This world is Satan's stage of action, and spirit world God's stage of action; as such the two worlds have been always in confrontation. Since this surely remains as a sorrow in the Age of Restoration, we cannot let them continue in opposition to each other. We should establish the realm of the mind centering on God and realm of body governed by God. You should know that securing the foundation of unification depends on how you develop this in your daily life. (45-213)

In order to unify the Unification Church, we should unify the spirit world. Do you know spirit world? [Yes] Our Unification folks should understand spirit world and unify it. Do you think it is easy to unify it? Without unification of the spirit world, there is no unification of the world on earth. You know that the fight in the world on earth is hard, right? Then, do you think the fight in the spirit world would be easier? [Harder] Considering this, our Unification members cannot speak about hardship, since I am going forward myself. (153-56)

In the search for an ideal, what makes the physical and spiritual affairs one? For the sake of the unification of the two realms, things have to be switched around. If I hold on to my own, it will not work. I have to give everything and then the other side will come along here, and the other side has to give everything, and this side will go along there. We are moving on in order to find the lost place. (147-94)

In connecting the spiritual and physical worlds, we should first confirm and realize deeply our conviction for the world and the ideal of unification, after which we should gratefully take the suffering path in order to realize it worldwide. Then the spiritual and physical worlds will automatically become one, and unification will start from there. The direction of unification will be decided there. (29-285)

Can the Unification Church unify the world on earth before unifying the spirit world? [No] That is the Principle. For this reason, in order to unify the spirit world, I am driving the Unification members into a place of death mercilessly. Then spirit world will have to help you. The more miserable place you go into, the more the spirit world will be united. Do you see this? [Yes] When you go into a deep place, the realm of the heavenly kingdom will be open among the thirty million Korean people. Do you see this? This realm includes those who are in hell. (49-109)
