Our emotions are there to guide us, not control us.

Where would there be leather enough to cover the entire world? With just the leather of my sandals, it is as if the whole world were covered. Likewise, I am unable to restrain external phenomena, but I shall restrain my own mind. What need is there to restrain anything else?

Well, assuming we’re not in real danger and we don’t need to take action to protect ourselves … often the best practice is an internal shift rather than trying to change the other person’s behavior.
