It is a law in the universe that a wave of spiritual awakening is always followed by a period of doubting materialism, each phase is necessary in order that the spirit may receive equal development of heart and intellect without being carried too far in either direction.

Doubting what you see is a very odd experience. And doubting what you remember is a little less odd than doubting what you see. But its also a pretty odd experience, because some memories come with a very compelling sense of truth about them, and that happens to be the case even for memories that are not true.
