Life follows the model of the Kabbalah's Tree of Life. The Tree of Life identifies 22 Paths in life that connect between 10 States of Being. Each of us is on our own path travelling from one state of being to another.
If you understand which Path that you are on and the meaning of the states of being that you are travelling from and to, then you can maybe start to comprehend the meaning of your life and the purpose you are intended to pursue.
Look closely at the two animals that lead his chariot, one black and one white that represent the dual energies and opposing forces of life. There are no reins that connect the chariot rider to the animals, he must maintain control through the power of his mind.
