Anything we put our trust in, anyone or anything outside ourself, and even our self, will eventually at some point really let us down. Nothing can live up to the expectation we put on the self or others, or things. So the best we can do with trust is, trust in nothing. 

And that’s not so difficult, because it’s not so difficult to trust nothing. Just flip the emphasis on the words: trust nothing. Well, that’s it, we trust nothing, we trust sunyata, emptiness, Buddha nature, faith. We trust that which has no borders and no consistency and no form.   It’s limitless, it’s endless, it’s boundless, it’s eternal.
