Here's an example of one of Jung's brilliant concepts that can be used with Tarot. Note: others use active imagination/visualization, but his is used within and as a part of his whole understanding of the psyche:
Active Imagination— a creative technique using mental imagery for working with the unconscious and getting in touch with archetypes [read: Tarot Majors].
“In Active Imagination the important thing is to begin with a particular image...Consider the image and carefully observe how it begins to unfold or to change. Avoid all attempts to bring it into a particular form; simply do nothing other than observe which changes take place spontaneously. Every psychic image that you observe in this fashion will sooner or later change shapes on the basis of spontaneous association, which leads to a subtle change of the image. Impatient hopping around from one theme to another is to be carefully avoided. Stick with the image that you have chosen, and wait until it changes of its own accord. You must carefully observe all of these changes and then you yourself must enter into the image. If you meet a figure that speaks, say what you have to say as well, and listen to what he or she says. In this fashion, you not only analyze your own unconscious, you can also allow the unconscious to analyze you. Thus you gradually achieve a consensus between consciousness and unconscious, without which there is no individuation.” Jung, C.G. Briefe Bd. 2, S. 76.
“The best way of dealing with the unconscious is the creative way. Create for instance a fantasy. Work it out with all the means at your disposal. Work it out as if you were it or in it, as you would work out a real situation in life which you cannot escape. All the difficulties you overcome in such a fantasy are symbolic expressions of psychological difficulties in yourself, and inasmuch as you overcome them in your imagination you also overcome them in your psyche.” —C.G. Jung, 25 November 1932.
Marie-Louise von Franz called it a "creative act of liberation."
