In via ruinæ non eas, et non offendes in lapides: nec credas te viæ laboriosæ, ne ponas animæ tuæ scandalum.
Go not in the way of ruin, and thou shalt not stumble against the stones: trust not thyself to a rugged way, lest thou set a stumblingblock to thy soul.
In via de ruina non illas, et non offende in lapides: nec crede te de via laborioso, ne pone ad anima tuo scandalo.
