Consciousness is affected by experience but not harmed. It is the nature of aware consciousness to be affected by everything it experiences. Every color and sound, every event and experience, and every passing thought or feeling affects your consciousness. That is why we call it consciousness. A rock isn’t as affected by these things, so we consider a rock less conscious than a person.
And yet, consciousness is not harmed by anything. That is its nature, that it can’t be harmed. The form of anything can be harmed or permanently changed. Your body can be harmed, but the consciousness that contains your body cannot be harmed. This is good news. It’s like a “Get out of Jail” card in Monopoly. No matter what happens, you, as consciousness, are completely unharmed. What a relief! There is nothing that can harm you. No one and nothing has ever harmed you.
This is not to say that consciousness isn’t affected deeply by both the good and bad things that happen to us. Every hurtful and unkind act leaves an impression in the consciousness of those involved. It’s just that the impression doesn’t permanently limit or damage the awareness of those involved. If something permanently affects us, it could be said to have harmed us. But if the effect is temporary, then what is the ultimate harm? Everything that profoundly affects our awareness, from the beautiful to the tragic, eventually passes. It is the miracle of our consciousness that it can heal from any wound, even if our body cannot.
