Understand the idea
Sefer Yetzirah is a Jewish mystical text concerned with formation through number and letters. This guide uses selected passages of W. W. Westcott’s 1887 English translation: Chapter I, sections 1–2; Chapter II, sections 1–5; and the supplement to Chapter IV. It is an orientation to those passages, followed by Babylon teaching exercises.
An example to work with
Write three headings: ten sefirot, twenty-two letters, and letter pairs. Put 10, 22, and 231 under the appropriate heading. Then explain why a fixed path and a two-letter Gate are different structures in Babylon.
What to notice in the selected passages
The opening sets out thirty-two paths of wisdom and distinguishes ten sefirot from twenty-two letters. The letters are grouped as three Mothers, seven Doubles, and twelve Simples. Chapter II discusses joining letters and the 231 entrances or Gates. The supplement to Chapter IV gives particular planetary pairings. Those pairings differ from Babylon’s adopted table.

For Babylon’s mathematical directory, take twenty-two distinct letters and choose two different letters at a time. Each letter can meet twenty-one others: 22 × 21 counts 462 ordered meetings. Dividing by two removes the duplicated reverse order, leaving 231 unique pairs. This calculation explains a directory size. It does not supply a distinct interpretation for every pair.

In the learning centre, the ten stations are fixed reference points. The twenty-two paths are letter corridors connecting stations. A paired Gate is a meeting of two letters. A student can therefore study the Aleph path and Aleph–Bet without making them the same entry. Babylon’s card images, current action words, and daily selection rules belong to its interpretive framework.
Explore the connected lesson ↗A first lesson with Aleph–Bet
Begin with a purpose that needs a container: a study group needs a time, a place, and an understandable lesson. In Babylon’s Aleph–Bet exercise, breath and house become a question about intention and structure. Ask which part of the arrangement helps the purpose, and which part has become an obstacle. Let the learner change one practical detail and report what happened.
Explore the connected lesson ↗Teach the edition and the interpretation
Name the translation when discussing a passage. When explaining Babylon, use the current Babylon vocabulary and identify it as such. A useful lesson can place a short account of the passage beside an original example, then ask learners to explain how the example uses the structure. Agreement on a number does not establish that every later interpretation appears in the text.
