All spiritual growth comes from reading and reflection. By reading we learn what we did not know; by reflection we retain what we have learned. The conscientious reader will be more concerned to carry out what he has read than merely to acquire knowledge of it. In reading we aim at knowing, but we must put into practice what we have learned in our course of study.

If a man wants to be always in God's company, he must pray regularly and read regularly. When we pray, we talk to God; when we read, God talks to us.

Tshe suffering of adversity does not degrade you but exalts you. Human tribulation teaches you; it does not destroy you. The more we are afflicted in this world, the greater is our assurance for the next. The more we sorrow in the present, ..the greater will be our joy in the future.

It is agreed that all sound which is the material of music is of three sorts. First is harmonica, which consists of vocal music; second is organica, which is formed from the breath; third is rhythmica, which receives its numbers from the beat of the fingers. For sound is produced either by the voice, coming through the throat; or by the breath, coming through the trumpet or tibia, for example; or by touch, as in the case of the cithara or anything else that gives a tuneful sound on being struck.

War with vices, but peace with individuals.

Letters are signs of things, symbols of words, whose power is so great that without a voice they speak to us the words of the absent; for they introduce words by the eye, not by the ear.

Tolle numerum omnibus rebus et omnia pereunt.Take from all things their number and all shall perish.
