A treasure that is known is quickly spent: and even so any virtue that is commented on and made a public show of is destroyed. Even as wax is melted before the face of fire, so is the soul enfeebled by praise, and loses the toughness of its virtue.
Our enemies (demons) fell because of their pride, and call us to follow them, and bring us feelings of praise. And if your soul accepts that praise, then grace will depart, until the soul becomes humble again. And so all your life you must learn the humility of Christ.
How harmful is the praise of man! Even though a person may have done something worthy of praise, when he enjoys the sound of praise he is already deprived of future glory, according to teachings of the holy fathers.
A mind from which the thought of God has been carried away and which has thus become far removed from remembering Him, is also indifferent to sin with the outer senses. For such a mind can guide neither the hearing nor the tongue, since zest to work on itself has gone out of it.
