In the spiritual life there are three degrees: the first may be called the animal life; this is the life of those who run after sensible devotion, which God generally gives to beginners, to allure them onwards by that sweetness to the spiritual life, just as an animal is drawn on by a sensible object. The second degree may be called the human life; this is the life of those who do not experience any sensible sweetness, but by the help of virtue combat their own passions. The third degree may be called the angelic life; this is the life which they come to, who, having been exercised for a long time in the taming of their own passions, receive from God a quiet, tranquil, and almost angelic life, even in this world, feeling no trouble or repugnance in anything.  Of these three degrees it is well to persevere in the second, because the Lord will grant the third in His own good time.

— Saint Philip Neri (1515-1595)
