“one sees what one wishes…”
I don’t think so.
What one wishes to see is controlled by someone who affected your free will and mental clarity negatively.
“The idea of the reflective nature of the Universe includes ideas that we are the causation of our own being.”
That is true though. So true, in fact, just today one of my clients discovered that, he was cause and effect of his own being. Pretty much what you just said. Also his words show that he discovered the original meaning of the word 'karma' as evidenced by his use of the words "cause and effect," Now, that is neat don't you think. By the way, this person is hardly familiar with Oriental concepts. He was absolutely delighted... Then he made another discovery, "I will take credit for anything real, truthful and energetic, as it is pure energy from the core of my being! But anything negative...? I may have bought it previously, and as such was led to believe that I owned it. But now I know that I bought it under duress...from an outside source. Negativity does not come from the core of my being, I know that now. Negativity does not even have substance. Yes there may be resistance to the force of my being, but that is only illusive resistance, intimidation brought about by fear. It may slow me down somewhat, my divine energy. But that resistance is not mine nor caused by me. After all we do not operate in a vacuum."
