En lector, librum damus vere aureum, planeque scholasticum, quo continentur haec

Compare the shadows and wheels, and the sad and happy things of this life. For just as shadows do not remain, so they are turned as a wheel.
Always strive to progress in God: for adding a little to a little, in a short time you will collect riches sought by all.
If you wish to escape the molestation of punishment, never affect anyone with reproaches. For by this, God is exasperated.
If you wish to expel every scourge from your house, do not pursue a fellow human with curses: for the God who created him is rightfully provoked to anger.
If you wish to be superior to every sin, do not curiously inquire into the affairs of others: for there are many in you, regarding which you hold another as suspect.
Flee pride, O man, even if you are rich: lest by chance you have God against you.
Love humility, even if you are great: so that you may be exalted in the day of judgment.
Do not seek to attack a man with cavils, and you will not incur reproach in all your life.
When you are in church, do not be lifted up: for those standing before a king neither laugh nor are proud.
Do not hold your life negligently, nor act rashly against the law: lest by acting against the law, you incur destruction.
Be mindful of these precepts with all study, so that they may render you clear in life. Emulate a pure life, so that you may have free power to rebuke sinners.
Drive contumacy away from you, and do not rebuke anyone (rashly) lest you be condemned as being inflated with arrogance.
Do not laugh at another’s misfortune, lest you be laughed at by those you do not wish.
Observe these admonitions, so that they may procure a crown of glory for you.
Be an observer of these precepts, so that they may make you clear to men, and acceptable to God: for thus God is affected with joy, and God is worshiped by such works.
Always strive to progress in good works: for the flight of life is a path to good and compendious virtue.
It is necessary for one burning with the desire of incorruptible things to count as nothing those things subject to corruption.
If you desire the life which is truly life, always expect human death, and pursue the present life with hatred. For you see that the wheel is ceaselessly turned.
Do not desire goods whose use passes away, and whose possession perishes.
