What happens to the souls of children?

Angels conduct the child's soul to the world of spirits. 

I wish that mothers could see the wonderful sight of that party of angels, conducting the souls of children, instead of weeping, they would sing with joy. They weep, not realising that this separation is short and temporary. 

In a very few years, they will be happy again with their children.

The party of angels then take the child's soul to that beautiful and light-filled part of heaven, which is set apart for children. Here, they care for them and teach them in all heavenly wisdom until gradually the little ones become like the angels.
