Hand
The hand can symbolize action, conscious will, and human development, as it is through our hands that we physically shape things and influence the world around us. At the same time, the hand helps us communicate with others (which presupposes awareness). To sacrifice one’s hand symbolizes giving up the ego’s power. (Compare Finger.)
Through our hands, we connect with reality and our fellow humans; we can grasp reality, shake hands with others, and so on. There are countless expressions that reflect how we symbolically think about our hands.
