Step 1: Understanding the Concept:
Every Tithi (lunar day) is governed by a presiding deity (Devatā). This lordship is crucial in 'Muhurta' (electional astrology) and 'Tithi-Vichāra'. Performing rituals or activities related to the deity of the current Tithi is considered highly beneficial. The sequence of lords follows a fixed pattern from Pratipada to Amavasya/Purnima.
Step 2: Detailed Explanation:
According to texts like the Muhūrta Cintāmaṇi and the Śiva Purāṇa, the lords of the first four Tithis are:
1. Pratipada (1st Tithi): The lord is Agni (III). Agni represents the beginning of things, purification, and the first light. This is why many traditional rituals begin on a Pratipada day. (A-III)
2. Dvitiyā (2nd Tithi): The lord is Brahmā (II) (the Creator). This Tithi is considered 'Bhadrā' and is suitable for starting creative and constructive works. (B-II)
3. Tr̥tiyā (3rd Tithi): The lord is Pārvatī (IV) (specifically Gauri). It is an auspicious 'Jayā' Tithi, excellent for marriage-related activities and domestic harmony. (C-IV)
4. Caturthī (4th Tithi): The lord is Gaṇēśa (I). He is the 'Vighnarāja' (Lord of obstacles). Although Caturthī is a 'Riktā' (void) Tithi and generally avoided for major work, it is the most auspicious day for the worship of Ganesha to remove obstacles. (D-I)
The complete list continues as:
5th - Nāga, 6th - Kārttikēya, 7th - Sūrya, 8th - Śiva, etc.
Matching for the question:
- 1st (A) \(\rightarrow\) Agni (III)
- 2nd (B) \(\rightarrow\) Brahma (II)
- 3rd (C) \(\rightarrow\) Parvati (IV)
- 4th (D) \(\rightarrow\) Ganesha (I)
Knowing the Tithi lord helps in personal 'Sādhanā'. For example, fasting or performing a Pūjā on Ganesha Caturthī is a direct application of this astrological principle.
Step 3: Final Answer:
The correct match is A-III, B-II, C-IV, D-I.
