Most people want to understand and be understood even on a most basic level. Yet a wise one knows that this does not mean that you have to know everything. The sage also is unconcerned whether he is understood or not. He merely seeks to follow his way as water seeks its level. Wisdom is the quiet and deep water. It is the farthest star in the sky that often goes unnoticed. If you know everything about something, the exotic mystery of the unknown is lost. The sage makes no effort to know everything and thus knows the most.
