It is not true that the up cycle is good and the down cycle bad, except in the mind's judgment. Growth is usually considered positive, but nothing can grow forever. If growth, of whatever kind, were to go on and on, it would eventually become monstrous and destructive. Dissolution is needed for new growth to happen. One cannot exist without the other.
