In our fifth lesson (of Part 3) of the Ramchal’s work Derech Hashem, we move deeper into the realm of the soul. The Ramchal brings us into understanding the mystery of G-d’s creating the day and the night. Night is not just a time for sleep. There is more that happens to the soul during this period. It is as much a part of our lives as the day. Whereas the day allows us to attend to our physical matters, the night allows us to explore the spiritual worlds.
