The head is the part of us that is highest, which means in a representative sense that it is what is closest to the Lord. Because of this the head represents what is inmost in us, the thing at the center of our being. In most cases this means intelligence and wisdom, since most of us are in a state of life in which we are led by our thoughts and reason. In the case of the Lord, however, it often represents His perfect love. And in many cases the head is used to represent the whole person.

3168. 'And they ate and drank' means making one's own the good and truth introduced in this way. This is clear from the meaning of 'eating' as being communicated and joined together, thus being made one's own, dealt with in 2187, 2343, and more specifically (since 'eating' has reference to bread and 'bread' means good, 276, 680, 2165, 2177, 2187) making good one's own; and from the meaning of 'drinking' as being communicated and joined together, thus being made one's own, dealt with in 3089, and more specifically (since 'drinking' has reference to wine and 'wine' means truth, 1071, 1798) making truth one's own. The situation is as stated above in 3167, namely that when truth is introduced into good in the rational, more so when it is joined to it, the good and truth of the spiritual man, that is, spiritual things, become made over to the natural as its own.
