Marriage, among the mass of the people, is a physical bond, and this union can only be temporary, since it is foredoomed to a physical separation at the close.
Among the people of Baha, however, marriage must be a union of the body and of the spirit as well, for here both husband and wife are aglow with the same wine, both are enamoured of the same matchless Face, both live and move through the same spirit, both are illumined by the same glory. This connection between them is a spiritual one, hence it is a bond that will abide forever. Likewise do they enjoy strong and lasting ties in the physical world as well, for if the marriage is based both on the spirit and the body, that union is a true one, hence it will endure. If, however, the bond is physical and nothing more, it is sure to be only temporary, and must inexorably end in separation.
When, therefore, the people of Baha undertake to marry, the union must be a true relationship, a spiritual coming together as well as a physical one, so that throughout every phase of life, and in all the worlds of God, their union will endure; for this real oneness is a gleaming out of the love of God.
In the same way, when any souls grow to be true believers, they will attain a spiritual relationship with one another, and show forth a tenderness which is not of this world. They will, all of them, become elated from a draught of divine love, and that union of theirs, that connection, will also abide forever. Souls, that is, who will consign their own selves to oblivion, strip from themselves the defects of humankind, and unchain themselves from human bondage, will beyond any doubt be illumined with the heavenly splendours of oneness, and will all attain unto real union in the world that dieth not.
