PAY ATTENTION KIDS! TNG SPOUTING WISDOM ALL UP IN HERE. I do take slight issue with How do you talk to yourself? That brain is YOURS don't let it say shitty things. I've introduced a new mantra "Start Again." If I find negativity in my head, I say "start again." It gives me permission to wipe the mental slate and start again.
You aren't "living with yourself," you ARE yourself.
only because of some stuff that crops up when I meditate. After sitting regularly for a while, you will notice that there's two you's up in your head. There's the stream of thoughts that pours out of your brain, like 'What was that noise? Did I pay my water bill? I wonder what I should make for dinner? This seat is uncomfortable.' and then there is the 'you' that watches that process happen. Your brain creates thoughts just like your pancreas create insulin, like your gallbladder creates bile. But there's definitely something else that sits in between the stream issuing from the brain and our actions.
Those are thoughts, they're not "you," just like your insulin is not "you." There is just one you.
