There you are again. The 'best' has made its appearance. I think hyperbole is the term in poetry when exggeration is used to make a point. You are not allowed to say 'But...but...in that last poem, you said that something else was the best.'. People will groan and look at you as though you just crawled out from under a stone and did not have the grace to stay unnoticed.
So, NOW, Tiru says...
Aatruvaar aatral igazhaamai potruvaar potralul ellam thalai - Tirukkural
The chief safeguard against ill is for the guardians to never slight the powers of those capable of implementing their will - Loose translation
In other words, the leaders/kings who have the responsibility of safeguarding the well-being of their community/nation need various measures to do their duty of guarding against ill. The foremost of those measures is to keep capable people happy by not insulting their abilities. Because, without those people applying their efforts, how are the other measures to be implemented?
So, yeah, one of the foremost abilities of leadership is delegation. AND for delegation to work you need capable people to whom you can delegate the work; and for those capable people to continue to be trustworthy and diligent you need to ensure that they know that you know their abilities and appreciate them. Failing which, you will lose their diligence or their presence itself.
Whether or not it is the best safeguard against ill befalling you and your community, I leave it to you.
