Our culture is so enmeshed in the more, more, more philosophy: work more so you can buy more; the more you have the more you want; get more done, be more productive. Even when we're aware of this unhealthy cycle it is very difficult to break out of it because this how our society operates. We're always thinking of the next thing we need to do and not concentrating on our present moment.
While I was a patient at MGH I had several interesting conversations with one of the RTs who was taking care of me. He was a Buddhist and told me this great little story about staying in the moment: Once there was a man, who, while walking one day came upon a hungry tiger. The tiger started to chase him. He ran, only to find himself up against the edge of a high cliff. What to do? He faced a certain death if he stayed, the tiger would eat him. He decided to jump. As luck would have it as he went over the cliff, about 5 feet down there was a plant growing out of the side of the cliff. He grabbed the branches and hung on for dear life. Growing on the plant he noticed a single red, juicy, sweet strawberry. He picked the fruit, ate it and enjoyed it. The end.
Wait a moment! That's the end? What happened to the man? What about the tiger? Did he survive the fall?
It doesn't matter how the story ends, that's not the point. The point is that he ate the strawberry and enjoyed it. Moral: enjoy what you are doing at the moment, no matter the circumstances. Had the man been thinking about the tiger chasing him, or the fact that he was hanging by a small branch over a large drop he probably wouldn't have even noticed the strawberry. But he was present to his situation, and while he was eating the strawberry, he was fully aware of how it smelled, the color and the taste. He didn't waste what were probably his last few moments alive worrying about his fate and what was to become of him.
I'm sure I'm not expressing the thoughts as eloquently as the Zen RT, but hopefully my explanation makes sense. Pay attention to what you are doing. The end.
