I have lived 37 years and the lines on my hands have changed a great deal in this time. I believe that the lines on your palm/hand reflect your current attitude towards the energies around you. This is an important statement... If you change your attitude... the energies may not change, but how you interact or react to the energies, your attitude, will infulence your destiny or life path, thus changing the lines on your hand. Think of palm reading as looking into the mirror, but a spiritual mirror. Yes lines on your hand do change... also there is the universal effect of energy... what I call the tsunami effect. Sometimes we can be overwhelmed by powerful energies in our lives... which will be reflected by lines on our hands. Sometimes we feel like a person lost at sea... as if hit by a tsunami. BUT our inner strength can be like a boat which allows us to ride the wave. We just need to introduce certain practices in our lives that allow us to express or know our inner strengths, thus we will weather the storms better.
