Very good post. From what I have experience in non-attachment, fits what you are saying. I do not know of any one method/path that fits all individuals as to how this state can be achieved or maintained. Letting go and not allowing for attachment to anything, not having feelings for anything beyond the moment. Being empty when in active, and only addressing actions in the moment, letting go once the moment has passed, never allowing one to become overwhelmed by emotion felt toward the event.
