Until recently I thought of this as only a religious term. But, it’s not only that:

Merriam Webster:
Grace: disposition to or an act or instance of kindness, courtesy, or clemency

I’m thinking of this as how can we give ourselves grace. We tend to be so very hard on ourselves, more than we would be on anyone else. So I am trying to provide myself with grace. This is more than just kindness, because thinking ‘be kind to yourself’ hasn’t worked well. But ‘give yourself grace’, conjures up a whole world of kindness, gentleness, and forgiveness.
