Palmistry is the science of foretelling the future through the study of hands. The structure of various organs such as the hands, feet, nose, eyes, and so on can be used to accurately predict a person's temperament, future, positive and negative factors in marine science. Astrology also explains how to make horoscopes from the palm of one's hand. The mountains on the hand, the color of the hand, the touch of the hand, the color of the nail, the texture of the hand, the signs on the hand, and so on can all be used to predict the future. This science, which originated in India, later spread to Western countries and was illuminated by scholars such as Cheiro.
