A mind that agrees with truth but never practices it has built its peace on nothing, on the shifting ground of appearances where the ego rules. To hear and not do is to leave the old foundation in place while admiring a better one, and a peace with no root in love has nothing to hold it when fear arrives.
So the first grievance that beats against such a mind brings the whole structure down, and the collapse feels total because there was never anything solid beneath it. The ruin is not a punishment; it is only the discovery that a peace founded on the world falls the moment the world turns, and love was the ground it declined to stand upon.
House: the mind's sense of itself, the peace it built on words it would not live.
Earth: the shifting ground of appearances, the ego's foundation that cannot hold a mind when fear rises.
Stream: the current of attack thoughts beating against the mind, finding nothing rooted to withstand it.
