You are startled at perceiving the bull and then, because there is no longer any mystery, you wonder if it is really there; you perceive its insubstantial quality. When you begin to accept this perception of non-duality, you relax, because you no longer have to defend the existence of your ego. Then you can afford to be open and generous. You begin to see another way of dealing with your projections and that is joy in itself, the first spiritual level of the attainment of the Bodhisattva.
