The answer depends on which palm reading approach you’re using. One school of thought thinks it is best to read only the dominant hand (your writing hand) because this is considered to be your active hand and may have more lines to read than your non-dominant or “passive” hand. Check your own hands to see if this is the case. It’s the approach this article has adopted. However, there is another school of thought that says it is important to read both hands, as the left hand reveals your potential (what God or the universe has blessed you with, such as talents, abilities, etc.), while the right hand reveals what you’ve achieved from that potential (what you have acted on, made the most of, done with your life so far, etc.). You’ll need to make the decision for yourself which approach fits best.
