Graha Drishti: Full vs Partial Aspects

 Graha Drishti: Full vs Partial Aspects

Your instinct is right. "Every planet aspects the 3rd, 10th, 4th, 8th, 5th and 9th" is a true statement made incomplete by dropping the word that matters: strength. The classical teaching is graded, not binary.

1. The Parashari scheme (Brihat Parashara Hora Shastra)

Counting inclusively from the planet's house, every planet casts sight in graded strengths:

House from planet	Strength	Virupas (of 60)	Name
3rd and 10th	¼	15	Pada (quarter)
5th and 9th	½	30	Ardha (half)
4th and 8th	¾	45	Tripada (three-quarter)
7th	Full	60	Purna
1st, 2nd, 6th, 11th, 12th	None	0	No drishti

So all planets do see the 3, 10, 4, 8, 5 and 9, but only partially. Only the 7th is a full aspect for every planet.

2. Where the "special" aspects come in

Three planets have their partial aspect raised to full strength:

• Mars: the 4th and 8th go from ¾ to full (+15 virupas).
• Jupiter: the 5th and 9th go from ½ to full (+30).
• Saturn: the 3rd and 10th go from ¼ to full (+45).

Each one's special aspect lies where the ordinary partial aspect is weakest-to-strongest in a pattern that suits its nature. Saturn is the slow planet whose reach goes furthest in fullness. Jupiter gets the trines, the houses of dharma. Mars gets the squares, the houses of conflict and home.

The popular claim "Mars aspects 4, 7, 8" is therefore a compression. The full truth is that Mars sees the 4th and 8th at three-quarters like everyone else, and gains the remaining quarter as his special grant.

3. Aspects are continuous, not just by house

In Shadbala (Drishti Bala), the strength is computed from the actual angular distance, so the aspect rises and falls smoothly. The classical formula, with d as the angle in degrees from the aspecting planet to the target:

• 0–30°: 0
• 30–60°: (d − 30) ÷ 2
• 60–90°: (d − 60) + 15
• 90–120°: (120 − d) ÷ 2 + 30
• 120–150°: 150 − d
• 150–180°: (d − 150) × 2
• 180–300°: (300 − d) ÷ 2
• 300–360°: 0

This gives 15, 45, 30 and 60 virupas at 60°, 90°, 120° and 180° respectively. Past 180° it descends to 45 at 210° (the 8th), 30 at 240° (the 9th), and 15 at 270° (the 10th). Mars, Jupiter and Saturn then add their special bonuses in those zones. The consequence is that a "full" aspect in house terms may be only partial in degrees. A planet at 29° of its sign aspecting a planet at 1° of the 7th house is much closer to exact than one at 1° aspecting 29°.

4. Other systems use different logic

• Jaimini (Rashi Drishti): aspects belong to signs, not planets, and are all-or-nothing. Movable signs aspect all fixed signs except the adjacent one. Fixed signs aspect all movable signs except the adjacent one. Dual signs aspect the other dual signs. Every planet in that sign shares the sign's sight, and there are no fractions.
• Tajika (annual charts): aspects are classed by quality, not just by strength. The 3rd, 5th, 9th and 11th are friendly. The 4th and 10th are hostile. The 1st and 7th are inimical. These are read together with orbs (deeptamsa) and are used to judge whether a promise in a chart will be fulfilled.
• Rahu and Ketu: the sources disagree. Many use the 5th and 9th (like Jupiter), some add the 7th, and a few add the 2nd and 12th. Parashara himself is not explicit, so treat this as a school-dependent choice.

5. How to apply this in reading

1. Nature of the aspecting planet colors the aspect. A benefic aspect protects or nourishes the house. A malefic aspect pressures it. Strength shows how much, nature shows what kind.
2. Aspects work on houses and on planets. A planet aspects the house itself (its significations) and any planet in it.
3. Partial aspects are real but quiet. A ¼ aspect from Venus on the 10th is a whisper. A full Saturn aspect on the same house is a verdict. Practitioners who treat all aspects as equal over-read the minor ones.
4. Aspect is not conjunction. Conjunction blends the two planets' natures in one place. Aspect is influence at a distance, so the aspecting planet does not lose its own house results.

6. An honest note on practice

Many modern teachers use only the full aspects (7th for all, plus the three special ones) and ignore partial aspects entirely. Classical texts and Shadbala computation do use the graded scheme. Both approaches are in use, so which one you adopt should depend on the lineage you follow.

So the full statement is this: every planet sees the 3rd, 10th, 4th, 8th, 5th and 9th with graded partial strength, and the 7th in full. Only Mars, Jupiter and Saturn see their special houses in full.
