Actualize your individuation through the four alchemical stages of transmutation.
What is the Magnum Opus?
The Great Work (in Latin: Magnum Opus) refers, in the alchemical and Hermetic tradition, to the process of transmutation of the primal material (prima materia) into the philosopher’s stone. The philosopher stone is the most refined and valuable substance which through the alchemical process emerges from the crudest and most worthless. In traditional alchemy, this was the transmutation of lead into gold. Later, in the Gnostic tradition, this was interpreted not as the transmutation of metal, but of the soul or psyche of the alchemist himself. 
How does this translate into psychology?
Carl Gustav Jung (1875 – 1961), the founder of analytical psychology, usually referred to as “Jungian psychology”, saw in Gnostic alchemy a precedent to the process of individuation, as encountered in his own clinical practice. This was a breakthrough for Jung and offered a vast amount of data supporting his theory of the collective unconscious; more specifically, that psychic transformation follows an archetypal and universal process. This transformative process happens through the integration of the conscious and unconscious aspects of the subject’s psychology. Jung describes this process as having four stages: confession, elucidation, education and transformation. This is an analogue for the four stages of alchemical transmutation: Nigredo, Albedo, Citrinitas and Rubedo. 
Individuation as the goal of the Magnum Opus
Individuation, in Jungian psychology, is the process whereby an individual realizes a state of spiritual and psychological wholeness. Through this process, that, which was previously fragmented and broken, is restored and synthesized so that a whole and unique individual emerges; an individual who fully accepts, and is one with, him or herself; an individual who is fully authentic and embraces his or her destiny. It is a movement away from being a pawn in the hands of fate, to consciously collaborating in the realization of one’s unique destiny.
What the Centre for Applied Jungian Studies does
The Magnum Opus online programme in Applied Jungian Psychology is designed to take the student through these four stages of transmutation and transformation. The trajectory and goal of this process is clear, to produce the Philosopher’s Stone. In the terms of Jungian psychology this is individuation. To better describe this goal, we include two additional, essential elements in our stated objective of individuation: consciousness and meaning.
The four stages as four courses
The four stages of the Magnum Opus programme mirror the four stages of alchemical transmutation and of psychological transformation. They they are Nigredo, Albedo, Citrinitas and Rubedo. In psychological terms Jung described these as: Confession, Illumination, Education and Transformation. Each stage is twelve weeks in duration and focuses on the key Jungian psychodynamic concepts related to that stage. Although these stages are chronological in traditional alchemy, in line with Jung’s psychological model, the course design accommodates entry at any of the first three stages: Nigredo, Albedo or Citrinitas. Admission to Rubedo, however, the final stage, requires the completion of all three earlier stages.
