yes, maybe it's my mistake!
i have read about the practice of "black dot" when a person just sits and looks in the wall where there is a black dot (in imagination, not a real one), and he is looking and looking...thinking only about tis very dot.
Stopping of inner dialog - this practice is called in such a way, we need to stop our thoughts and learn to think only about the dot
it's veeeeery hard but many people say when you are able to do it - you're almost on the top
but I like your theory more) in the beginning it's really easier
