At first the operator may succeed by very imperfectly stimulating the brain of the sensitive and causing the cerebration and expression of his thoughts. The utterances may bear but a slight resemblance to what the spirit intended to express. The vocabulary is that of the medium, and the form in which the speech is cast of necessity partakes of the mold familiar to the sensitive--but, by continued close association and frequent control of the medium, the operator gains experience which enables him to exert a more decided influence; and the sensitive, becoming attuned, responds to and expresses the thoughts of the spirit with greater clearness and precision. Just as those who dwell together unconsciously approach nearer to each other and acquire a similarity in their mode of thought and of expressing their ideas (the more dominant personality impressing itself upon the less positive), so the medium imperceptibly, and very often unconsciously, acquires facility and proficiency in thought and elocutionary expression as the result of the co-operation between himself and his spirit guide.
