Humility
A little knowledge is a dangerous thing, for the devotee may feel vain and self-satisfied, falsely assuming he is what he knows. There is a proverb that pride goes before a fall. A self-admiring person is apt to refrain from further effort.... Only he who is free from the sense of self-importance becomes richer and richer in spirituality until he is one with God.
