The Kabbalistic explanation is that the attributes of Atzilus which are Greatness-Kindness, Gevura-Severity, and other attributes “belong to You Hashem,” in the sense that they are bateil- transparent to Hashem and are nothing other than Hashem’s expressions, thus not separate from Him. In addition, they are bateil in the sense of being considered insignificant compared to Hashem, since they have some type of limitation and are the source of the limitations of the creations.
The Tzemach Tzedek notes that this concept is explained in Parshas Vaeira. (The Hebrew quote from that maamar was brought in the footnotes here.) There, the Alter Rebbe explains:
The six attributes of Hashem in Atzilus, Chesed, Gevura etc., are the source of the six directions that define three-dimensional space, which are up, down, right, left, forwards, backwards. Just as these directions exist in physical space, there is “spiritual space” in the spiritual worlds of Beriah, Yetzira, and Asiya.
Both physical and spiritual space (and time) are derived from the attributes of Hashem in Atzilus (Ze’eir Anpin- the source of the six directions; Malchus- the source of time: past, present, and future).
Not only physical space and time needs to reconnect to its source in Atzilus in order to experience Hashem’s Oneness, but also the spiritual space and time needs to reconnect to its source in the attiributes of Atzilus to experience Hashem’s Oneness.
This is the idea of reciting Shema and saying that Hashem is “אֶחָּד -One”: Through this statement and accompanying contemplation we reconnect everything in our life, our physical matters and our Torah and Mitzvah performance, and everything in the entire physical and spiritual worlds, with their source in Hashem’s attributes in Atzilus.
We thereby reveal Hashem’s true Oneness in ourselves and the entire created existence.
What is ‘ְַׁךורָּ ב-blessed/drawn down’ into the world of time and space (עו לָּם וָּעֶד)?
What is ‘ְַׁךורָּ ב-blessed/drawn down’ into the world of time and space (עו לָּם וָּעֶד) is only “the Name of His Glorious Kingdom,” since, for worlds to come into existence that feel separate from Hashem, it is only possible from the attribute of Hashem’s Kingship.
