3096. 'And ran again to the well' means a lower affection for truth. This is clear from the meaning of 'a well' as truth, dealt with in 2702, but truth that is lower. And as the subject here is the introduction of truth, a lower affection for truth is meant, as stated just above in 3094. For the difference in meaning in the internal sense between 'a spring' and 'a well' see the paragraph just referred to, where it is explained that the expression 'a spring' is used in reference to purer and higher truth, but 'a well' in reference to truth that is not so pure and is lower, as in the present chapter also where 'a spring' is used at one point, 'a well' at another. Natural truth is a lower variety of truth, and the affection for natural truth a lower kind of affection for truth. This truth enables general facts to receive light most nearly, and that enlightenment penetrates further and affects more deeply, see 3094.

The heart means love. A good heart means love to the Lord and to the neighbor, while a hard or stony heart means the love of self or the world -- riches and things. When the psalmist asks the Lord to search his heart, he wants the Lord to see what it is that he loves. And we are what we love. What we eat may form our earthly body, but it's only temporary, what we love forms our spiritual body, beautiful or ugly as we have chosen. It's interesting to note that the first multi-cellular motion of our embryo is the pulsating that starts in a twist of blood vessel that is to become our heart, and the last motion of our natural body is our heartbeat. It is there for all of our natural life. And of course there is a beating heart in our spiritual bodies when we come to put them on.
