How thin is the veil? Might we remember bits of our experience there? Could a melody we heard there be familiar to us here? (assuming we even heard melodies there). The idea of the pre-existence and of the other elements of the plan of salvation, discussed in D&C Gospel Doctrine lesson 19, are a source of endless wonder and speculation. We just don’t know much about what our existence before and after this life was and will be like. But, perhaps nothing says more about our belief in the plan of salvation than our fascination with speculating about what the life before this one was like, and what the life after this one will be like.
