If you cling to one pole, you become afraid of totality. You cannot weep totally, how can you laugh totally? That's why the belly laugh has simply disappeared from the world. You don't know what a belly laugh is - when you not only laugh, but the belly laughs. The whole body vibrates, not only you, but from head to toe everything laughs. That laughter is mad because you are totally in it.
Look at the absurdity of the world: only a madman can be total. You are afraid, because you know well that you have suppressed tears so if you laugh deeply, tears may come. And it happens. You may have noticed many times, if you start laughing deeply immediately you feel tears are coming.
You feel confused - why are tears coming? Tears are coming because you have been suppressing them, and you have never allowed a totality. And now you laugh totally: the suppressed needs expression, the suppressed flows, the suppressed seeks a moment; the door is open - it flows.
