What is the indication when the Heart line is absent?

A complete absence of this line is very rare and must not be confused with those cases where the Head and Heart lines are joined in one, forming a bar across the hand: when the Heart line is really absent it is an indication of heart disease, or great weakness of that organ, unless the lines of Life and Health are exceptionally good, when it shows a cold, selfish, avaricious, isolated nature, capable of malignancy and treach­ery, but for this reading it is necessary that other signs of badness should also be present.
