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.

5945. 'Take for yourselves from the land of Egypt carts' means matters of doctrine belonging to factual knowledge. This is clear from the meaning of 'the land of Egypt' as factual knowledge, dealt with already; and from the meaning of 'carts' as matters of doctrine. Chariots and horses are mentioned in various places in the Word where Egypt is the subject. There 'chariots' is used to mean matters of doctrine, sometimes false, at other times true ones, while 'horses' is used to mean intellectual concepts, likewise true or false ones. (For the meaning of 'chariots' as matters of doctrine, see 5721.) It is similar with 'carts' there, but matters of doctrine belonging to factual knowledge are meant by them. Matters of doctrine belonging to factual knowledge are religious teachings drawn from the literal sense of the Word, which serve especially those people who are being introduced for the first time to interior truths that the Church possesses, such as the teaching that good should be done above all to widows, to orphans, and to the poor in the streets. Other such religious teachings are contained in the ten commandments. These and many other teachings are matters of doctrine belonging to factual knowledge and are meant by 'carts belonging to Egypt'. Because such matters of doctrine are the first to be learned by a person they also serve him subsequently as a groundwork; for when progress is made towards more internal teachings those learned first become the last and lowest. Moreover celestial and spiritual realities actually terminate in them, for they stand and rest so to speak on the matters of doctrine learned first. Indeed the spiritual world has so to speak its feet and the soles of its feet planted on the natural world; and so far as his spiritual life is concerned a person has his feet planted on matters of doctrine that belong to factual knowledge. The internal sense of the Word rests in a similar way on its literal sense. The particular word for 'carts', by which those matters of doctrine are meant, occurs in only a few places in the Word. It is used in the original language where it is said that the Ark was placed on one, 1 Samuel 6:7; 2 Samuel 6:3; and also when the tabernacle was consecrated, Numbers 7:3. The reason for the use of the word is that 'the Ark' represented heaven, 3478, which stands and rests, as has been stated, on matters of doctrine belonging to factual knowledge.
