When you are given answer to your question, you have the stereotype response: This is not answer!
I say that because nothing you wrote is in any way close to an actual answer. I asked a specific question about how turning your brain off works and you go on about water pipes. You clearly cannot answer anything about this. You don't actually know anything about this process. That's fine, but you don't get to pretend you do.
Let me enjoy my meditation and benefit from it without any measure!
You are free to not post and go meditate instead of making claims here and get asked questions. Absolutely no one is stopping nor did anyone force you to pretend you knew something about the subject.
