Once upon a time, a rat was about to have a field trip, so he consulted his buddy Meow : What Has Serendipity Ever Done For Us?", the Meow rolled her eyes, answered: "I heard about a land of Unusual Perspectives where the wizards hid their treasure in boxes!".
So the rat travelled to a high land which piled with a lot of stuff, and there was a sweetish smell, vaguely reminiscent of the kitchen of the rat colony.
"Hurrah!", rat was in rapture.
In a distance, "Hurrah!", a hungry serpent gave a venomous bite of the air, and thought: "time for my good luck in making unexpected discoveries!".
So the serpent hid himself in a box, for making sure the rat will cave in, he painted the box with words "Treasure in Box!"...
Ok, similar considerations, apply to the closely related concept of "consciousness"; that too, is a mystery no more. We already knew what will happen.
So the rat get "paradigm-shifted" and "existentially-transcended" into a part of the serpent-hood. The rat has now capable to look through the eyes of the serpent, and it gave him a Unusual Perspectives with a racking shock: "The beauty of the scenery surpassed my expectation!", said the shape-shift, "I am not standing at a treasure-land, it is a wasteland of trash!"
Do cave in then
