• The Zohar (II, 202a) identifies the gladness (Samachti) as the emotional energy that propels the Tzaddik up the third step of the Heikhalot. The invitation to go to the House of Hashem is the community's collective advance toward the Shechinah, and collective movement generates more Sefiratic force than individual effort. The Sitra Achra targets individuals; it struggles against formations.
• "Our feet have been standing within your gates, O Jerusalem!" — the Zohar (III, 145b) identifies the gates as the Sefirah of Malkhut in its aspect of the Sha'ar (gate) to the upper worlds. Standing within the gates means the Tzaddik has already entered Malkhut's domain and is now proceeding inward. The Klipot that guard the exterior perimeter have been passed.
• "Jerusalem — built as a city that is bound firmly together" — the Zohar (I, 195a) explains the binding (Chubrah) as the unification of the Sefirot within the city. A city whose components are unified has no internal divisions for the Sitra Achra to exploit. Jerusalem's spiritual strength is its coherence — every stone connected to every other stone, every Sefirah flowing into every other Sefirah.
• "To which the tribes go up, the tribes of Hashem" — the Zohar (II, 23a) identifies the twelve tribes as twelve configurations of the Sefirot, each representing a different approach to the divine service. When all twelve ascend together, the complete spectrum of holiness is represented, and the Sitra Achra faces a force that attacks from every angle of the spiritual spectrum simultaneously.
• "Pray for the peace of Jerusalem! May they be secure who love you!" — the Zohar (III, 160b) teaches that praying for Jerusalem's peace (Shalom) is praying for the restoration of Yesod's connection to Malkhut. When Yesod and Malkhut are at peace, the Shechinah receives the full flow of divine sustenance, and the Sitra Achra starves. Love for Jerusalem is active participation in the restoration campaign.
• Sukkah 51a describes the Jerusalem Temple complex as the destination of the pilgrimage described in this psalm — the Talmud records that the three pilgrimage festivals were military assemblies as much as worship occasions, the entire nation appearing before God as His army.
• Berakhot 64a connects "Pray for the peace of Jerusalem" (verse 6) to the Talmudic teaching that Jerusalem's peace is the thermometer of the world's spiritual condition — adversarial pressure on Jerusalem is evidence of the Sitra Achra's global agenda.
• Sanhedrin 95b notes that the thrones of judgment (verse 5) in Jerusalem are where the cosmic court convenes — the Talmud reads the city's judicial function as spiritual as well as legal, the place where adversarial claims against Israel are heard and adjudicated.
• Megillah 29a teaches that the Shekhinah never left Jerusalem — even in its destroyed state, the divine Presence remains, making the Sitra Achra's claim that exile represents the end of covenant relationship permanently false.
• Sotah 14a closes with "For the sake of my brethren and friends, I will say, 'Peace be within you'" (verse 8) — the Talmud treats intercession for community as a personal spiritual discipline, the covenant warrior's inner architecture oriented toward the wellbeing of the whole.
