the fool has no experience and all experience, they know there is nothing to fear, it's all illusionary and all very real at the same time. the fool steps into the abyss with enthusiasm because the abyss is where it starts, where it ends and where all things reformat themselves like an eternal now. 
the fool is the baby who comes in /out knowing and the dying old man who comes out / in knowing. the secret of the fool is to maintain the fool type qualities through life, that really is living in joy, enthusiasm and celebration because it's all just beyond rationality, logic and reason. 
it's one beautiful experience and the real pleasure is in sharing it even though the fool is alone.
