If you have to do something you don't want to do, it is slavery. If you choose to do something you want to do, it is indulgence. If you choose to do something you don't want to do, it is sacrifice. If you have to do something you want to do, it is neurotic. Choose wisely.
The little ego wants its way ... but you aren't that ego, the ego is a function of your emotions, it isn't even cognitive. If you come from the POV of your higher self, not your lower self ... then you are only oppressed if you choose to be. One can choose to change one's heart, about not wanting to do something, or you can do it in spite of your heart's inclination. Conversion to a new POV, or do your duty. Choose wisely.
