Discipline is the key to any success, whether athletic, academic, or spiritual.
An athlete who does not give up the comforts of life will not become a top athlete.
A student who does not give up playing to study will not pass the big exams.
The same is true for the spiritual life.
Only those who are honest with themselves and proceed to remove every bad habit with the tweezers of introspection will become knowers of their souls.
