Contrary to popular belief I always go with the dominant hand. So if you are right handed, read the palm of the right hand. If you are left handed read the left palm. Beware the old wives tales on how to read your palm that are out there. Like for females use right palms for revealing the future and left for revealing qualities you incarnated with. And then the opposite of this for males, and the dominant palms for past and non dominant palms for future. Some palm reading books say palm lines of the left hand shows characteristics you chose for the present incarnation; such as - strengths and weaknesses, and life lessons. And the right hand lines reveal how you put possibilities into play.
