"Turn on the faucet. Wash yourself with the emotion. It won’t hurt you. It will only help. If you let the fear inside, if you pull it on like a familiar shirt, then you can say to yourself, 'All right, it’s just fear, I don’t have to let it control me. I see it for what it is.'"

- Mitch Albom (Albom 31)

"Same for loneliness: you let go, let the tears flow, feel it completely—but eventually be
able to say, 'All right, that was my moment with loneliness. I’m not afraid of feeling
lonely, but now I’m going to put that loneliness aside and know that there are other
emotions in the world, and I’m going to experience them as well.'"

- Mitch (31)

"But by throwing yourself into these emotions, by allowing yourself to dive in, all the way, over your head even, you experience them fully and completely. You know what
pain is. You know what love is. You know what grief is. And only then can you say, 'All
right. I have experienced that emotion. I recognize that emotion. Now I need to detach
from that emotion for a moment.'"

- Morrie (30)

"If you hold back on the emotions—if you
don’t allow yourself to go all the way through them—you can never get to being
detached, you’re too busy being afraid. You’re afraid of the pain, you’re afraid of the
grief. You’re afraid of the vulnerability that loving entails."

- Morrie (30)

Overcoming the fear of experiencing emotion will eliminate the fear altogether.

In Chapter 15: The Sixth Tuesday We Talk About Emotions, the pair discusses a strategy for approaching emotions. As shown in the above excerpts, they encourage a full experience and therefore a deep understanding of what an emotion feels like. Afterwards, you'll be able to set the feeling aside and continue to learn about the rest. The third excerpt states that without such investigation, these emotions will never be conquered; the fear of a painful experience will prevent you from moving past the emotion. The experience will remain unknown and the fear will persist until the feeling is processed and no longer recognized as a threat. 

'Nightline'

Morrie uses the fear of death as an example of an emotion that should be explored rather than avoided.
