To have a clear understanding of things of importance, seriousness and sincerity are essential. Those who are not serious pay no attention to reasons and justifications. So they are unable to understand the matter at hand. They ridicule it and try to show that it is not worthy of serious consideration. It is not possible to convince such people in any way. They will accept the truth only when their wrong approach brings down upon them overwhelming punishment, from which there will be no escape. Serious people behave quite differently from this, for their seriousness makes them cautious. And they have no trace of arrogance in them. The extreme intensity of their feelings makes them spend sleepless nights: their time is spent in remembering God. They do not consider their wealth the result of their hard work, but take it as a gift from God. That is why they think that others have as much right to a share in it as they themselves.
