What if you are trying to help someone and they don’t get it that makes you angry? Where does self-cherishing come in this case?

That is a great question. Let’s say for example, you give some money to a homeless person to get some food. They turn around and buy liquor or cigarettes with that money. If that happens you get angry because you think they are not conforming to your values. You have attachment towards the money you just gave them – which arises out of self-cherishing. So in this case even though you are trying to help someone, your anger towards them is due to your self-cherishing.
