Carl Jung: Each new case that requires thorough treatment is pioneer work
Consciousness, no matter how extensive it may be, must always remain the smaller circle within the greater circle of the unconscious, an island surrounded by the sea; and, like the sea itself, the unconscious yields an endless and self-replenishing abundance of living creatures, a wealth beyond our fathoming.
We may long have known the meaning, effects, and characteristics of unconscious contents without ever having fathomed their depths and potentialities, for they are capable of infinite variation and can never be depotentiated.
The only way to get at them in practice is to try to attain a conscious attitude which allows the unconscious to co-operate instead of being driven into opposition.
Even the most experienced psychotherapist will discover again and again that he is caught up in a bond, a combination resting on mutual unconsciousness.
And though he may believe himself to be in possession of all the necessary knowledge concerning the constellated archetypes, he will in the end come to realize that there are very many things indeed of which his academic knowledge never dreamed.
Each new case that requires thorough treatment is pioneer work, and every trace of routine then proves to be a blind alley.
Consequently the higher psychotherapy is a most exacting business and sometimes it sets tasks which challenge not only our understanding or our sympathy, but the whole man.
The doctor is inclined to demand this total effort from his patient, yet he must realize that this same demand only works if he is aware that it applies also to himself. ~Carl Jung, CW 16, Para 366-367
