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.

6206. To take the subject further, it should be recognized that all evil flows in from hell and all good from the Lord by way of heaven. The reason however why evil becomes a person's own is that he believes and convinces himself that he thinks and practises it all by himself. In this way he makes it his own. But if he believed what is really so, it would not be evil but good from the Lord that became his own. For if he believed what is really so he would think, the instant evil flowed in, that it came from the evil spirits present with him; and since that was what he thought the angels could ward that evil off and repel it. For influx from angels takes place into what a person knows and believes, not what he does not know or believe; there is nowhere else for it to become firmly established than in something the person knows or believes.

[2] When a person in that way makes some evil his own he acquires the sphere that is a product of that evil. This sphere is what the spirits from hell who have a sphere of like evil around them associate themselves with, for like is linked to like. The spiritual sphere existing with man or spirit is an emanation from the life which belongs to his loves, from which his character is recognized from afar. Their spheres are what determine the ways in which all are joined to one another in the next life, and the ways in which communities are joined too. They also determine the separations that take place, for contrary spheres conflict with and repel one another. Consequently the spheres produced by the loves of what is evil are all in hell, while the spheres produced by the loves of what is good are all in heaven, that is, those dwelling in such spheres are there.
