I loved this quote and explanation I heard in my daily calm meditation app this weekend.

“Where would I find enough leather to cover the entire surface of the earth?

But with leather soles beneath my feet, it’s as if the whole world has been covered.

Likewise, it’s not possible for me to restrain the external course of things,

but should I restrain this mind of mine, what would be the need to restrain all else?”

We don’t have control over all else but do have control over our self.

We don’t need to cover the world with leather, instead, we toughen the leather on 

our own feet so that we are more resistant to it.

-Shantideva, 8th Century Indian Buddhist Monk
