Since early childhood I believed that I am one with all other beings. I believed I live every day in everyone's mind. As if I'm playing chess with myself without having access to my opponent's memory.
I didn't think anyone could really understand any of that so I never shared these thoughts with anyone. At some point I just forgot about this.
But now here I am, once again exposed to this doctrine that is simultaneously so new and yet so familiar. Closed individualism only made sense when I wasn't thinking about it. Like what if you divide someone's brain? Where would "you" end up? Both! Isn't it plausible?
