St. Tikhon of Zadonsk: Learn the sickness of Anger

 And see what anger can do in a man; how indignant and noisy he becomes, how he swears, how he beats his head, trembling as in a fever... Man, learn the sickness of thy soul, for without acknowledgment of illness there is no healing... Christ alone can heal us, who sigh and pray to Him with faith.

+St. Tikhon of Zadonsk, from Works, quoted in Saint Tikhon of Zadonsk, Inspirer of Dostoevsky, by Nadejda Gorodetzky

St. Tikhon of Zadonsk: Pray to God incessantly

 When you wish to live piously and be a true Christian and so be saved, pray to God incessantly and beg help of Him with fervor. Just as according to His love for man God commanded us to pray and ask of Him every good thing, He also promised to give us what we ask for, and most of all what is needful for our salvation.
"Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened." (Matt 7:7-8). Know, beloved, that a Christian without prayer is as a bird without wings and as a warrior weapons.

Pray fervently, then, to Christ the Lord and give yourself to Him for direction, and He will correct and guide you to eternal blessedness according to His love for man. Only be careful and watch yourself, and seeing you care He will help you in everything. Read the Beatitudes, and the rest, often and with fervor.

St. Tikhon of Zadonsk: God's kindness toward man

Now, in accordance with your desire, I shall write about man. But believe me, every time I think about man, I am filled with great wonder because of the kindness of God towards him; so that I exclaim with the psalmist: "What is man that Thou art mindful of him?" (Ps 8:4, 144:3) In truth man is a wondrous being. All God's creation is wondrous, but man above all else. Wondrous is the divine providence concerning him: he is created, not as other beings, but by the special decree of the Holy Trinity: "Let us make man to Our image and likeness" (Gen 1:26). Man is created to God's power, wisdom, and kindness; but man bears in addition God's image within himself. In truth, this is the greatest goodness, the most admirable beauty, the highest honor! Man is inferior to God, but he is above all other created things: man has been honored by God's image: beautiful are the skies, the sun, the moon and the stars, and all things made by God; but man is the most beautiful of all; for he bears within himself a beauty created to the image of God. Think and reflect on the beauty of God, Who is the Uncreated and Eternal Beauty! If God has so greatly honored man, all hell and all the devils, can do nothing to man. God is within him and his protector.
