3196. 'And Isaac came out to meditate in the field' means a state of the Rational immersed in good. This is clear from the representation of 'Isaac' as the Divine Rational, often dealt with already, and from the meaning of 'meditating in the field' as its state when immersed in good. For 'meditating' is a state of the rational when this controls the mind. 'A field' however is doctrine and the things that constitute doctrine, 368, and so the things that constitute the Church as regards good, 2971. Consequently the expression of old 'meditating in the field' stands for thought immersed in good, which is the condition of an unmarried man (homo) with thoughts of a wife.

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.
