In this letter Dick quotes a passage by John Calvin written in the 1500s about how human beings have supernatural abilities that will be restored by Christ. Again he relates to Claudia his experience of seeing Rome during the event that happened to him in March. 

In a postscript he pitches an idea of time in which time itself enters a person all at once as energy and we retain this in our heads as a potential which is slowly revealed. He uses this theory to explain déjà vu as we are glimpsing in advance what is already in our mind. 

The Immanent Mind which has been slumbering for two thousand years is now waking up.
