The Zohar, Chapter “Tazria (When A Woman Delivers),” Item 150: When one begins to build a house, he should mention in his mouth that he is building it for the work of God.
The Zohar speaks about our spiritual work. Not a single word of it pertains to the realm of this world with its material objects, such as houses, rocks, animals, or plants. The Zohar explains the inner work of a person needed to reach the revelation of the Creator in the part of the soul called “human,” the “point in the heart.”
It is a new sense that we need to reveal and build, replacing senses of reception with a bestowing sense, called a “soul,” “home,” or “collection of the souls of Israel” (Malchut). This sense has many names depending on what property we want to discern and highlight.
The Zohar explains this through the example of building a house, that very sense in which we reveal spiritually. A spiritual sense (a vessel, Kli) that we need to build should be flawless. If there is a flaw inside this Kli, meaning, there is an intention for the sake of reception rather than for the sake of bestowal, the Light vanishes immediately.
Such a state is called an “afflicted house” (Nega). Then we need to correct this Kli by burning, destroying, or, in case it is possible to cleanse it and make it fit for use, by correcting it. As a result, Nega (curse) turns into Oneg (delight).
A person that built his Kli improperly, by mistake or negligence, needs to understand where it comes from. In this manner, one advances through corrections.
