This portion applies to the following palm and the portion is copy pasted from.
Palmists interpret this line to represent matters of the heart, that is, more literally, our emotional living; it is therefore believed to be an insight into how the emotional sides of our mindframes will act out and be acted upon during our lifetimes, and often said, to what extent we possess emotional reservoirs within us, for example, a chained or gridded heart line (or emotional line) is often seen in people who are highly strung, nervous and draw upon emotional strength and insight to attain their ambitions, i.e. they wear their 'emotions' on their sleeves, often to draw strength. Such chaining or gridding on the heart line (emotional line) is often seen in intensely creative artists such as musicians and writers, as well as deeply driven scientists. Dealing with emotions, the line is also claimed to indicate romantic perspectives and intimate relationships, again, a chained or gridded heart line is said to point to a flirtatious attitude to love, and one which can be prone to fall in love easily. On a physical level, the heart line is indirectly associated with heart health, more so through the effects that emotions can have on the body such as with blood pressure. A chained heart line is often associated with high blood pressure, but also of an 'adrenaline junkie' attitude in life.
