Is that your brain or whatever you want to call it, your mind, your perceptual field, adapts automatically to whatever is presented within it. In other words, any reference point you feed into it has the potential of becoming a fixed star within a constant universe.

The biggest danger of re-patterning yourself is that you inevitably pull out these fixed reference point anchors, which you imagined in previous states of selfhood to be Absolute Truths™. As you pull these out, demolishing them one by one, your experience of reality changes accordingly, as opposed to Reality Itself™.
