Question: All desires originate in the world of infinity, but they must manifest in our world and come to a final form. What final form should they take?
Answer: Whether we want it or not, we will have to develop to the very last, highest degree, and feel the whole universe and the Creator who fills it.
The worlds are filters descending from top to bottom and gradually increasingly concealing the upper light or the Creator from us.
Question: So, it is best to imagine them not as parallel worlds but as concealment of the connection of the Creator with creation?
Answer: Yes. In our world this connection is completely hidden from us.
