The medium perceives so clearly the reality of the surviving personality that the medium to some extent directly perceives that reality. You see the correlation here with what I told you in the past about experiencing concepts. That is one thing. To experience the reality of another does not necessarily mean that the medium negates her own personality—only that momentarily she allows it to perceive as directly as possible the experience of what it is to be the other. This involves a high degree of cooperation from the other person who does not exist in your physical terms, an opening of his reality to the medium rather than an invasion of the medium.

Therefore you accept them for they make sense to the physical mechanism. The inner self has the knowledge behind these physical perceptions. The brain is responsible for these physical symbols. The mind has no need of them, but passes the information to the brain, who then interprets it.
