I think it's interesting how he says in the last one, "protect and guard the arahants." What could that mean? Does he mean not to oppress them? To recognize them? Maybe in India it was easier for a king to recognize his spiritually accomplished. Also, how does that contribute to a nation's well-being?
I think that the teaching implies that the mystics were the wise ones and therefore they were truly precious, that their wise counsel in matters of government and society should be valued to the utmost, and whenever there's a problems in the affairs of the state or spiritual matters you go to the arahants for counsel.
We've got it backwards here in the West. We put our mystics in jail, torture and put them to death - from Socrates to Jesus Christ, et al. In the West our leaders take counsel from economists, bankers, political scientist and lawyers, etc. - and that's it. It's no wonder we're in deep trouble. The heart and soul of a society should be its mystics. This makes total sense to me.
In the East it's a different matter, it's the other way around. The Buddha was revered by kings and they sought his counsel, built monasteries for him, etc., but that was back in India where they value their mystics. I think a modern example would be the case of Ajhan Chah, the Thervadan monk, who was deeply respected by those in governance in Thailand and they sought out his counsel, and they supported his endeavours financially.
Was there a time when we valued the wisdom of the mystic in the West instead of murdering and marginalizing them? I'm am not a well educated person, so I can't really answer this question properly. But it's in our mythology. We have Arthurian legend, where we have King Arthur being counseled by Merlin, the sage and mystic. Camelot flourished because of this relationship.
