In the Word, girdles, belts, or sashes (as in Exodus 28:4) stand for good external goals that link the things in our hearts and minds into a state of cooperation and oneness of purpose. 'And a belt' means a common bond to ensure that everything has the same end in view. (Arcana Coelestia 9828) A second meaning is mentioned in Arcana Coelestia 9944, that belts or girdles can create distinct layers, in a way: "a separation from the outward things is also meant is that the bond gathers and holds together within itself the inward things; and this also separates them from the outward ones." In a way, the whole point of trying to accept the Lord and align ourselves with His love and His leading is so that we can express what is good in life -- actually doing things in the world that really benefit other people. These external acts are the lowest form of goodness, but they are the culmination of the higher forms. This has a bonding effect: a whole chain of desires for good and true ideas come together in external action. In some cases, girdles are used to cover the genitals. Since the genitals represent the love of marriage, these girdles represent the external good things that support marriage on all its levels: the marriage of husbands and wives, the marriage of what is good and what is true in each of us as individuals, and the ultimate marriage between each of us and the Lord.

In Revelation 1:13, as another example, there's a description of "one like unto the son of man", who is "girded about the breasts with a golden girdle," symbolizing the "emanating and conjoining Divinity which is Divine good." (Apocalypse Revealed 46)

3638. Consequently in the next life all the communities there, however many these may be, remain in the same fixed position in relation to the Lord, who appears throughout the whole of heaven as the Sun. It is also a marvel - though scarcely anyone will be able to believe it because he is not able to understand it - that the communities there remain in the same fixed position in relation to each individual there, wherever he may be and in whatever direction he turns his body and moves about. Thus communities seen on the right are always to the right of him, and those on the left are always to the left, even though he alters the direction in which his face and body are turned. This I have also been allowed to observe very often by turning my own body. From this it is evident that the form taken by heaven is such that unceasingly it has to do with the Grand Man's existence in relation to the Lord; and that all angels are not only with the Lord but are also in the Lord, or what amounts to the same, the Lord is with and in them, otherwise none of this could ever be so.
