He’s a reincarnation of a living bodhisattva. That’s something that’s hard to over-rate considering what it means. It amounts to him saying “Even if I was completely and totally enlightened and could escape all suffering, I choose to stay in this body on this Earth and help others instead.”
That’s the foundation for what he does in politics, charity work, speaking engagements, etc..
Personally, I’d like to see more people take that stance.
