Every process that goes too far immediately and inevitably calls forth compensations, and without these there would be neither a normal metabolism nor a normal psyche. In this sense we can take the theory of compensation as a basic law of psychic behaviour.
Jung formally elevates compensation from a clinical observation to a foundational law of psychic self-regulation, grounding it in an analogy with biological homeostasis.
