The Elemental Nature of Each Planet
"The Sun is the source of all vital heat and light. It is intrinsically benefic by generating life, but can be accidentally malefic if its heat is excessive (combustion) or if it is determined to houses of destruction."— Astrologia Gallica, Book XIII
it is the physical mechanism by which planets act on the sublunar world.
Sun — Hot and dry (moderate). Source of vital heat. Intrinsically benefic. Can burn (combustion) when too close.
Moon — Cold and humid. Governs physical matter and the vegetative soul. Plastic and mutable — she adopts the nature of any planet she receives.
Saturn — Excessively cold and dry. The great malefic. Restricts, consolidates, delays. In good celestial state and angular, produces depth and authority, not evil.
Jupiter — Moderately hot and humid. The great benefic. Expands, preserves, elevates. His malice, when determined to harm, enlarges problems rather than creates them.
Mars — Excessively hot and dry. The lesser malefic. Cuts, separates, inflames. His evil is active and violent, unlike Saturn's passive and restrictive malice.
Venus — Temperately cold and humid. Lesser benefic. Promotes union, pleasure, harmony.
Mercury — Neutral and convertible. Adopts the nature of planets in aspect or the sign it occupies. Treat Mercury as a variable whose charge (+/−) depends entirely on its associations.
Essential Dignities: The Celestial State
"The strength of a planet depends primarily on its relationship to the Zodiac. Domicile is the maximum dignity. A planet in its domicile acts according to its own nature and has the force to fulfill what it promises."— Astrologia Gallica, Book XV
comes from three dignities only — and eliminates terms and faces entirely.
Domicile (+5) — Maximum dignity. The planet acts freely according to its own nature and has the force to deliver what it promises.
Exaltation (+4) — Secondary dignity. Indicates brilliant or sudden strength, but perhaps less stable than domicile.
Triplicidad (+3) — Morin accepts triplicity rulers as valid — but inferior to the above two. Associates with cooperative support and general facilitation.
REJECTED by Morin: Terms (Egyptian and Ptolemaic) and Faces — he calls them "fictions without natural foundation." The AI engine of TheAstroKind follows this Morinian correction.
Detriment (−5) — Planet in the opposite sign of its domicile. Weakened, constrained, acts against its own nature.
Fall (−4) — Planet in the opposite sign of its exaltation. Humiliated, lacks expression.
Celestial State vs. Terrestrial State
"The heaven is the universal cause; the horoscope is the particular cause; the event is the effect of the determination of the first upon the second."— Astrologia Gallica, Book XXI
all interpretation collapses into meaningless symbol-juggling.
Celestial State (Estado Celeste): The intrinsic quality of a planet's influence — good, bad, or mixed — determined by its essential and accidental dignities.
This is *universal*: a planet in good celestial state produces good effects regardless of the house it's in (with exceptions for malefics in houses VI, VIII, XII).
Terrestrial State (Estado Terrestre): The specific area of life where the planet focuses its quality, determined by which house it occupies and which houses it rules.
This is *particular* to the individual chart.
The key rule: A planet never signifies a concrete event merely by its nature. The Sun signifies "honor" universally — but will only produce honor for a specific native if it is determined toward the house of honor (House X) or rules that house.
Processing hierarchy for any planet:
1. Evaluate Celestial State (quality: good/bad/mixed)
2. Identify Terrestrial Determination (area of life: which houses it occupies/rules)
3. Combine: Quality applied to Area = The Judgment
Classify the Nature of Each Planet in Your Chart
Open your natal chart using the calculator below. For each of the 7 classical planets (Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn), identify: (1) its elemental nature, (2) whether it is benefic or malefic by nature, and (3) whether Mercury changes its nature in your chart and why.
Evaluate the Celestial State of Your Sun
Find your Sun in the natal chart. Determine: (1) Is it in domicile, exaltation, detriment, or fall? (2) What is its essential dignity score? (3) Is it combust (within 8.5° of the Sun — note: the Sun cannot combust itself)? Apply the dignity scores: Domicile=+5, Exaltation=+4, Triplicity=+3, Detriment=−5, Fall=−4, Peregrine=0.
Separate Celestial State from Terrestrial State
Take Saturn in your chart. First evaluate its Celestial State (what sign is it in? what are its dignities?). Then evaluate its Terrestrial State (what house does it occupy? what houses does it rule by sign?). Write a one-sentence judgment: '[Saturn's quality] applied to [area of life] = [prediction].'
