Close your eyes. Imagine that you are in a serene forest , late at night. You reach a small pond somewhere in the forest and a mountain beside it. Imagine a drop of water trickling into the pond and creating a ripple. A ripple which returns back to the source. Now , our minds are akin to such ponds and our thoughts are those small droplets of water which create such ripples which bring back their like. Once we free our minds , we scan select the drops of water which we can put into our minds. Thus , we must strive to free this most sacred asset because the ripples which we create put their dents at a cosmic level.
