Step 1: Understanding the Concept:
In Jyōtiṣa, zodiac signs are classified based on their temperament into two categories: 'Krūra' (Fierce/Cruel/Male) and 'Saumya' (Gentle/Soft/Female). This classification is strictly determined by the numerical order of the sign. Odd-numbered signs (1, 3, 5, 7, 9, 11) are Krūra, and even-numbered signs (2, 4, 6, 8, 10, 12) are Saumya.
Step 2: Detailed Explanation:
Let's assign the zodiac numbers to the signs mentioned in the list:
1. Mēṣa (Aries): Sign Number 1. It is an Odd number, so it is Krūra. (A)
2. Karka (Cancer): Sign Number 4. It is an Even number, so it is Saumya. (B)
3. Tulā (Libra): Sign Number 7. It is an Odd number, so it is Krūra. (C)
4. Makara (Capricorn): Sign Number 10. It is an Even number, so it is Saumya. (D)
5. Kumbha (Aquarius): Sign Number 11. It is an Odd number, so it is Krūra. (E)
Therefore, the 'Krūra' signs from the list are A, C, and E. In predictive astrology, 'Krūra' signs represent assertive, active, and dry energies. They are also known as 'Male' (Puruṣa) signs. If a person has their Lagna or many planets in these signs, their personality tends to be more extroverted and enterprising. Conversely, Saumya signs represent receptive, moist, and nourishing energies. This basic division is the foundation for determining the 'Puruṣārtha' or the primary drive of a person's life.
Step 3: Final Answer:
The Krūra signs in the list are Mēṣa, Tulā, and Kumbha (A, C, E).
