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.

But because this intelligence is today called faith, and this love, charity, it is faith springing from charity, or rather, it is the truth of faith springing from the goodness of charity, symbolized here by the star.

A star in the singular has a similar symbolic meaning in Revelation 2:28; 22:16. For stars in the plural symbolize concepts of goodness and truth (no. 51), and these are the means to intelligence.

That it is Divine truth examining and exposing is apparent from what follows.
