Book One Chapter VI Of inordinate affections
Whenever a man desireth anything inordinately, straightway he is disquieted within himself.
The proud and the covetous are never at rest; the poor and humble in spirit pass their life in abundance of peace.
The man who is not yet perfectly dead to self is soon tempted and overcome in little and paltry things.
He that is weak in spirit, and in a certain manner as yet carnal, and inclined to things of sense, cannot without difficulty sever himself wholly from earthly desires.
And therefore he often sad when he does withdraw himself; and besides, he is easily moved to anger if anyone thwarts him.
And, if he have pursued his inclination, forthwith he is burdened with remorse of conscience for having gone after his passion, which helpeth him not at all to the peace he looketh for.
It is by resisting the passions therefore, and not by serving them, that true peace of heart is to be found.
Peace, therefore, is not in the heart of the carnal man, nor in the mn who is devoted to outward things, but in the fervent and spiritual man.
The peace of the soul, next to the grace of God, is the greatest of blessings, and we should spare no pains to maintain it within us. But we can neither obtain nor preserve this peace of the soul but by resisting our passions and irregular desires; for the more we endeavour to satisfy them, the more restless do they make us; the more we fight against them, the less trouble do they give us; the more we resist them, the more do they leave us in peace.
Give us, O Lord, this interior peace, this repose of conscience, this tranquility which raises our confidence in They goodness, and makes faithful in corresponding with it: this peace of God which surpasseth all understanding, which keeps our minds and our hearts in Thy love, and which Thou alone canst give. Calm the storms and emotions of our passions, by giving us courage to overcome them. Grant that our desires may become submissive to reason, our reason to faith, and the whole man to God. Amen
“Turn to the Lord with all your heart, forsake this sorry world, and your soul will find rest.”Thomas Kempis
Thomas à Kempis
’That gentle and anxious Augustian’ as one of his translators called him 
Thomas à Kempis (1379-1471) was born in the town of Kempen along the Rhine, within the Holy Roman Empire, now part of modern Germany. His family name, Hemerken (meaning little hammer), reflected his father’s trade as a blacksmith. His mother was a school mistress.
At the age of twelve, while learning Latin in Deventer, Thomas became familiar with the Brethren of the Common Life, a lay monastic community founded eighteen years earlier by Geert Groote and Floris Radewyns. The pair had been the catalyst for a widespread spiritual renewal, known as the Devotio Moderna (Modern-Day Devout), calling for a rediscovery of the simple apostolic faith. In 1406, after leaving school, Thomas followed his brother Jan into the Augustinian monastery of Mount St. Agnes, a Brethren congregation in the nearby city of Zwolle. Except for a brief exile, Thomas spent the remainder of his long life there.
In an age of clerical corruption, the Brethren devoted themselves to holiness, challenging laity and priests alike with their authentic piety. They founded schools, served the poor, taught the Scriptures and copied manuscripts. As Thomas was educated, he spent most of his time in the latter exercises and personally copied the Bible no fewer than four times.
In the course of instructing novices, he wrote four booklets which were later combined and published anonymously in 1418 under the title of the first: On the Imitation of Christ. Its central themes are devotion to God, humility, contempt of the world, and meditation on the sufferings of Christ. The work also serves as a brief manual on the monastic life—especially a kind of interior monasticism, unconcerned with outward appearances, but rather with ‘the transformation of one’s way of life’. 
The success of the Imitation was both immediate and enduring so that by the 18th century no book, apart from the Bible, had been translated into more languages. 
It remains to this day perhaps the most widely read Christian devotional and a classic expression of the Devotio Moderna. Thomas authored many other works including biographies on de Groote and Radewijns (who was his spiritual father).
As Thomas’ reputation grew many sought him for spiritual guidance, but he avoided all visitors as far as courtesy would allow. The conversation for which he longed best is described in the 2nd chapter of book three of the Imitation. Toward the close of his life, he wrote, ‘I have sought rest everywhere, but I have found it nowhere except in a little corner with a little book.'
Thomas died at the venerable age of 92. The Brethren remembered him as a ‘kind man, in love with Christ, a comforter to those in temptation and trouble’.
