"Often it may simply sound like a figure of speech when I talk about probabilities. In many ways it may indeed appear to be almost outrageous to consider the possibility that "there is more than one earth" or that there are many earths, each similar enough to be recognizable, yet each different in the most vital respects.
This particular house exists. Yet you may open the door on any given day to a probable world from your immediate standpoint, and never know the difference. This happens all the time, and I mean all the time.
You move through probabilities without knowing it. The transitions are literally invisible to you, though they may appear as trace elements in your dreams. As a diamond has many facets, so does your reality in that regard."
