The understanding of vanity is the most fascinating vision of the phenomenon of life. What the Sufi calls wine is the pleasure he derives from it. When this phenomenon is disclosed to him and he sees what activates all the different lives, it is almost like wine. What Omar Khayyam has called wine is the amusement one gets by looking at the phenomena of life, which lifts one above the worries of life. One will always find that the most evolved sages can be amused; that is why they are pleasant to meet and to speak to. Worrying comes from self-pity and fear; and fear is made of the clouds of ignorance; the light will dissolve it. Humor is the sign of light; when the light from above touches the mind it tickles the mind, and it is the tickling of mind which produces humor.
