Throughout the ages men have been intuitively aware of the existence of an inner centre. The Greeks called it man's inner daimon; in Egypt it was expressed by the concept of the Ba-soul; and the Romans worshiped it as the "genius" native to each individual. In more primitive societies it was often thought of as a protective spirit embodied within the animal or a fetish.
This inner centre is realized in exceptionally pure, unspoilt form by the Naskapi Indians, who still exist in the forests of the Labrador peninsula. These simple people are hunters who live in isolated family groups, so far from one another that they have not been able to evolve tribal customs or collective religious beliefs and ceremonies. In his lifelong solitude the Naskapi hunter has to rely on his own inner voices and unconscious revelations; he has no religious teachers who tell him what he should believe, no rituals, festivals, or customs to help him along. In his basic view of life, the soul of man is simply an "inner companion," whom he calls "my friend" or Mista'peo, meaning "Great Man." Mista-peo dwells in the heart and is immortal; in the moment of death, or shortly before, he leaves the individual, and later reincarnates himself in another being.
...I mention these very primitive people because they are uncontaminated by our civilized ideas and still have natural insight into the essence of what Jung calls the Self.
