The heart line in Palmistry denotes the expression of a person that is, how well the person can express sentiments, emotions and spiritual development in respect to relationships and compassion. The heart line can either be straight or curved. Palmistry states that heart line is connected with all the emotions of a person`s life that are centered on love. According to the science of palmistry, generally the stronger and deeper heart line depicts stronger and warmer attachments. The single palmer crease or the simian line is the name given to the meeting of head line and heart line. The area of quadrangle between the heart line and head line is lost in such a hand. It denotes the blending of mental and emotional powers of the bearer.

Palmistry based on length and shape of the Heart Line
Different heart lines reflect different emotions. Like for instance, a straight short heart line shows an emotionally cool person, who either bases the relationships on sex, or other practical aspects.

Straight Heart Line: A straight long heart line reaching the middle space beneath mount of Jupiter and mount of Saturn shows a person with warm emotions, but a tendency to put them under constant scrutiny. Spontaneity and display of affections is not that prominent with people with straight long heart line.

A person with heart line running straight across the palm is the kind of person who will spend and dedicate his entire energy in the work at hand. It is also said in palmistry that higher the heart line in the palm, more is the mental peace and fulfillment. For those having a straight heart line display of emotions is not that easy, this part generally takes the secondary place.

Curved Heart Line: Further, when the curved heart line ends underneath the middle finger it means the person is self-centred in relationships and need to have more consideration towards one`s partner. When the heart line is curved and reaches the portion between fore and middle fingers, it means that the person is emotional, warm and passionate.

If the curved heart line ends in the mount of Jupiter, it shows the tendency for love that is highly idealistic, and a bit far from reality. The person is considered as very romantic by nature. More the heart line covers the mount, the more pronounced are these characteristics. Heart line reaching the base of fore finger tends to make the person too possessive, protective and demanding. The curved heart line with fork at the end, with one branch ending in mount of Jupiter and another below finger of Saturn or middle finger shows perfect balance and harmony in the display of emotions
