…the first self-conceited one was Satan. A man must never
consider himself greater than others. Rather, he must always be humble and
self-effacing. The bird, as long as it sees itself at a low level, is given
impetus to soar and progress; but the moment it fancies itself high in the air,
it begins to descend.
