" Impermanence is also seen in the fact that the end of meeting is separation. Our meetings with each other are like mingling in a dream. Yet we often become so intensely entangled in our relationships that separation of one kind or another becomes the source of overwhelming sorrow. The Buddha gave a striking example of this when he said that in the course of countless lifetimes each one of us has shed more tears over the death of loved ones than all of the water in the great oceans. Although feelings of loss and sorrow are natural for most of us, still, the more we contemplate and accept the truth that all meetings will end in separation, the less likely we will be to drown in those waters.
