Step 1: Understanding the Concept:
Each of the 12 houses in a birth chart represents a specific department of human life. This is called 'Bhāva-sphuṭa' or 'Bhāva-artha'. To predict anything about a specific aspect of life, one must examine the corresponding house, its lord (Bhāvēśa), and the significator (Kāraka).
Step 2: Detailed Explanation:
The 5th House is traditionally known as the 'Suta-bhāva' (House of Children) or 'Putra-bhāva'.
1. Scope of the 5th House: Beyond progeny, it represents 'Prārabdha Puṇya' (merit from past lives), intelligence (Buddhi), creativity, mantra-sadhana, and speculation. Children are seen as the fruit of one's past merits and the continuation of one's creative essence, hence their placement in the 5th house.
2. Analysis Method: To determine the happiness from children, an astrologer looks at:
- The strength of the 5th house.
- The position of the 5th house lord.
- The position of Jupiter (Guru), who is the natural Kāraka for progeny.
3. Comparison with other houses:
- 1st House (Lagna): Represents the self, personality, and body.
- 4th House: Represents the mother, vehicles, home, and happiness.
- 9th House: While some South Indian traditions use the 9th house for grandchildren or as a secondary check for children (being the 5th from the 5th), the primary house for children in Parashari astrology is the 5th. The 9th is the house of Dharma and Father.
The Sanskrit dictum: "Pañcamēna sutaṃ vidyāt" — one should know about children from the fifth house. If the 5th house is afflicted by malefic planets like Saturn or Rahu, it may cause delay or denial of progeny. Conversely, benefics like Venus or Jupiter in the 5th usually grant good children and a sharp intellect.
Step 3: Final Answer:
Progeny analysis is done from the 5th House (Pañcama-bhāvāt).
