Interpretive rules
Rules appear here when they cite this source text.
Benefic condition support
Bonifying testimony is surfaced as support only when its contributing ingredients stay visible in the condition balance.
Debilitated composite planetary condition
A body is debilitated when the score and tier show weakness or affliction from visible component testimony, not from an opaque condition label.
Malefic condition pressure
Maltreating testimony is preserved as pressure when visible components lower the condition balance or mark severe impairment.
Planetary aversion
Two bodies whose signs do not join by the classical ray families are surfaced as in aversion at the whole-sign relation layer.
Planetary classical witnessing
Two bodies in signs joined by conjunction, sextile, square, trine, or opposition are surfaced as witnessing by whole-sign ray.
Ptolemaic Ascendant ruler and sect light configure
When the Ascendant ruler and sect light witness one another by whole-sign ray, the chart's governing planet and primary luminary remain directly connected.
Ptolemaic Ascendant ruler and sect light in aversion
When the Ascendant ruler and sect light are in aversion, the governing planet and primary luminary lack a direct whole-sign connection.
Ptolemaic Ascendant ruler in aversion to the Ascendant
When the Ascendant ruler is in aversion to the Ascendant, the chart's governing planet is disconnected from the rising place at the whole-sign level.
Ptolemaic Ascendant ruler in domicile
When the ruler of the Ascendant is in its own domicile, the chart's governing planet is operating from its own sign-based strength.
Ptolemaic Ascendant ruler in exaltation
When the ruler of the Ascendant is in its exaltation, the chart's governing planet is strengthened by the classical exaltation scaffold.
Ptolemaic Ascendant ruler witnesses the Ascendant
When the Ascendant ruler sees the Ascendant by whole-sign ray, the chart's governing planet remains in direct sign-based relationship with the rising place.
Ptolemaic benefic in domicile
A benefic standing in its own domicile is surfaced as operating from one of the clearest classical dignity states.
Ptolemaic benefic in exaltation
A benefic standing in exaltation is surfaced as elevated by a classical dignity state rooted in the Tetrabiblos-era scaffold.
Ptolemaic malefic in domicile
A malefic in its own domicile is surfaced as operating from its proper sign-based strength, without erasing its malefic nature.
Ptolemaic malefic in exaltation
A malefic in exaltation is surfaced as elevated by classical dignity while still retaining its harder native quality.
Ptolemaic sect light in aversion to the Ascendant
When the sect light is in aversion to the Ascendant, the chart's primary luminary is disconnected from the rising place at the whole-sign level.
Ptolemaic sect light in domicile
When the sect light stands in its own domicile, the chart's primary luminary is operating from one of the clearest classical dignity states.
Ptolemaic sect light in exaltation
When the sect light stands in its exaltation, the chart's primary luminary is operating from a stronger classical elevation state.
Ptolemaic sect light witnesses the Ascendant
When the sect light sees the Ascendant by whole-sign ray, the chart's primary luminary remains directly configured with the rising place.
Reception support in planetary condition
Reception is exposed as one supporting component in the planetary-condition balance rather than as automatic rescue.
Strong composite planetary condition
A body is strongly conditioned only when the composite condition tier and score are backed by visible dignity, sect, place, motion, visibility, reception, and joy ingredients.
Visibility impediment in planetary condition
Solar visibility problems are preserved as an impairing condition component even when other ingredients are favorable.
