It turned out that spiritual people are not that perfect after all. My almost-husband pointed out that I held resentment for my sister some time back in my venting moments. Of course, I didn't see it at first; after all, I am a good person and speak of tolerance, letting go, and all kinds of forgiveness. But it was true.
Gratitude helps people be more of themselves. No one can feel gratitude and be angry, mad or sad at the same time. It is impossible!
