Summary: Thoughtlessness, no-mind are terms which are being used very often these days. Sadhguru says - "it took millions of years of evolution to get to a mind of this kind of capability". So, why would you want to stop it? It's because this mind is producing unpleasantness, that's why you want to stop it - if it was producing pleasantness then you wouldn't want it to stop. What is important is to bring a little space between the you and your mind - once that happens then whatever is happening in your mind will not bother you.
