Humility is the foundation of all the other virtues hence, in the soul in which this virtue does not exist there cannot be any other virtue except in mere appearance.
All humans are dead except those who have knowledge; and all those who have knowledge are asleep, except those who do good deeds; and those who do good deeds are deceived, except those who are sincere; and those who are sincere are always in a state of worry.
The deeper that sorrow carves into your being, the more joy you can contain... When you are joyous look deep into your heart and you will find that it is only that which has given you sorrow that is giving you joy.
