We can see this inclination in every being. A little plant, a tree, if we suppress its growth, if we erect a fence round it, if we cover it with glass, it will not flourish, it will not produce flowers; in time it will die. Why is this? It is because its life cannot express itself when it is covered, it cannot express itself when there is a fence round it. It is not enough for it to be alive, because life does not want only to live; to realize itself life must be able to make progress, and progress is only made when there is free movement.
