House
A "house" is essentially a container -- for a person, a family, several families or even a large group with shared interests (think of the term "houses of worship.") In the Bible, a "house" is also a container, but for spiritual things rather than natural things. In various uses a "house" can represent part of the mind, the whole mind, a whole person or even a church. The other nuance to the word "house" is that it is generally used in regards to our affections and desires rather than our thoughts and principles. This makes sense; we tend to engage our thoughts and rationality when we are out in the world doing our work, but when we are inside our houses we are driven most by love for our families and the desire to be good to those we love. So "house" tends to represent the things we want and care about -- which are ultimately the things that define us.

6483. From what has now been stated it may also be seen that what is overall is conditioned entirely by its specific aspects. The less precise these are, the more inferior also is the quality of the overall; but the more precise they are, the more superior therefore is the quality of the overall. For the specific aspects are what constitute the overall and enable it to be spoken of as the overall. From this one may recognize what the Divine overall is like - that it is composed of specific aspects of the most precise nature; for being Divine and infinite the quality of it is very much superior to all else.
