There is a time for flowers to bloom and a time to wither; when new life breaks through the ground, old things must return to dust. This is the constant law of the world, as irreversible as the changing of the seasons. The alternation of all things in the world is never accidental. Every inch of growth of new things inherits the remaining warmth and nutrients of old things; every end of old things makes space for new possibilities. This law does not only exist in earthly vegetation, but is even more obvious in the world of immortality. Where spiritual roots wither, new sprouts may emerge, and new techniques often emerge after the collapse of ancient formations. Even a monk's realm breakthrough is the shattering of old cognition and the reshaping of new insights.
