1. The central Axiom
"ממצוא חפצך ודבר דבר" (Yeshayahu 58:13): On Shabbos, do not act for your material affairs, and do not speak of them. Silent thought (hirhur) — permitted; matters of Heaven (cheftzei shamayim = Torah, mitzvah, Jewish marriage) — always permitted. Unique distinction in all Hilchos Shabbos: it is not the act that is forbidden, but the mental orientation.
2. Key concepts condensed

| ממצוא חפצך | "Pursuing your affairs" (action) | Forbidden, even without melachah |

| הרהור מותר | "Silent thought permitted" | Talmudic concession (Shabbos 113b) |
| חפצי שמים | Matters of Heaven | Always permitted (Torah, mitzvah) |
| חפצי עצמך | Your own affairs | Forbidden (material, commerce) |
| סכום מקח | Quoting a price | Absolutely forbidden (Rama) |

5. The heart of the siman: הִרְהוּר מֻתָּר and the boundary of speech
Siman ש"ו is unique in all Hilchos Shabbos: what it forbids is not a melachah, not even a material act, but an orientation — toward one's affairs (חֲפָצֶיךָ). Hence the most delicate point: if Shabbos diverts me from my affairs, do my thoughts belong to them? The Gemara (Shabbos 113b) rules: הִרְהוּר מֻתָּר — silent thought is permitted.
Why is thought permitted and speech forbidden?
The pasuk, as the Chachamim read it, contrasts מִמְּצוֹא חֶפְצֶךָ (pursuing your affairs) with וְדַבֵּר דָּבָר (speaking of them). The prohibition therefore touches only what is externalized: uttered speech and visible preparatory acts. Inner thought is not an "overflow" of the affair into the world — that is why the Torah did not include it. The siman does not regulate the mind, it regulates the manifestation of business.
The borderline case: חֶפְצֵי שָׁמַיִם — when the subject overturns the rule
Here is the depth of the siman: the prohibition does not depend on the form (speaking, acting) but on the content. Fully permitted speech — discussing a shidduch, organizing a mitzvah, learning Torah — remains permitted even spoken aloud, because these are not "your affairs" but matters of Heaven. But the boundary is narrow: even for a mitzvah, quoting a numerical amount tips over into the forbidden, because the number is the very hallmark of a commercial act.
6. Mnemonic "חפ"ש" (CHaPaSH)
ח — Cheftzei (חפצי) — "your affairs", forbidden.
פ — Penimi / Pesher — silent thought (hirhur) — permitted.
ש — Shamayim (שמים) — matters of Heaven, always permitted.
— Identifying the nature of the subject = knowing the halachah.

10. Practical commandments of Siman ש"ו
The art of speaking on Shabbos — the checklist
- Before every word: is it cheftzei shamayim or cheftzei atzmecha?
- No prices, no accounting on Shabbos (except strictly mitzvah-related).
- Silent thought about business remains permitted — but the ideal is to think Torah.
- No newspapers, no secular magazines.
- No planning of "after Shabbos" (departure, travel, purchase).
- Mitzvah discussions, shidduchim, study — always permitted and encouraged.
- Machshich al ha-techum only for a mitzvah.
- When in doubt → silence and Torah study.
