How long will your own world last?

Maharaj: Which world are you enquiring about?
Q: The world of my perceptions, of course.
M: The world you can perceive is a very small world indeed. And it is entirely private. Take it to be a dream and be done with it.
Q: How can I take it to be a dream? A dream does not last.
M: How long will your own world last?
Q: After all, my little world is but a part of the total.
M: Is not the idea of a total world a part of your personal world? The universe does not come to tell you that you are a part of it. It is you who have invented a totality to contain you as a part. In fact all you know is your own private world, however well you have furnished it with your imaginations and expectations.
Q: Surely, perception is not imagination!
M: What else? Perception is recognition, is it not? Something entirely unfamiliar can be sensed, but cannot be perceived. Perception involves memory.
Q: Granted, but memory does not make it illusion.
M: Perception, imagination, expectation, anticipation, illusion -- all are based on memory. There are hardly any border lines between them. They just merge into each other. All are responses of memory.
