Laughter is the oonly thing that is special to human beings...not reason, but laughter. Animals can also reason...they reason in their own way. But they cannot joke, they cannot laugh, they cannot see the funny side, that is impossible for them.
Al animals are serious people and all serious people are animals! The moment you get rid of your seriousness you get rid of your animal nature.
Complete laughter is a rare phenomenon. When each cell of your body laughs, when each fibre of your being pulsates with joy, then it brings great relaxation.
There are a few activities which are very valuable: laughter is one of those activities.
Singing and dancing are also of the same quality, but laughter is the quickest.
