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.

~ Hazrat Inayat Khan
