Rivers of Change

 "We need to learn to see our physical form as a river.  Our body is not a static thing─it changes all the time.  It is very important to see our physical form as something impermanent, as a river that is constantly changing.  Every cell in our body is a drop of water in that river.  Birth and death are happening continuously, in every moment of our daily lives.  We must live every moment with death and life present at the same time.  Both death and life are happening at every instant in the river of our physical body.  We should train ourselves in this vision of impermanence." 
-  Thich Nhat Hanh, You Are Here, 2001, p. 27

In many ways Changes, cycles of birth and death, being a living-moving-acting being ... is what creates endurance, persistence, homeostasis, staying alive.  When Change stops, then we die.  Impermanence is indicative of being alive, existing, being real.
