"Sometimes the roots of a tree may be firmer than the foundations of a house. When the floor starts shaking, wouldn’t it be safer to catch hold of the branch of a tree? The times are so difficult that you may find a branch more secure than the slabs that make up the floor... In the midst of earth tremors, the supple, living branch will not break; that is why you should focus on studying the nature of things. It is silly not to make use of what is growing right by the window. Only a madman needlessly uproots a plant that he himself is unable to cultivate."
