What effect could spoil this perfect calm? Is there another challenge for the Fool? In fact, it is his bliss that makes him vulnerable to the illusions of the Moon . The Fool's joy is a feeling state. His positive emotions are not yet subject to mental clarity. In his dreamy condition, the Fool is susceptible to fantasy, distortion and a false picture of the truth.
The Moon stimulates the creative imagination. It opens the way for bizarre and beautiful thoughts to bubble up from the unconscious, but deep-seated fears and anxieties also arise. These experiences may cause the Fool to feel lost and bewildered.
