“This is worth considering. It is significant. The first thing to understand is that except for man, no animal is capable of laughter. So laughter shows a very high peak in the evolution of life. If you go out on the street and see a buffalo laughing, you will be scared to death. And if you report it, then nobody will believe that it can happen. It is impossible. Why don’t animals laugh? Why can’t trees laugh? There is a very deep cause for laughter. Only that animal can laugh which can get bored. Animals and trees are not bored. Boredom and laughter are the polar dualities, these are the polar opposites. They go together. And man is the only animal that is bored. Boredom is the symbol of humanity. Look at dogs and cats; they are never bored. Man seems to be deep in boredom. Why aren’t other animals bored? Why does man alone suffer boredom? “The higher the intelligence, the greater is boredom. The lower intelligence is not bored so much. That’s why primitives are happier. You will find people in the primi-tive societies are happier than those in civilized ones. Bertrand Russel became jealous when for the first time, he came into contact with some primitive tribes. He started feeling jealous. The aboriginals were so happy, they were not bored at all. Life was a blessing to them. They were poor starved, almost naked. In every way, they had no-thing. But they were not bored with life.
