Water in the Bible represents true ideas about natural, external things – day-to-day life and physical existence. The sea represents the whole collection we have of these natural truths (to use a common term from the Writings). Those representations – like all other representations in the Bible – can be negative as well as positive; the water in the sea can also represent false thinking and twisted logic. This is especially true when a storm stirs up the sea and causes waves; the waves represent arguments which come from false and twisted thinking and which attack our belief in what's true. In most cases this comes in the form of temptation, when false thinking attempts to link up with our evil desires and convince us that it's OK – and even good – to go ahead and do what we want.

3889. To enable me to know not only that there is a correspondence of celestial things, which are those of love, with the motions of the heart, and of spiritual things, which are those of faith derived from love, with the motions of the lungs, but also the nature of this correspondence, I was allowed to spend a significant amount of time with angels who were to demonstrate this to me visually. By means of wonderful circular movements, impossible to describe, they formed a resemblance of the heart and a resemblance of the lungs, including all the intricate interior and exterior parts which the heart and lungs possess. They traced the spontaneous flow of heaven, for heaven strives to exhibit that form from the influx into itself of love from the Lord. In this manner each individual part of the heart was exhibited, and after that the union of the heart and the lungs, which union they also represented by means of the marriage of good and truth. From this also it was evident that the heart corresponds to the celestial element of good and the lungs to the spiritual element of truth, and that the material form in which the two exist joined together is the heart and lungs. I was also told that the same applies throughout the whole body, that is, to things of the heart and those of the lungs within all the individual members, organs, and viscera of the body. For where the two are not acting together but each one by turns separately, no motion of life belonging in any way in the will can exist there nor any feeling of life beginning in any way in the understanding there.
