In the Christmas story, the wise men bring gifts to the Lord: gold, frankincense and myrrh.

The gold is listed first, because it is the inmost - signifying good, e.g. the good that we do when we love the Lord and the neighbor.

The frankincense is next. It signifies rational truth, which is the set of true ideas that we know, not about external things like cars or cooking, but about what is really good, and what is really true.

These rational truths are built on earlier knowledges that we learn, before we have really made them our own. Those early knowledges about spiritual things - often learned in childhood - are represented by the myrrh.

In a way, these gifts are really a reciprocation. We can't actually give them to the Lord until the Lord has given them to us. We necessarily start out by learning and doing the Lord's law (myrrh). The Lord can then call up those memories to become rational truths (frankincense). Then, over time, and with effort, those truths can be transformed into good (gold). The wise men from the East had gone through this process of learning and becoming vessels that could receive truths and goods. They were able to perceive the Lord's birth, and find him, and bring gifts to him.

939. The ideas comprising the thought of people who have been disgustingly avaricious are converted into disgusting delusions. How disgusting is clear from their hell, which is deep down underfoot. A steamy vapour exudes from it like that coming from pigs whose bristles are being scraped off in a trough [of hot water]. It is here that the greedy have their dwelling-places. At first the appearance of those who enter that place is black. But then on being shaven like pigs they seem to themselves to become shining white. This is how they appear to themselves at this point, but a mark is nevertheless left after shaving to indicate their true character wherever they go. A certain black spirit who had not yet been taken down into his own hell because he was required to stay on longer in the world of spirits was sent down to where they were. He had not been so avaricious a person, but nevertheless during his lifetime he had gazed with envy and evil intent at other people's wealth. As he drew near, the avaricious people there fled, saying that as he was black he was a robber who, being such, would murder them. For the avaricious flee from such people, fearing greatly for their own lives. At length however they learned that he was no such robber and they then told him that if he wished to become shining white he had merely to get rid of the hair covering him, like the pigs which were in full view, and he would then be shining white. But he did not wish to, and so he was taken up to be among spirits.
