A "field" in the Bible usually represents the Lord's church, and more specifically the desire for good within the church. It's where good things start, take root, and grow. When you have a desire to be a good person and to do good things, the natural first questions are "What does that mean?", "What should I do?", "What can I do?". You look for ideas, concepts, direction. Once you figure out something you want to do or a change you want to make in yourself, you seek specific knowledge. If you want to volunteer at a food pantry, say, you'd need to know whom to call, when they need help, where to go, what to bring. Armed with that knowhow, you're ready to get to work. That process could be compared to food production. You start with a field -- which is that desire to be good. Then you plant seeds -- those ideas and concepts. Those seeds sprout into plants -- the specific facts and knowledge needed for the task (easily seen in the food pantry example, but also true with deeper tasks like "being more tolerant of my co-workers" or "taking more time for prayer," or "consciously being a more loving spouse"). Finally, those plants produce food -- the actual good thing that you go and do. The Writings also say that in a number of cases a "field" represents the doctrine, or teachings, of the church. This sounds markedly different. The desire for good is emotional, a drive, a wanting; doctrine is a set of ideas. But for a church to be true, its doctrine must be centered on a desire for good, and must lead people toward doing what is good. So sound doctrine is actually closely bound up with the desire for good.

7848. 'On the houses' means the desires composing a will that seeks what is good. 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.
