If we take care of the means, we are bound to reach the end sooner or later. When once we have grasped this point, final victory is beyond question. Whatever difficulties we encounter, whatever apparent reverses we sustain, we may not give up the quest for truth.
The seeker after truth should be humbler than the dust. The world crushes the dust under its feet, but the seeker after truth should so humble himself that even the dust could crush him. Only then, and not till then, will he have a glimpse of truth.
