Astrology » Aspects
All physical planets aspect 7th sign from themselves.
Mars additionally aspect 4th and 8th signs from itself.
Jupiter additionally aspect 5th and 9th signs from itself.
Saturn additionally aspect 3rd and 10th signs from itself.
Rāhu and Ketu, being non-physical planets, cast no aspect.
Unlike in Western Astrology where aspects are considered degree to degree, in Indian Astrology aspects are considered sign to sign. If Jupiter is at 29° Pisces and Saturn is at 1° Aries, they are not considered to be conjunct or influencing each other. But if in the same scenario, Mercury is at 29° Aries, Saturn and Mercury are considered to be conjunct and influencing one another. This proposition needs to be verified.
Generally, the strength of aspect for a planet is:
1st from itself — 100% = 60 Virupas
2nd from itself — Negligible
3rd from itself — 25% = 15 Virupas
4th from itself — 75% = 45 Virupas
5th from itself — 50% = 30 Virupas
6th from itself — Negligible
7th from itself — 100% = 60 Virupas
8th from itself — 75% = 45 Virupas
9th from itself — 50% = 30 Virupas
10th from itself — 25% = 15 Virupas
11th from itself — Negligible
12th from itself — Negligible
Note that Mars casts extra 25% aspect to 4th and 8th signs each from itself
whereas Jupiter (next farthest planet) casts extra 50% aspect to 5th and 9th signs each from itself
while Saturn (next farthest planet) casts extra 75% aspect to 3rd and 10th signs each from itself.
i. If Mars casts extra aspect to 4th and 8th, its aspect on other houses (except 1st and 7th) should diminish or remain same??
ii. If Jupiter casts extra aspect to 5th and 9th, its aspect on other houses (except 1st and 7th) should diminish or remain same??
iii. If Saturn casts extra aspect to 3rd and 10th, its aspect on other houses (except 1st and 7th) should diminish or remain same??
iv. It seems from this scheme that Uranus aspects additionally 2nd and 11th signs from itself
while Neptune aspects additionally 6th and 12th signs from itself (not applied or verified yet)
A Fixed Sign aspects all Cardinal (Movable) signs except the one adjacent to itself. In other words, a Fixed sign aspects 3rd, 6th and 9th sign from it.
A Cardinal (Movable) sign aspects all Fixed signs except the one adjacent to itself. In other words, a Cardinal sign aspects 5th, 8th and 11th sign from it.
A Dual (Mutable) sign aspects all other Dual (Mutable) signs. In other words, a Dual sign aspects 4th, 7th and 10th sign from it.
Hence, each sign (Rāshi) aspects exactly 3 signs in the Jaimini system. Thus, a planet aspects other planet(s) in the sign(s) aspected by the sign it occupies in the chart.
Note that in both Parāshara and Jaimini systems, 2nd and 12th houses are unaspected, whereas in Jaimini system, 6th house from a Fixed sign is aspected, and 11th house from a Cardinal sign is aspected.
