Palmistry or the study of Hand is a science with which one can find out the good and bad aspects of his life, palmistry, a science which originated in India and later became popular in the world, is a branch of Jyotish Shastra or Vedic Astrology.
In Palmistry, both hands play a major role, the lines in the Left hand of the person denotes what he received on the basis of good deeds in past life, and the right hand denotes the residual (Good Deeds + Bad Deeds) or the actual luck of the person. This is the reason why some of your lines in Left Hand are not same as in your Right hand. You may say that Left Hand is the Gross Profit and Right Hand is the Net Profit.
