To carry his load without resting, not to be bothered by heat or cold and always be content: these three things we can learn from a donkey

It's not the heat, it's the humidity

It's not the load that breaks you down - its the way you carry it

Its warmth was not heat, and its cool was not cold

I guess it's not the ideal situation, but if he was given that load, I know he could carry it. Once he gets his shoulders square, that's it. He's going forward.

The thing with heat is, no matter how cold you are, no matter how much you need warmth, it always, eventually, becomes too much.
