Writing, Number, & Story

And He created His world with three books: with writing, with number, and with story. - Sefer Yetzirah 1:1
And He created His world with three books: with writing, with number, and with speech. - Sefer Yetzirah 1:1
וּבָרָא אֶת עוֹלָמוֹ בִּשְׁלֹשָׁה סְפָרִים: בְּסֵפֶר, וּסְפָר, וְסִפּוּר.
U-vara et olamo bi-shloshah sefarim: be-sefer, u-sefar, ve-sippur.

Unvocalized Hebrew:

וברא את עולמו בשלשה ספרים בספר וספר וספור

Very literal translation:

And He created His world with three sefarim: with sefer, with sefar, and with sippur.

Smoother literal translation:

And He created His world with three books: with writing, with number, and with telling.

Notes
וּבָרָא
u-vara
and He created
From ברא, “to create.” The opening וּ means “and.”
אֶת
et
[direct object marker]
No direct English equivalent. Marks the thing being created.
עוֹלָמוֹ
olamo
His world / His universe
עולם = world, age, cosmos; -וֹ = his.
בִּשְׁלֹשָׁה
bi-shloshah
with / by / in three
בְּ = in, with, by; שלשה = three.
סְפָרִים
sefarim
books / records / enumerations
Plural of sefer. Here it introduces the triple wordplay.
בְּסֵפֶר
be-sefer
with book / with writing / with text
sefer usually means book, scroll, written text.
וּסְפָר
u-sefar
and number / and counting
Related to counting, numbering, reckoning.
וְסִפּוּר
ve-sippur
and telling / narration / speech / story
From the same S-F-R root; means telling, recounting, narration.

The key is that סֵפֶר / סְפָר / סִפּוּר are all related to the same Hebrew root S-F-R:

סֵפֶר — sefer: book, writing, written text

סְפָר — sefar: number, count, reckoning

סִפּוּר — sippur: telling, narration, story, recounting

So the mystical meaning is something like: Creation happens through writing, number, and telling. Or: through text, number, and story. Or: through book, count, and speech.

And He created His world with three books: with writing, with number, and with story. - Sefer Yetzirah 1:1

That is not the most wooden literal translation, but it preserves the essence better: text, number, and story as the grammar of creation.
