Step 1: Understanding the Concept:
In Falit Jyotish (Predictive Astrology), planets exert their influence on other houses through 'Dr̥ṣṭi' (aspects). All planets have a full aspect on the 7th house from their position. However, the outer planets (Mars, Jupiter, and Saturn) possess additional 'Special Aspects' which carry full strength. These special aspects define their unique functional roles in a horoscope.
Step 2: Detailed Explanation:
The rule for planetary aspects is defined in Br̥hat Parāśara Hōrā Śāstra as follows:
1. Universal Aspect: Every planet (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn) aspects the 7th house with \(100\%\) strength.
2. Special Aspects:
- Mars (Bhauma): Aspects the 4th and 8th houses in addition to the 7th. These are known as 'Chaturtha-Ashtama' drishti, signifying protection and transformation/accidents.
- Saturn (Śani): Aspects the 3rd and 10th houses in addition to the 7th. This signifies effort, delay, and professional responsibility.
- Jupiter (Guru): Aspects the 5th and 9th houses in addition to the 7th.
The 5th and 9th houses form the 'Dharma Trikōṇa' (Triangle of Righteousness). Jupiter, being the planet of wisdom, expansion, and divine grace, casts its benevolent influence on the 5th (intelligence, children, past life merit) and the 9th (father, guru, religion, luck). This aspect is considered highly purifying. Even if Jupiter is a functional malefic for a particular ascendant, its special aspects are often believed to protect the houses they touch.
The 7th aspect of Jupiter relates to 'expansion in relationships'. The 5th and 9th aspects relate to 'divine vision' and 'future/past connectivity'. Venus and Mercury only have the 7th aspect. Rāhu and Kētu, in many traditions (like the North Indian Parāśari system), are also attributed the same 5th, 7th, and 9th aspects as Jupiter, though this remains a point of scholarly debate.
Step 3: Final Answer:
The 5th, 7th, and 9th aspect belongs to Jupiter (Guru).
