Imagine this: There's a piece of paper that is a different color on each side, yellow on one side and blue on the other. There's two people, one positioned on each side of the piece of paper so that they can only see one color. They're asked what color the paper is, and the following conversation ensues:
The first person says, "That's kind of a silly question to ask, the paper is obviously blue."
The other replies, "What? The paper is clearly yellow."
"Are you blind? It's blue, do you even know what blue is?"
"It's yellow dammit!"
They continue to argue, and eventually leave, both quite angrily. Based upon limited information, they made assumptions and each believed that their view was right. Each thought the other was a fool for not perceiving things their way.
Now, imagine the same scenario with two new people, who have the following conversation:
The first says, "I see a blue piece of paper."
The next replies, "Odd, I see a yellow piece of paper."
"That is odd, you wouldn't happen to be colorblind, would you?"
"Nope, I see just fine. Perhaps this is some sort of trick?"
"Yes, perhaps the paper is simply a different color on each side?"
In this scenario, neither person assumed they knew what the other person saw. They each communicated their perspective, and combined them together to realize the truth of the situation.
There is so much going on in every moment that being aware of it would completely blow your mind. You see only a tiny fraction of a tiny fraction of what is really occurring. It's extremely arrogant to believe that your unique perspective is the "right" way of seeing things.
