Osho on Laughter
When you really laugh, for those few moments you are in a deep meditative state. Thinking stops. It is impossible to laugh and think together. They are diametrically opposite: either you can laugh or you can think. If you really laugh, thinking stops. If you are still thinking, laughter will be just so-so, it will be just so-so, lagging behind. It will be a crippled laughter.
When you really laugh, suddenly mind disappears. And the whole Zen methodology is how to get into no-mind — laughter is one of the beautiful doors to get to it.
As far as I know, dancing and laughter are the best, natural, easily approachable doors. If you really dance, thinking stops. You go on and on, you whirl and whirl, and you become a whirlpool — all boundaries, all divisions are lost. You don’t even know where your body ends and where the existence begins. You melt into existence and the existence melts into you; there is an overlapping of boundaries. And if you are really dancing — not managing it but allowing it to manage you, allowing it to possess you — if you are possessed by dance, thinking stops.
The same happens with laughter. If you are possessed by laughter, thinking stops. And if you know a few moments of no-mind, those glimpses will promise you many more rewards that are going to come. You just have to become more and more of the sort, of the quality, of no-mind. More and more, thinking has to be dropped.
Laughter can be a beautiful introduction to a non-thinking state.
