OSHO

” Try to understand the mechanism of laughter and how it happens. If I tell a joke, why do you laugh? What makes you laugh. What happens? What is the inner mechanism? If I tell a joke expectation is created. You start expecting. Your mind starts searching for what the end will be. And you cannot conceive the end. ”A joke moves in two dimensions. First it moves in a logical dimension. You can conceive it. If the joke goes on logically to the very end, it will cease to be a joke; there will be no laughter. So suddenly the joke takes a turn and becomes so illogical that you cannot conceive it. And when the joke takes a turn and the result becomes illogical; then the expectation, the tension that was created in you, suddenly explodes. You relax. Laughter comes out.

”Laughter is needed for you to exist. Otherwise, you will commit suicide

A monk asked Joshu: "What is the Buddha?" "The one in the hall." The monk said, "The one in the hall is a statue, a lump of mud." Joshu said, "That's so." "What is the Buddha, then?" asked the monk again. "The one in the hall," said Joshu.

"I don’t say anger is wrong, I say anger is energy, pure energy, beautiful energy. When anger arises, be aware of it, and see the miracle happen. When anger arises, be aware of it, and if you are aware you will be surprised; you are in for a surprise – maybe the greatest surprise of your life – that as you become aware, anger disappears. Anger is transformed." -OSHO  from Emotions.
