Emotion is much more than fear. On a broad scale, emotion goes from apathy to serenity of beingness. There are many emotions in between. Sympathy, rage, covert hostility, boredom, interest, enthusiasm, exhilaration and more. There are negative emotions and there are positive emotions.
Feelings can include emotions, but they include much more. Things like, attachments to your possessions, the sense of self-righteousness with ego, the frustration of being stuck in traffic, and more. These feelings are not emotions, but they can evoke emotions.
Most people wait for something to happen in order to feel an emotion, but ultimately, they are responsible for every emotion they feel. They create their emotions. All too frequently, the emotions they create are merely reactions to stimuli, but it doesn't have to be this way.
One time, when my life was going down the toilet, I went from feeling severe depression (apathy and grief) to exhilaration -- all by creating a new emotion by decision and responsibility.
My greatest bliss occurred moments after severe frustration that had blossomed into rage. When I took 100% responsibility for the assaults of others on my person, forgiving them completely, I felt nothing but love and utter humility. Then miracles happened, and I felt the love of God.
