For long stretches a species remains essentially unchanged and then, during a brief period, there is rapid development to a new species. The conditions for this may be the isolation of a part of the population or some new factor that affects the entire population. Change is painful, disruptive and dangerous.
Stability is pleasant and nourishing.
We have suffered the curse of living through the most rapid and dramatic changes in history. It is extremely difficult to adapt to such rapid change. We have no choice. We crave stability but we cannot reach stability until we go through the disequilibrium of this time. The stability that we move towards must be more broadly based then our consciousness is today.
