You will be surprised: if you can meditate on sadness, sadness will reveal its secrets to you — and they are of tremendous value. And sadness, once it has revealed its secrets to you, will disappear. Its work is done, its message delivered. And when sadness disappears, joy arises. Joy arises only when sadness disappears out of meditation; there is no other way. Joy wells up when you have broken the ice of sadness that surrounds it. In fact, sadness is like the shell that surrounds the seed; it is protective, it is not the enemy. Once the seed has dropped its protection, is surrendered into the soil, the shell has died, only then the sprout is born.
