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.

5248. 'And changed his clothes' means the change made so far as coverings of the interior natural were concerned, by the putting on of what was rightly suited to this. This is clear from the meaning of 'changing as removing and casting aside, and from the meaning of 'clothes' as the coverings of the interior natural, dealt with below. The putting on of what was rightly suited, meant by 'new clothes', follows on from this. Frequent reference is made in the Word to clothes, by which are meant lower or outward things which, being such, serve to cover higher or inward ones. 'Clothes' consequently means the external part of man and therefore what is natural, since this covers the internal and the spiritual part of him. In particular 'clothes' means truths that are matters of faith since these cover forms of good that are embodiments of charity. This meaning of 'clothes' has its origin in the clothes that spirits and angels are seen to be wearing. Spirits are seen dressed in clothes that have no brightness, whereas angels are seen dressed in clothes full of brightness and so to speak made of brightness. For the actual brightness that surrounds them looks like a robe, much like the Lord's garments when He was transfigured, which were 'as the light', Matthew 17:2, and 'glistening white', Luke 9:29. From the clothes they wear one can also tell what kinds of spirits and angels they are so far as truths of faith are concerned since these are represented by their clothes, though only truths of faith such as exist within the natural. The truths of faith such as exist within the rational are revealed in the face and in the beauty it possesses. The brightness of their garments has its origin in the good of love and charity, for that good shines through and is the producer of the brightness. From all this one may see what is represented in the spiritual world by clothes and as a consequence what is meant in the spiritual sense by 'clothes'.

[2] But the clothes which Joseph changed - that is, cast aside - were those of the pit or prison-clothing, which mean the delusions and false ideas that are stirred up by evil genii and spirits in a state involving temptations. Consequently the expression 'he changed his clothes' means a casting aside and a change made in the coverings of the interior natural. And the clothes which he put on were ones such as were properly suitable, so that the putting on of what was rightly suited is meant. See what has been stated and shown already regarding clothes,
