Creativity and Emotion

Is emotional intensity a precursor to creative intensity? One would say, what a redundant question, the two are co-dependent. Creativity is an uncanny blend of rationality, emotion and a strong individual desire--when released to the external environment, it triggers a complex reaction in the audience that even they cannot understand completely. What does this entail for the artist, the creator who puts himself through storms, deserts, deep blue oceans and bone-crackling cold? An original creation, they say, is born from the depths of the soul where that emotion auguring the creation is experienced with all its richness, from different angles.
