"The world will end in joy, because it is a place of sorrow. When joy has come, the purpose of the world has gone. The world will end in peace, because it is a place of war. When peace has come, what is the purpose of the world? The world will end in laughter, because it is a place of tears. Where there is laughter, who can longer weep? And only complete forgiveness brings all this to bless the world.In blessing it departs, for it will not end as it began."
The "purpose of the world" originally was to manifest war and tears.
When the purpose upon which it is built, the foundation of it, the reason for it, the cause of it, is uprooted and transformed into a purpose of love.... this actually dismantles the world. Because the world is MADE OF war and death and misery. The world was made as a DEFENSE MECHANISM against reality. When it is no longer seen as a place of war and death and misery, as in the forgiven world, and the mind no longer WANTS to defend itself against reality, "that" world can no longer be maintained. When all souls have seen the forgiven world, it no longer has that PURPOSE. Which is why Jesus says that you'll barely have time to delight at seeing the forgiven world because upon seeing it it no longer has a purpose and you're ready to be scooped up by God.
That doesn't mean it's been given a new purpose like - let's all keep it and love it forever. Instead, the END of its purpose heralds its disappearance. Just as Jesus says that once perception is perfected, perception ITSELF is no longer needed. Perception, and this world, and the body, are nothing but teaching/learning devices. Once the Holy Spirit's purpose of using them to accomplish learning is finished, they no longer even have THAT purpose, and without a purpose the world is nothing. It is over. It has no USE. And so the mind simply drops it and it disappears into nothing.
This is the same mechanism as described in "sickness is a defense against the truth" in which when the PURPOSE of a sickness is recognized, and the mind no longer sees a NEED for that purpose (ie I don't NEED a defense because the truth is not attacking me), it simply recognizes the sickness as pointless and unnecessary and it simply vanishes. Sickness without a purpose cannot stay. Just as the world without a purpose cannot stay.
The world is or was a device for separation, just as is the body. When it is no longer used FOR separation, it no longer is NEEDED, and it no longer is protecting the mind from God. And as such it is cast off. Gone. "The world will spin into the nothingness from which it came."
