A Sunao Mind

What is a "sunao" (untrapped or open) mind? It is not just a mind that is simply obedient or that does not oppose other people. I believe that the true meaning of sunao has strong and posios1tive ti connotat10ns.
My point is that a sunao mind may be described as one that is unselfish, transparent, unattached to any one thing and able to see everything just as it is. I believe that the ability to grasp the true nature of things is born from such minds. I believe that a sunao mind is able to see truth; such a mind can probe the truth of a situation and adapt accordingly.
