Start watching your thoughts and feelings as well as the outside world and you will discover something beyond blankness.
Stop for a moment and look at the table next to you, or a nearby ornament. Then quickly look away and look back at it. Can you see all the finer details now? The texture, the way light reflects of it, the curvatures, the variation of colour.
Generally when we look at the world we mostly just gloss over, not really seeing anything. When we start really seeing things in their glorious detail we find the world is not as dull as we once thought. When we didn't pay attention.
The first point I made is more important.
