The above mentioned three episodes of Zelgharnine's history, includes many useful lessons for us to learn, some of which are as follows:ِ

1- In this material world, no work can be done, and nothing can be made, without the use of necessary means, apparatus, and instruments.

2- the sun will not set in a dark muddy water, but a great personality may fall or set in a slimy swamp of sin and mistake. A piece of cloud may cover and conceal the glory of the sun, and in the same way, a sin, a slip, or even a mistake, may spoil reputation of a great man.

3- No ruler can rule well without punishing the evil doers, and rewarding the righteous subjects with utmost justice, and this is why Zelgharnine said:ِ

      ``As for he who has oppressed, I shall soon punish him....but as for he who believed and did righteous deeds, for him shall be good reward...''

4- Imposing heavy duties, and heavy taxes upon the subjects, will decrease the governor's popularity and lawfulness.

5- See that Zelgharnine listened and gave ear even to the people who knew not to speak, and could not express their feelings easily, and so should be a good and just ruler.

6- secyruty and safety is the first aid, and the most important necessity of life, which the ruler should give it the needed priority. Therefore, the ruler should construct the greatest barrier against the corruptors and evil doers of the land.
