Laughter brings some energy from your inner source to your surface. Energy starts flowing, follows laughter like a shadow. Have you watched it? 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. And the beauty is…. There are methods — for example, you can concentrate on a flame or on a black dot, or you can concentrate on a mantra, but the greater possibility is that by the time the mind is disappearing you will start feeling sleepy, you will fall asleep. Because before the mind disappears there open two alternatives: sleep — sushupti — and samadhi: sleep and satori.
