Enter into yourself, live within yourself, in the quiet of your interior self, with a temperate and pure soul, with a calm and humble spirit.
Venerable St. Ephraim the Syrian
Real self-knowledge is the clear vision of one’s deficiencies and weaknesses to such a degree that everything is filled to overflowing with them.
St. Theophanes the Recluse
One who is capable of seeing himself is better than one who has been made worthy to see angels.
Venerable St. Isaac of Syria
Mankind considers it extremely important to know earthly and heavenly things,. But it is far greater to have knowledge of ourselves. The man who is conscious of his personal failings is much more worthy of praise than is he who searches and understands the paths of the stars, but does not know the path to salvation.
Blessed Augustine
