Only when I think I have something can I fear losing it. Only when I think I know something can I doubt knowing it. For having and not having are absolutes, as is knowing and not knowing. Any feeling of need to think on it -- is its own answer. Don't try to know what you don't; don't extend the concept of possession. In your own hands, right now, is the only fact: and what your heart is sure of, right now is the only knowledge.
