You wish to be great, begin from the least. You are thinking to construct some mighty fabric in height; first think of the foundation of humility. And how great soever a mass of building one may wish and design to place above it, the greater the building is to be, the deeper does he dig his foundation.
Magnus esse vis, a minimo incipe. Cogitas magnam fabricam construere celsitudinis, de fundamento prius cogita humilitatis. Et quantam quisque vult et disponit superimponere molem aedificii, quanto erit maius aedificium, tanto altius fodit fundamentum.
