Imitation of Christ

Cum sapiente et sententioso viro consilium habe, et quære potius a melioribus instrui, quam tuas adinventiones sequi. Bona vita facit hominem sapientem secundum Deum, et expertum in multis. Quanto quis in se humilior fuerit, et Deo subjectior, tanto in omnibus erit sapientior et pacatior. 

Take counsel with a man who is wise and of a good conscience; and seek to be instructed by one better than yourself, rather than to follow your own inventions. A good life makes a man wise toward God, and gives him experience in many things. The more humble a man is in himself, and the more obedient towards God, the wiser will he be in all things, and the more shall his soul be at peace.

Imitation of Christ, I, 4:3
