Here we see the Buddha pointing to the Wheel of Dhamma, the one way to escape the terrible turning of the wheel of samsara. He stands at the head of a path leading out from the human realm, to symbolize that that realm is the most favourable for liberation.
The Buddha represents an individual, a human being, who escaped from the wheel by his own efforts. The word "Buddha" literally means "Awake." Awakened, he was free of delusion (ignorance), free of delusion, he was not bound by craving and clinging and the circle of the dependent origination was broken.
