The types of societies which exert strong pressure for compliance are also those where we expect to find possession trance. the types of societies which exert strong pressure towards assertion are those for which we expect to find nontrance possession beliefs. the personalities and value systems developed in a society may be expected to be consistent with the conditions of livelihood and social organization which people face. And these in turn are reflected in their ideas concerning spirits and powers which constitute their religious beliefs. In societies in which one succeeds by being obedient, responsible, and nurturant, in short by being compliant, we may expect that such behaviour appropriate towards elders and those in power will also be appropriate toward powerful spirit beings. the individual enhances his power and his status by total abdication and self-effacement before the spirits. Hi abandons his body to them as their mount; his spirit vacates its place before them. he can achieve dominance and assertion only indirectly, through the unconscious pretense of obedience and submission.
On the other hand, the shaman who acquires power, and the witch as well, do not impersonate spirits, do not abdicate their own identity; even the patient who is diminished in some sense by spirit-intrusion illness remains himself. Those who through some form of possession acquire powers for good or for evil have these powers supplement their own; their selves are strengthened rather then displaced. A shaman,s chances for achievement are enhanced by the acquisition of spirit power. His relation with the spirit is not dependent on the group; rather, he has most likely obtained it on his own, in his own dealings with the spirit. Nontrance possession represents an alteration of the individual's capacities, not an alteration of his consciousness. In societies which socialize for assertion, such an alteration of capacities results from the interaction of dependent, self-reliant human beings with spirits or powers of limited capacities.
