The way I see it is that all living systems inevitably grow in complexity until they decay and die. This is their nature. As we are part of the system we can't help feeling trapped when the decay and pain is creeping in, but if we can take a larger (Taoist) look at the processes and flow itself then we can find peace as well as our own place within that flow.

By letting go we can achieve the greatest well-being for ourselves and others. We can perform our work and step back, letting things be as they are. The only way they can ever be.
