I want creation to penetrate you with so much admiration that everywhere, wherever you may be, the least plant may bring to you the clear remembrance of the Creator.  If you see the grass of the fields, think of human nature, and remember the comparison of the wise Isaiah.  “All flesh is grass, and all the goodliness thereof is as the flower of the field.”  Truly the rapid flow of life, the short gratification and pleasure that an instant of happiness gives a man, all wonderfully suit the comparison of the prophet.  To-day he is vigorous in body, fattened by luxury, and in the prime of life, with complexion fair like the flowers, strong and powerful and of irresistible energy; tomorrow and he will be an object of pity, withered by age or exhausted by sickness.  Another shines in all the splendour of a brilliant fortune, and around him are a multitude of flatterers, an escort of false friends on the track of his good graces; a crowd of kinsfolk, but of no true kin; a swarm of servants who crowd after him to provide for his food and for all his needs; and in his comings and goings this innumerable suite, which he drags after him, excites the envy of all whom he meets.  To fortune may be added power in the State, honours bestowed by the imperial throne, the government of a province, or the command of armies; a herald who precedes him is crying in a loud voice; lictors right and left also fill his subjects with awe, blows, confiscations, banishments, imprisonments, and all the means by which he strikes intolerable terror into all whom he has to rule.  And what then?  One night, a fever, a pleurisy, or an inflammation of the lungs, snatches away this man from the midst of men, stripped in a moment of all his stage accessories, and all this, his glory, is proved a mere dream.  Therefore the Prophet has compared human glory to the weakest flower.
