One of the main tools for entering into the vivid immediacy of quiet mind is “not knowing.” Ordinarily, our minds are filled with all kinds of opinions about who we are, what we are doing, what is important and not important, what is right and wrong, and how things ought to turn out.
Because our mind is full of opinions and old thoughts, it has no internal space for a fresh impression of the real world around us. We learn nothing new. This also prevents us from really seeing other people – especially the people we love. We imagine that we really know people or even what they are thinking. Many of us know from experience, though, that to experience freshly someone we know can instantly transform our state and theirs. In some cases, this can save a relationship.
Not knowing involves suspending our opinions and letting our curiosity within the realm of quiet mind take the lead.
