Modern students and teachers think that they can accomplish something
of significance without practicing discipline, but that is not true.
Modern students do not want to discipline themselves, and yet they
search out that which is only attainable with discipline.
Discipline should not be forced on the student but should be
introduced to him. He should understand that discipline is the first
prerequisite for organizing one's internal states.
Discipline is a leader that helps one verify, analyze, and know the
subtler dimensions of life.
