The paintings represent the steps that lead to spiritual illumination. The original drawings are by Chinese Master Chino Kukuan, from the XII century; and these from previous Taoist stories. The bull represents the mind, and the animal nature in every human being. The struggle to tame the bull is equivalent to becoming the master of oneself instead of remaining controlled by one’s impulses and emotions. The student can use the images to evaluate his advancement or discover in which stage he is at on the spiritual path.
