after a period of hurt. A line that is deeper in one stretch than another shows a period of life, read from the little-finger end outward, when feeling ran higher than usual.
Breaks, chains, islands and forks
- A break marks an emotional rupture, a loss or a separation. If the line resumes cleanly afterwards, the person recovered; if it resumes lower or fainter, the loss changed them.
- A chained line, made of small linked loops, belongs to someone whose feelings are changeable and easily bruised, often a Cancer or Pisces trait.
- An island, a single small loop, marks a period of emotional confusion or a relationship that was hard to leave.
- A fork at the end, especially a three-pronged one under the index finger, is a good sign: it shows a person who can love in several ways, as partner, parent and friend, without confusing them.
- Small lines rising from it are attachments that lifted the person; small lines falling from it are disappointments.
The heart line and the head line together
The gap between the heart line and the head line is where a reader looks for how a person balances feeling and thought. A wide gap means an open, easygoing nature; a narrow gap means someone who takes things seriously. When the two lines merge into one, the simian line, the person cannot separate the two at all, and pursues whatever they care about with total intensity.
What it does not tell you
The heart line does not say when you will marry, how many partners you will have or whether a particular relationship will last. Those questions belong, if anywhere, to the small marriage lines on the edge of the palm under the little finger, and even there a good reader speaks of tendencies rather than events. What the heart line does reliably show is the pattern you bring to love, and that is worth knowing, because patterns can be worked with. Venus rules affection in astrology, and a Venus stone such as opal or kunzite is the traditional support for a heart line that has been through too much.
