The third and fourth levels show the monk making slow but steady progress by clearing the restlessness and dullness that alternately interfere with his concentration. The image of the monk roping the animals indicates his steady mindfulness and vigilance at these stages. But the sudden appearance of a rabbit on the elephant's back indicates the emergence of a 'subtle dullness'. This is a mixed blessing. While the concentrated tranquility gradually stabilizes itself, it also produces an inner ease and ecstasy. This natural sensation imperceptibly lures the mind into a sullen state, robbing the mindfulness of its sharp focus. However, the white patch on the rabbit indicates the steadiness of the concentrated tranquility. This means fewer restless events at these stages.
