“We are not our feelings. We are not our moods. We are not even our thoughts.” Stephen Covey from Seven Habits of Very Effective People. Our feelings and our moods are just energy-in-motion. E-Motion. As Buddha explained, they arise, then fall away.
Now, just take a deep breath if an unpleasant emotion, thought, or mood arises. Feel it fall away. It may take a moment or two. No rush. This practice keeps you aware of what is happening inside of you. Keep breathing.
For three days, watch, listen, feel how your emotions, moods, and thoughts arise and then fall away. Remember the breath and be amazed. You will realize that you are not your feelings, moods, or thoughts. They are transient. More on getting free next time.
