The choice of hand to read is ultimately up to the instinct and experience of the practitioner. The left hand is controlled by the right brain (pattern recognition, relationship understanding), reflects the inner person, the natural self, the anima, and the lateral thinking. It could even be considered to be a part of a person's spiritual and personal development. It is the "yin" of personality (feminine and receptive). As opposites are, the right hand is controlled by the left brain (logic, reason, and language), reflects the outer person, objective self, influence of social environment, education, and experience. It represents linear thinking.
