No matter how much a person tries to find ways to be happy (money, fame, pleasures, etc.), they will achieve nothing, since happiness is led by virtue and virtue is God Himself and whatever He commands and ordains.

Therefore, reading "Know Thyself" is a valuable aid in an era where the identity of a Christian is, for many, a custom without demands or a matter of taste. A reminder that "the kingdom of God is not for those who sleep and are foolish, but the violent take it by force" (Clement of Alexandria). Saint Nektarios is not interested in writing a literary work; he knows that good teachings are of no use if they do not help you change your life or at least its direction.
