Because every person lives in the world of their own creation, the social landscape built by the dreaming mind. In this world, they have their own self-image, and the images of other people. But these landscapes are vastly different from person to person, so the mismatch between how I see you and how you see yourself is the source of all conflict. For example, if I think of you as greedy, and you think you’re generous, you’re not gonna be happy with me. I will let you know what I think of you in all kinds of attacks and verbal cues, sometimes consciously, but predominantly unconsciously and completely unbeknownst to me. For that, you will probably think I’m arrogant, but I, of course, view myself as a humble person who is not as greedy as you are - otherwise why would I have a problem with your greed? Hahaha. Another mismatch, another conflict. So this constant play and mind-fuckery manifesting itself pretty much continuously in all forms of communication, whether verbal, written, or bodily is the source of all interpersonal conflict. I think I’m better than you in some ways, you think you’re better than me in some ways. And we’re constantly pointing that out, without noticing.

Break free from the cage of your mind and destroy your self-image, and all interpersonal conflict will cease.
