Having a discipline is not doing an effort which is an aim in itself. Somebody likes to sacrifice himself. But sacrifice is just the opposite state of laziness. We don’t need either.
Having a discipline means to be ready to learn, to be open enough to learn. Humble enough. Therefore it means to be ready to effort to reach someting, even knowing that goal is already here.
Maybe while we are learning something we can suffer, we can fight, we can fall.
Being true is always a risk.
Who is searching for the Self must have enough courage to go into the effort and suffering. Who is requesting a deep state of living, has to accept to leave his own life surface.
