12 In that place they shall forget this world. There they have no want; and they shall love one another with an abundant love. In their bodies there shall be no heaviness, and lightly shall they fly as doves to their windows. In their thoughts they shall not there remember wickedness at all, nor shall anything of uncleanness arise in their heart. In that place there shall be no natural desire, for there they shall be weaned from all appetites. There shall not arise in their heart anger or lasciviousness; also they shall remove from them all things that gender sins.
Fervent in their heart will be the love of each other; and hatred will not be fixed within them at all. They shall have no need there to build houses, for they shall abide in light, in the mansions of the saints. They shall have no need of woven raiment, for they shall be clothed in eternal light. They shall have no need of food, for they shall recline at His table and be nurtured for ever. The air of that region is pleasant and glorious, and its light shines out, and is goodly and gladsome.
Planted there are beautiful trees, whose fruits fail not, and whose leaves fall not. Their boughs are glorious, their perfume delightful, and of their taste no soul shall grow weary for ever. Spacious is the region, nor is it limited; yet its inhabitants shall see its distance even as that which is near. There the inheritance shall not be divided, and no man shall say to his fellow:— “This is mine and that is yours.” They shall not be bound there in the desire of covetousness, nor shall they go astray there concerning remembrance.
There a man shall not love his neighbour with special reverence, but abundantly shall they all love one another after one fashion. They shall not marry wives there, nor shall they beget children; nor shall there the male be distinguished from the female; but all shall be sons of their Father Who is in heaven; as the Prophet said:— Is there not one Father of us all; is there not one God Who created us?
