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.
Isidore of Seville

Nothing exists without music, for the universe itself is said to have been framed by a kind of harmony of sounds, and the heaven itself revolves under the tone of that harmony.
Isidore of Seville
3.
Confession heals, confession justifies, confession grants pardon of sin, all hope consists in confession; in confession there is a chance for mercy.
Isidore of Seville

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.
Isidore of Seville

The more you devote yourself to study of the sacred utterances, the richer will be your understanding of them, just as the more the soil is tilled, the richer the harvest.
Isidore of Seville
6.
Teaching unsupported by grace may enter our ears, but it never reaches the heart. When God's grace does touch our innermost minds to bring understanding, then his word, which is received by the ear, can sink deep into the heart.
Isidore of Seville

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.
Isidore of Seville

Prayer purifies us, reading instructs us. Both are good when both are possible. Otherwise, prayer is better than reading.
Isidore of Seville

We, as Catholics are not permitted to believe anything of our own will, nor to choose what someone has believed of his. We have God's apostles as authorities, who did not themselves of their own wills choose anything of what they wanted to believe, but faithfully transmitted to the nations, the teachings of Christ.
Isidore of Seville
10.
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.
Isidore of Seville

Baptism is not the work of man but of Christ, and this sacrament is so holy that it would not be defiled, even if the minister were a murderer.

Mary means enlightener, because She brought forth the Light of the world. In the Syriac tongue, Mary signifies Lady.

War with vices, but peace with individuals.

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

In the active life all the vices are first of all to be removed by the practice of good works, so that in the contemplative life a man may, with now purified mental gaze, pass on to the contemplation of the Divine Light.
Isidore of Seville

The name of medicine is thought to have been given from 'moderation', modus, that is, from a due proportion, which advises that things be done not to excess, but 'little by little', paulatim. For nature is pained by surfeit but rejoices in moderation. Whence also those who take drugs and antidotes constantly, or to the point of saturation, are sorely vexed, for every immoderation brings not health but danger.
Isidore of Seville

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.
Isidore of Seville
18.
Number is divided into even and odd. Even number is divided into the following: evenly even, evenly uneven, and unevenly uneven. Odd number is divided into the following: prime and incomposite, composite, and a third intermediate class (mediocris) which in a certain way is prime and incomposite but in another way secondary and composite.
