Summarize one theory of Carl Jung. Please use at least 3 references. Also, please discuss the positive applications of the theory, and discuss the components of this theory that might make this theory challenging to apply. Discuss two ways in which this theory can be applied in a counseling setting. Include a description of how this theory can embrace multiculturalism and support culturally competent counseling practice.

One of Jung's theories is that of archetypes. Jung understood archetypes as manifestations of a universal collective unconscious. These could be seen across societies and were deeply embedded in the unconscious in a holistic manner, manifesting in art and life across cultural contexts.
Jung essentially rejected the idea that the mind was a blank slate, and archetypes were clear evidence of this fact. They were examples of imagery and ideas which welled up from the unconscious and represented deeply buried primal urges and impulses. They were best understood intuitively rather than rationally.
Jung saw these archetypes as being expressed in various ways, and he thought they captured various themes. There were archetypal phases of life (birth, death, and so on) and archetypal figures. One archetypal figure is the "hero." The mythologist Joseph Campbell expands on this concept in his book The Hero With a Thousand Faces, suggesting that the archetype of the hero is seen in myth and storytelling across cultural contexts. This is certainly one way that Jung's theory of archetypes could be seen as embracing multiculturalism. Other archetypes include archetypal events ("the deluge", "the apocalypse", and so on).
In therapeutic terms, the archetypes can be viewed as models or templates for "personality types," which engender certain behaviors. One can see how aspects of this view can have therapeutic possibilities while also realizing that their broad and perhaps oversimplified nature makes it hard to make them fit an individual's specific life experiences.
Archetypes can also be seen as providing a guide for the various stages of life, as human development and growth throughout life follows a kind of deeply ingrained archetypal form. Again, this can be seen to have therapeutic possibilities while at the same time being limited by the tendency to overgeneralize.
Archetypes have been challenged, criticized, and misinterpreted, but they still remain one of Jung's most powerfully influential and lasting concepts.
