The heart of a vain person cannot be humbled.
When he is corrected or rebuked, he reacts angrily, and when he is praised and flattered he behaves unbecomingly.
Whatever you say to him, he takes in such a way as to become even more swollen with pride. His whole world centers on himself.
On the contrary, the sinner who repents and makes confession transcends himself.
Elder St Porphyrios
