3500. 'And go out to the field' means where a good ground exists. This is clear from the meaning of 'the field' as the good that constitutes the Church and also the good taught by doctrine, dealt with in 2971, 3196, 3310, 3317 - thus a ground that is good.

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.
