The mind is like water; it always flows downwards. Even if waterfalls on the top of a mountain, it will still flow downwards. But fire always burns upward. Even if you turn a flame upside down, it will still burn upwards. It can vaporize and uplift water. So the fire denotes awareness and the water denotes the downward flow of our mind. The mind is always searching for materialistic comforts. We have to awaken the mind with the fire of inner awareness. We have to take a firm resolution to move forward.
