Once I was sitting by a quiet pond. It was so peaceful, my heart was singing. Soon, however, the lawnmower from a nearby house started up. The a leaf-blower chimed in with its raspy roar. A wood-chipper added its clatter to the overwhelming noise. Someone else was in the background with a hedge-cutter, whirring away. Where had the peace gone?
If the peace was not in my heart, and therefore in my mind, it was not anywhere. Peace that is dependent out outside circumstances is not true peace and can be destroyed in seconds. Then we can feel peace even in the midst of an uproar, in a noisy crowd, in a traffic jam.
Many techniques for uncovering inner peace have come to us from the great sages of the past. You can study any number of them. And if one of them leads you to the spot of continuous inner joy and freedom from fear, go with it. But do not look to anything or anyone outside yourself to find that fountain of peace that belongs to everyone.
