Banzie believe that eboga enables a man or woman to return to infancy and to birth - to the life in the womb. All the sins of life cause people to forget their origins in the land of the dead beyond the sea. This is the land from which all spirits come to be incarnated and to which they return. The two sins of early life which cause forgetfulness of this ancestral land are sins of violating one's mother's private parts. One sins in being born and one sins in eating at one's mother's breast. If this propensity to violate another's being is allowed to continue into adulthood it eventuates in witchcraft, the consuming of another's substance. But eboga by returning initiates to the uterine condition, a condition in any case very close to life in the land of the dead, restores them to their own integrity - their pristine conditions. Eboga miraculously returns them to the same original and final place. It is another form of the "saving circularity."
Bwiti seeks in "original and final" place - a spiritual point, as it were, from which birth and death in all their contrarieties and complexities can be uniquely contemplated. Ultimate place is obtained in the visions when the initiate arrives at the center of the rainbow. This is the spot from which he can see the entire circle of the rainbow as well as the entire circle of the earth. Even though the visionary may not have seen any spirits or gods in his journey this is a sign of the success of his vision.
When heavy doses of eboga are being taken, some chapels modify the ritual. Sometimes the initiate is surrounded by a vertiginous circle of members dancing, singing, and shouting. Drums may be beaten incessantly even in the initiate's ear.
Most chapels provide very careful supervision of the initiate. The eboga parentage, the mother of eboga and the father of eboga, watch the initiate and encourage the initiate against anxiety. Initiates often mumble or even shout under high dosage. Eboga mother and father listen carefully to see if they can make out any message from eboga. Some chapels don’t provide such careful construction of set and situation, and these tend to be the houses afflicted with bad visions.
