You hit on a significant portion of Dramatica and Kabbalah by mentioning Tzimtzum. You're probably already aware of the stages of energy flow within the Tree of Life. I see it also as like the creative story process.
I'd still have to think about the first sefirah, Keh-tehr ("Crown"), but the next one, Khokhmah, acts like a father by spewing a flood of inspiration. Unfiltered. I link this with a singularity. The next sefirah, Bee-nah ("Understanding"), receives and incubates this energy into form and shape. All three of these sefirot are the top triumvirate of the Tree of Life, dealing with the mind.
As a writer, this directly connects with receiving a burst of inspiration and having to use Dramatica's Storyforming stage to break apart this singularity into component parts through labels. Recall those "multi-appreciation moments" when several variables in a storyform are expressed simultaneously by one moment. Perhaps this is a subconscious remnant of when they were a singularity.
So Storyforming could be seen as the sefirah stage of Binah (bee-nah). When does the Story Encoding, the second stage of Dramatica's Storytelling, occur? I suppose Encoding coud be a second mini-stage of Binah.
In the Tree of Life, this creative energy then descends toward more physical form to the body of six more sefirot. Thus, the association between the sixth letter of the Hebrew alphabet, vav, and the six sefirot.
Finally, the reproductive organ-like sefirah of Yesod (yeh-sohd) ("foundation") emanates this energy in more materialistic form into the stem of the Tree of Life. This is the sefirah Malkhut ("kingdom") is the tangible world receiving this energy. So, it's paired with the top sefirah, Keter, the most untangible. Therefore, malkhut matches the perhaps much overlooked Dramatica stage of Story Reception. Does the story in received form by audiences match the inspiration given to the writer at the Chochmah (khokhmah) sefirah stage? Regardless of whether it does or not, this story takes on its own identity in the minds of the audience.
In some sense, a writer is a navi. This Hebrew term is translated as "prophet" in English, such as the name of the book "Prophets", but they shouldn't be linked with telling the future. According to the Hebrew Bible, these nevi'im would go into a trance and speak divine statements.
