If joy is your nature, and your heart is heavy, then you can know that you are away from your nature. It is unnatural for you to be unhappy and anxious. That is why it is so uncomfortable for you. If anguish were a natural thing, it would not be so disturbing.

You can bless even your anguish, however. It is signaling you to return to your nature of love. It is yourself you are not loving. That must be the case or you would not punish yourself so. Perhaps you consider yourself unworthy of joy. Perhaps you consider yourself worthy of woe.
