Quality of the lines on your hand The quality of all the lines on your hand is important because it strengthens or weakens the functions they represent.     A deep, well-defined line is an excellent indication.     A thin line is not defective but does reduce its strength.     A shallow line weakens the good qualities.     Broken lines indicate major problems during the duration of the break, although the results are not so serious if they overlap.     A chained line dissipates its strength and significance.     An island indicates problems at the age which corresponds with its position on a line.     A fragmented line is defective.
