Well, I don’t know what kind of meaning the OP was looking for but I saw the potential for serious answers in two areas:
Is it common or uncommon for the lines on both hands to be essentially the same. Mine are similar but also significantly divergent in certain areas. I was made curious to know if there might be a standard other than what I’d expect.
If there is a standard, does deviation from that standard indicate anything. Not does it mean I’ll find riches in my uncles attic, but is it an indication of a particular genetic setting, and indication of long term differences in use (honestly never thought about it so I’m not entirely sure what causes ir impacts the specific of palm lines).
Your future is in your right hand, and your past lies in the left.
The left hand also shows what you were born with (things you can’t control), and the right hand shows what you’re going to make of your life. (things you can)
I have a grid pattern on my palms from burning my hands on a heating grate at my grandparents house when I was just learning to crawl. They’ve continued to grow as I did, and the pattern is now about 5x larger than the original grate pattern is.
I also have a nice perfectly V shaped scar from jumping over a chain link fence. The bent down spikes twisted under the skin, caught, and ripped as I fell to the other side.
There is another on the other palm that is a straight line from sharpening arrowheads a bit too enthusiastically. Stone sharpened heads don’t heal nearly as well as razor sharp heads(that line is gone).
My palm lines are very geometric. Does this mean anything?
