This is starting to get ridiculous, cluttering your mind with phony Feng Shui thoughts when the idea is to Free Yourself from Physical, Mental, Emotional, and Spiritual Clutter.
It is one thing to worry about where you will place your stairway. Worrying about quick references to exotic systems is another thing to free yourself from thinking.
Clutter is just another way of saying free association. Clutter can also be called treasure.
This book could be considered clutter. I would maybe toss it if not for the other 10,000+ books in my library. As for "just in case," if you get rid of it, you will want to replace it just in case. For memory's sake, wait until you retire before making radical disposal of irreplaceable items.
I am sure this is meant to be a sort of self-help. However, it does just the opposite. This is just a fad that you may not recover from.
