To experience the rose blossom, we must give up the rosebud

One state of evolution, one state of development is followed by another one.

But we cannot have them both at the same time. In the same way that infancy is followed by childhood, then by adolescence, and then by adulthood, the rosebud is transformed into the rose blossom.

We cannot have all stages of development at the same time. One inevitably gives way to the other.
