Everything you see (except nature) is made by hands! You can do good or bad things with your hand. The decision is made in your brain/mind. But the hand follows your decision. It's crazy. All is connected to the hands. Signing a contract, getting known to someone (shaking hands), writing "I love you". The hand is the greatest tool! In the past, now and in the future. If you are touched by a hand it can feel good. OR. It can feel bad, if the owner of the hand has the intention to hurt you. You can write someone a compliment or put someone down.
