Eh, I'm going to disagree with that. We are not "all one and nothing exists". We humans label and define things because things are different and serve different purposes. We don't plunge the toilet with a tooth brush, now do we? Labels and definitions exist for a reason. There is nothing wrong with categorizing a,b, c, etc etc or having rules/principles. Even animals do this.

The problem comes into play when we cannot have a god damn respectful discussion with one another for whatever reason or entertain a thought for whatever reason. That would be more about the ego and dare I say, a spiritual discussion of Natural Truth/Law.

Which takes us all the way back to the big bang or a mysterious non-existent ancient monkey ancestor. We never get to it. *Paraphrased from Alan Watts. *
