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.

1295. That 'one man said to the next' means that this was started, that is, men started it, follows from the train of thought. This verse is dealing with the third state of the Church when falsities began to reign, in particular the falsities that arise from evil desires. There are two sources of falsities, the first being ignorance of the truth, the second evil desires. Falsity that arises from ignorance of the truth is not so harmful as falsity arising from evil desires, for the falsity of ignorance is the outcome either of having been so taught since early childhood, or of having been so preoccupied with various pursuits that one has never looked into whether something is true, or of not having been competent enough to judge what is true and what is false. Falsities that are the product of such ignorance do little harm provided that the person has not confirmed himself much in them, and so has not, on the instigation of some evil desire or other, persuaded himself to the point of defending those falsities. If he has he so intensifies the cloud of ignorance and converts it into darkness that he is incapable of seeing the truth.

[2] But falsity from evil desires comes into being when the origin of falsity is evil desire, that is, self-love and love of the world, as when somebody takes some point of doctrine, preaches it to captivate and take control of people's minds, and explains or twists that point of doctrine to his own advantage, and confirms it both by reasonings based on facts, and from the literal sense of the Word. The worship that results from this is unholy, however holy it may appear outwardly. For inwardly it is not worship of the Lord but worship of self. Nor does such a person acknowledge any truth, except insofar as he can explain it to his own advantage. Such worship is what is meant by 'Babel'. But the situation is different with people who, though born and brought up in such worship, do not know that it is falsity, and lead charitable lives. Their ignorance has innocence within it, and their worship has the good flowing from charity within it. The unholiness of worship is attributable not so much to the actual worship as to the nature of the worshipper.
