I look at the sky and I see it as Azure, and so do you. But to me as well as to you, the color azure is in the head, being created by the brain based on the data from the external reality.
In the objective external reality, there is no azure; there is electromagnetic radiation of a certain wavelength. Similarly, I can not deny that there is no azure, although I perceive it (or I represent it) so I can not deny it, and I can’t believe there is no “I” when I experience the feeling of self entirely at this moment. The ego is a trick, a scam of the brain. It does not have a real, objective existence. Still, we strongly believe in the reality of this scammer. That’s why we hurt or enjoy when someone, especially someone we love, labels us.
But now think a little: can azure be a smarter or stupider color than yellow? Do you believe that electromagnetic radiation of different wavelengths is hurt or excited when you call it stupid or intelligent?
