On one occasion, the Buddha said to the monks this:
"No other form do I know, O monks, that so persists in obsessing the mind of a man as the form of a woman. The form of a woman persists in obsessing the mind of a man.
"Man is unhappy because he doesn't know he's happy. It's only that. That's all, that's all! If anyone finds out he'll become happy at once, that minute.... It's all good. I discovered it all of a sudden."
Most recently I was sitting zazen at a local park. It was a most beautiful day. I was intent of meditating. But was constantly distracted by my thoughts. The longer I meditated the more agitated I became. I finally stopped. Then I looked around me--the trees were changing color, a white swan was sitting on the lake, a seagull was flying over head, the wind was gently dancing in the leaves. In my desire to meditate I missed all of this. I let go of the desire for what was not--and simple basked in the beauty that was. I was already happy to be in such a beautiful day in such a beautiful setting at such a beautiful moment. My agenda kept me from realizing it.
