When you put a donut in boiling water, a lot of bubbles will come out until all of the moisture in the donut is gone. It also makes a lot of noise, doesn't it? Finally, all is silent and the donut is ready. The silent condition of mind which comes about through a life of meditation is called peace. Meditation is like boiling the oil. It will make everything in the mind come out. Only then will peace be achieved.
This was a very graphic and precise explanation of spiritual life if I had ever heard one!
