Of every ten who tread the Middle Way to Knowledge there are nine who turn aside through avarice, though not all avarice is born of belly-hunger or the greed for gold. Some seek preeminence, such eminence as they have won corroded by insane pride. So by this mark you shall know the Middle Way, that whoso treads it truly avoids vices, having found them in himself, so that he knows their habit and is temperate in judgment, throwing no stones lest he break the windows of his own soul.--From The Book Of The Sayings of Tsiang Samdup
