Yesterday I was thinking about this:
There can be different planes, or levels of mind and you can freely choose to "tune into" them. If you tune into the higher frequencies, then your mind moves on those higher planes on its own
You can also choose to live in the lower planes, but then you will stay there. The choice on whether to go up or down in planes is entirely up to each person. Other people mostly keep you down in the lower planes and act like "ballast", unless it's a group of people purposely focused on doing exactly the opposite
