If, however, the passion can be removed, there’s no more “there” there.
One sutta illustrates this with a simile: the sun shining through the eastern wall of a house and landing on the western wall. If the western wall, the ground beneath it, and the waters beneath the ground were all removed, the sunlight wouldn’t land. In the same way, if passion for form, etc., could be removed, consciousness would have no “where” to land, and so would become unestablished. This doesn’t mean that consciousness would be annihilated, simply that — like the sunlight — it would now have no locality. With no locality, it would no longer be defined. This is why the consciousness of nirvana is said to be “without surface” (anidassanam), for it doesn’t land. ~ A Verb for Nirvana, by Thanissaro Bhikkhu
