'Six at the Top makes his house large' through 'he is not seen.' The Correct Meaning states: A house is that which provides shelter, shade, and concealment.
Six at the Top, being yin in a yin position, at the extreme and residing outside, does not tread upon an official post; this is deeply hiding oneself in obscurity, cutting off traces and concealing oneself deeply. This matter is identical to making one's house thick and large.
Having enlarged his house, he also veils and screens his home; with a thick house and a darkened home, the obstruction is extreme. Though one peeps through his door, it is quiet and desolate with no one there; he abandons his dwelling place and hides himself deeply.
Living in an age of abundance and greatness, hiding does not constitute worthiness.
When the order of governance is not yet complete, hiding is still permissible; but when three years have passed and the Dao of abundance is already completed, yet he still does not appear, this is why it is unfortunate.
Hence it is said: 'He makes his house large, veils his home, peeps through his door, and it is silent with no one there. For three years he is not seen: misfortune.'
