Overview

Tian Tong is a major star used to examine receptivity, restoration, ease, and how available support is accepted or deferred. Read Tian Tong through its actual palace, co-stars, San Fang Si Zheng, Four Transformations, and timing layer. The chart can establish placement; receptivity, ease, restoration, and adaptation to available support remains a bounded interpretive focus, never proof of laziness, lifelong comfort, body shape, or freedom from difficulty.

Definition and scope of Tian Tong

Tian Tong is a major star used to examine receptivity, restoration, ease, and how available support is accepted or deferred.

Tian Tong (天同星) is identified here by Tiān Tóng. Its bounded question is receptivity, ease, restoration, and adaptation to available support, not a fixed personality verdict.

  • Identity check: Tian Tong (天同星) · Tiān Tóng
  • Scope question: receptivity, ease, restoration, and adaptation to available support

Chart evidence and conditions · How to read Tian Tong

Its palace duty, companions, transformations, brightness convention, and pressure from the opposite palace show whether ease supports recovery, avoidance, or flexible adaptation.

Deterministic placement check: iztro「紫微鬥數安星訣」第10節「安紫微諸星訣」:武曲後一宮安天同. After that position is reproduced, ask which palace relations actually support receptivity, ease, restoration, and adaptation to available support; the calculation does not output laziness, lifelong comfort, body shape, or freedom from difficulty.

  • Evidence question: receptivity, ease, restoration, and adaptation to available support

Worked example and near miss

In an illustrative Wellbeing context, Tian Tong supported by Zuo Fu can describe scheduling recovery after a demanding cycle, while repeated postponement elsewhere remains counter-evidence.

Near miss: remove the palace or modifier named in the example but still assert laziness, lifelong comfort, body shape, or freedom from difficulty. That erases the evidence needed to connect Tian Tong (天同星) with receptivity, ease, restoration, and adaptation to available support.

  • Example check: Tian Tong (天同星) · receptivity, ease, restoration, and adaptation to available support
  • Rejected leap: laziness, lifelong comfort, body shape, or freedom from difficulty

School variants and interpretation limits

Classical descriptions sometimes moralize comfort or body traits; responsible reading keeps the claim on coping patterns and never infers health or character from one star.

Historical comparison starts at 《紫微斗數全書》卷一「諸星問答論」1.9.5「問天同星所主若何?」. Read that passage beside the declared placement rule instead of treating one classical phrase as a universal calculator setting.

  • Variant decision: Classical descriptions sometimes moralize comfort or body traits; responsible reading keeps the claim on coping patterns and never infers health or character from one star.

Interpretation limits, boundary, and verification loop

This page may organize questions about receptivity, ease, restoration, and adaptation to available support. It must stop before claiming laziness, lifelong comfort, body shape, or freedom from difficulty; that conclusion needs independent real-world evidence.

Verification loop for Tian Tong (天同星): reproduce iztro「紫微鬥數安星訣」第10節「安紫微諸星訣」:武曲後一宮安天同; inspect the example's named modifier and counter-signals; record what would falsify the reading before using it.

  • Allowed interpretive scope: receptivity, ease, restoration, and adaptation to available support
  • Stop rule: laziness, lifelong comfort, body shape, or freedom from difficulty

Complete topic index

Every workbook topic assigned to this canonical page appears at a stable anchor. Each entry records scope, inputs, flags, and alias ownership as an auditable reference—not a standalone interpretation. Duplicate backlog rows resolve to the same anchor instead of creating duplicate URLs.

Conditions and inputs
  • Missing-input rule: if a listed input or verified chart value is unavailable, stop at the definition; do not infer, calculate, or predict the missing value.
  • Calculation flag: yes. Reproduce the required inputs and versioned rule before interpretation.
  • School-variant flag: sometimes. Check whether the page’s named rule or school condition applies before using this component.
  • School-variant flag: yes. Apply only under an identified school or calculation policy and compare the alternate rule.
  • School-variant flag: no. The workbook does not mark this atom as variant-specific; do not assume universal agreement beyond the cited page sources.
Category and guidance boundary
  • Apply this only under the named calculation or school policy, and compare alternate rules before treating the result as reproducible.
  • Identify the transformed host star, source stem, target palace, and timing layer; a transformation or palace label alone is insufficient.
  • Read this cell as an interaction, not a verdict: combine its entities with co-stars, Four Transformations, palace geometry, brightness, and the active timing layer.
Source inheritance
Complete topic index does not assert an atom-specific citation. It inherits this canonical page’s bibliography and locator notes as page-level context only; verify the relevant cited passage before relying on a claim.
