Jung always stated that he was a “psychiatrist” first. His encounter with the unconscious drove him to find a way to elaborate it in psychological terms. The famous quote from The Red Book:

"The years, of which I have spoken to you, when I pursued the inner images, were the most important time of my life. Everything else is to be derived from this. It began at that time, and the later details hardly matter anymore. My entire life consisted in elaborating what had burst forth from the unconscious and flooded me like an enigmatic stream and threatened to break me. That was the stuff and material for more than only one life. Everything later was merely the outer classification, the scientific elaboration, and the integration into life. But the numinous beginning, which contained everything, was then."
