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.

1514. Spheres are also made perceptible to the senses by means of odors, which spirits smell far more keenly than men do; for, remarkably, odors correspond to spheres. With people who have given themselves up to the practice of deceit and have as a consequence acquired a deceitful disposition, there is a stink of vomit when their sphere is converted into an odor. With those who have studied how to speak eloquently so that it may all lead to self-admiration, their sphere when converted into something odoriferous is like the smell of burnt bread. With those who have given themselves up to the pursuit of mere pleasure and with whom no charity or faith has existed, the odor of their sphere is that of excrement. It is similar in the case of those who have gone through life committing adultery, whose odor is even more obnoxious. With those who have led lives of intense hatred, of revenge, and of practicing cruelty their sphere, when converted into odors, is the stench of a corpse. From those who have been disgustingly avaricious the stench of mice is given off, and the stench of house-lice or bugs comes from those who persecute the innocent. These odors cannot be detected by anyone unless his interior senses have been opened in such a way that he is at the same time in the company of spirits.
