This is clear from the meaning of 'house' as a person, dealt with in 3128, and as the human mind, 3538, 4973, 5023, 7353, consequently that which composes the will, at this point that which composes a will seeking what is good. The reason why 'house' also means the will is that a person is meant by it, and a person is a person primarily by virtue of what he wills. Furthermore, whether you say a person or his mind it amounts to the same thing. For a person is not a person by virtue of his physical body but by virtue of his mind; and what his mind is like - that is, what his understanding and will are like, primarily what his will is like - determine what kind of person he is.
