We all know that no two fingerprints are identical. But in fact, the entire hand is unique in its pattern of lines. The lines are unique precisely because each of us has personal memories, hopes and individual character traits. Since there is a traceable link between our personality, thoughts and experiences and the way the lines form on our hands, our handprints represent a kind of personalized signature. Just as we continuously change and evolve, so do the lines on our hands. As our personality matures, our attitudes, priorities, activities and companions may also change. These important changes are all reflected in the hand. A study of our prints provides us with a method of analyzing ourselves objectively. We are, therefore, likely to make more positive choices regarding our work, our dealings with people around us, and many other important aspects of life. We will find ourselves less likely to repeat or perpetuate mistakes. With time, the improvements we make in our lives will register on the hands. The objective is to evaluate a person's character or future by studying the palm of their hand.
