There are those who seek knowledge for the sake of knowledge; that is curiosity. There are those who seek knowledge to be known by others; that is vanity. There are those who seek knowledge in order to serve; that is Love.
Bernard of ClairvauxLet us affectionately love His angels as counselors and defenders appointed by the Father and placed over us. They are faithful; they are prudent; they are powerful; Let us only follow them, let us remain close to them, and in the protection of the God of heaven let us abide.
Bernard of Clairvaux
