Question

A swiss psychoanalyst who described religion as something that grew out of the individual's need to arrive at personal fulfillment, which he called individuation

Answer 1

The answer is "Carl Gustav Jung".

Carl Gustav Jung was a Swiss psychiatrist and psychoanalyst, and also known as the founder of analytical psychology. He is best known for his theories of the Collective Unconscious, including the idea of archetypes, and the utilization of synchronicity in psychotherapy. Archetypes, he recommended, were intrinsic inclinations that assume a job in affecting human conduct.  

Jung trusted that the human mind was made out of three segments: the self image, the individual oblivious, and the aggregate oblivious. As indicated by Jung, the ego represents the conscious personality while the individual oblivious contains recollections including those that have been stifled.
