In psychology, sublimation is a coping mechanism. It has its roots in the Nietzschean & psychoanalytical approach, and is often also referred to as a type of defense mechanism.
Sublimation is the refocusing of psychic energy (which Sigmund Freud believed was limited) away from negative outlets, toward positive, or the rechannelling of drives which cannot find an outlet. For example, a student worrying over a major exam might rechannel that energy into studying, and a rageful person who is accustomed to lashing out might rechannel their passion through introspection and organization.
Or, in this case, one could refocus all the psychic energy that results from the desire to explore onto a piece of paper, canvas, stone and create some art. Perhaps more Jungian than Freudian.
