Step 1: Understanding the Concept:
In Muhūrta Śāstra (Electional Astrology), the 27 Nakṣatras are classified into seven groups based on their inherent nature and the activities they support. One of these groups is 'Dhruva' (Fixed) or 'Sthira'. These Nakṣatras are considered ideal for activities that require permanence, stability, and long-term results, such as building a house, planting trees, or performing a coronation.
Step 2: Detailed Explanation:
The 'Dhruva' Nakṣatra group consists of four specific lunar mansions. According to classical texts like Muhūrta Cintāmaṇi:
1. Rōhiṇī (B): This is the first of the fixed stars. It is ruled by Prajāpati and is associated with growth and stability.
2. Uttarāphālgunī (C): The second 'Uttara' Nakṣatra.
3. Uttarāṣāḍhā (E): The third 'Uttara' Nakṣatra.
4. Uttarabhādrapada (A): The fourth 'Uttara' Nakṣatra.
These four (Rohini and the three Uttaras) form the 'Dhruva' category. Let's evaluate the options:
- Śravaṇa (D): This is classified as a 'Cara' (Movable/Chala) Nakṣatra. It is excellent for travel and vehicles but not for activities requiring 'Dhruva' or static quality.
Therefore, the correct set containing only fixed Nakṣatras is A, B, C, and E. These Nakṣatras are particularly favored for 'Gr̥hapravēśa' (housewarming), 'Upanayana' (sacred thread ceremony), and 'Abhiṣēka' (consecration). If a Sunday coincides with any of these Dhruva Nakṣatras, it creates a special 'Siddha Yōga', making the time highly auspicious. These stars represent the Earth element in their functional application, providing the "gravity" needed to keep a venture stable over many years.
Step 3: Final Answer:
The 'Dhruva' Nakṣatras are Uttarabhādrapada, Rōhiṇī, Uttarāphālgunī, and Uttarāṣāḍhā (A, B, C, E).
