What some examples of catharsis in Toni Morrison's novel Beloved?Catharsis can be defined as the purging of emotions.

I think that you could make a case for catharsis amongst
several characters.  In my mind, Sethe undergoes the greatest amount of catharsis.  Her
narrative in the work is one entirely predicated upon evolution and change.  If we take
the "purging of emotions" idea, then the appearance of Beloved, as a spirit, is what
triggers Sethe to "come clean" about her own experiences and purge the past into the
present.  It is through this acknowledgement and acceptance that her perception moves
from black and white and into color.  Sethe is able to fully understand her role as a
former slave, as a woman, and as a woman of color in a more clear light as a result of
her being able to tell the story of what happened to her and her child.  As Deborah
Horvitz noted:

As the embodiment of
Sethe's memories,the ghost Beloved enabled her to remember and tell the story of her
past, and in so doing shows that between women words used to make and share a story have
the power to heal.

Such a reality
represents the essence of catharsis and character evolution throughout the course of the
narrative.
