In simple words
The heart line is the top line across your palm, starting under your little finger. Palmistry links it with love and feelings.
How to recognise this one: The top line across your palm sweeps up at its end, finishing between or near your first and second fingers.
What it means
You express what you feel without much hesitation. Affection comes out in words and actions, and when love disappoints you, you tend to recover and move forward rather than dwell. A line ending between the first two fingers points to balance: you care about your own needs and other people's, and you keep your feet on the ground in love.
Growth
Your openness is a gift. Pair it with patience for people who show feeling more slowly than you do; quiet does not always mean cold.
Palmistry is a tradition of reflection, not a medical or scientific reading. Lines change over a lifetime, and no line predicts illness or the length of a life.
