In this week's parsha, Ki Seitzei, we learn the law, that "When you build a new house, you must make a parapet (fence) for your roof, in order that you won't cause bloodshed in your house, by one who falls, falling off of it."
The law of making a parapet applies even when you buy a house that you didn't build, and to an old house as well. So why does the verse say, "When you build a new house?"
Why does the verse call the person who might fall, "one who falls," even though he didn't fall yet? Even more, it is written in the present tense, as if he is presently falling, but he hasn't fallen yet. What kind of person is called, "one who falls?"
The Sifri explains why it says "new," because "from the time it is new, you have to make a parapet." In other words, the obligation to make a parapet begins before you move into the house. The moment it is new to you, whether you built it or bought it, you are obligated to make a parapet. Unlike mezuzah, whose obligation doesn't begin until after you move into the house.
This leaves us with a question. From the words in our verse, "When you build a new house," it seems that the obligation is only for a new house. Why doesn't the verse use terms that indicate, that every house needs a parapet?
The Talmud tells us, that the reason he is called, "one who falls," is because he was already destined to fall.
But you don't have to be the one that makes it happen. Making a parapet, will ensure that it doesn't happen in your house, because when something like that happens in your house, it shines negatively on you.
Again, this leaves us with a question. The word in our verse that means "one who falls," is hanofel, which doesn't refer to someone who is destined to fall, but rather to someone who is presently falling. Who is the one who is presently falling?
Every verse in the Torah is meant to be understood on many levels. When we look deeper into this verse, we can learn lessons that apply to all of us, even to someone who doesn't own a house.
Our sages say, "A man's home is his wife." "When you build a new house," on a deeper level, refers to beginning married life, which is the time that one is first obligated to remove himself from his spiritual cocoon of yeshiva and involve himself in the physical world, to begin making a living. He is therefore actively falling from the spiritual life into the physical world of making a living.
It is at this time that he has to make a parapet. The idea of a parapet, is to set up a fence to protect someone from falling. The parapet he has to make, is new protections and boundaries that will keep him from falling into the trap of being enticed by the physical, and making it more important than the life of Torah. The parapet also provides separation, so that even when he is involved in the physical, he remains separate and holy.
Our purpose is to infuse the physical with G-dliness, making this physical world into a dwelling place for Hashem.
This work primarily begins with marriage, and his obligatory descent into the physical world. It is a mistake to refrain from getting involved in the physical and locking yourself into a spiritual bubble, because if you do, you are not accomplishing what you are meant to. Hashem put you here specifically to develop your part of the physical world, infusing it with G-dliness.
On another level, when you say "house," it refers to the body, every one of us is a soul, and we move into our home, the body. The purpose is the same, to make this world into a dwelling place for Hashem. it is called a "new house," because for the G-dly soul, the physical world is all new. It is "falling," because for the soul it is a great and constant descent, having to deal with the body's natural yearning for physical pleasures, which is not the interest of the soul. At the same time, the soul is happy to be in her new home, because she knows that through the work of the body, making this world into a dwelling place for Hashem, it will draw down levels of G-dliness, beyond anything she experienced before.
How does this work? When we do our part, making this world into a dwelling for Hashem, we are creating for Him a "new home." Everything we do down here affects the spiritual realms as well. We so to speak create a new home for Hashem above. What is new about it, is that there is an expansion in the spiritual realms allowing for levels of G-dliness that before were beyond the loftiest spiritual realms to enter the spiritual realms. And ultimately, we will be able to draw these levels of G-dliness into the physical as well.
To be able to do this work, we have to make a parapet. First, by setting boundaries and protections not to falter, and by creating a degree of separation, so you can be in the world and at the same time, separate.
May we be successful in drawing down G-dliness into the physical, making it a home for Hashem. His presence will fill the world openly, and Moshiach will be here. May it happen soon.
