how can 4th/5th/6th density negative entities exist without the veil?

I think the TL;DR of Cyclops' quotes could be boiled down to: "Negative entities -especially 5D/6D- already see themselves AS Creator and, as such, attempt to reform the world according to their desires because they perceive no powers higher than themselves." Which would also be my short answer to the question.

I'd say you can even see this reflected in the behavior of negatively-polarized humans on Earth. They tend to universally reject the idea that they could ever be wrong about anything, or that anyone has any ability to gainsay them. And perceiving conflict with their own desires, they will often go to incredible lengths to remove that source of conflict, seeing it as an exercise of Willpower. Any conflict resolved in their favor, no matter how extreme the methods employed, is further proof (to them) of their inherent superiority.
