When you start your meditation, picture a beautiful blue sky without any clouds in it. Feel that your body is growing lighter. Visualize that you are floating in the sky and that all tension, fatigue, worry and problems have left you.
I felt like I had lost something. But not something silly, like my keys or my gum; more like my arm or my foot, something that really mattered. Like something that I could live without, but would make life much harder if it were missing. And life is hard enough. Life is hard enough with everything we're given.
