I had lunch at an outdoor table today, and there was a homeless (?) man and his dog not too far away. He talked to himself about whatever was happening, including cars running their engines while being parked.
I realized that his thoughts were the same thoughts as I have. Every single one of them were familiar to me.
And I also talk to myself. I talk with myself through my internal monologues and dialogues about whatever is happening. And if I am honest, I often talk to myself and for my own benefit even when somebody is there listening and responding.
Again, when I look I find that he is me, in a very real sense.
This is of course at the relative level, where there is an apparent separation. Even as there is a belief in I placed on this human self, he is me.
