Karkaṭaकर्कट(Karka)
The fourth rāśi (90°–120°), ruled by Chandra; sidereal Crab, water-element, classical movable sign of emotional depth and maternal register.
Karkaṭa
Karkaṭa (कर्कट, also written Karka) is the fourth of the twelve rāśis and the second of the four cara (movable) signs. The word means crab, and the sign carries the creature's defensive sensibility — a soft interior held inside a protective exterior, sideways in approach when direct meeting would be costly. Karkaṭa is ruled by Chandra, the only graha to own a single sign in the Parasari scheme. Bṛhaspati is exalted here at 5°; Mangala is debilitated at 28°.
Classical grounding
Parāśara in Brihat Parāśara Horā Śāstra adhyāya 4 gives Karkaṭa as cara (movable), jala (water) in element, brāhmaṇa in varṇa, and strī (feminine) in polarity. The sign rises pṛṣṭhodaya — hind-part first. The svarūpa is a crab inhabiting water near the shore. In Kālapuruṣa correspondence, Karkaṭa governs the chest and the heart's emotional seat — distinct from the cardiac region assigned to Siṃha in some schemes, which reads the organ at two levels: Karkaṭa for the feeling centre, Siṃha for the physical heart. Karkaṭa-saṃkrānti, Sūrya's entry into the sign, marks the beginning of dakṣiṇāyana — the southern half of the solar year — and is observed across the Hindu calendar.
Significations
Qualities carried by Karkaṭa itself, independent of occupant:
- Cara — movable quality; shares with Meṣa, Tulā, and Makara
- Jala-tattva — water element; shares with Vṛścika and Mīna
- Brāhmaṇa-varṇa — priestly caste in the classical four-fold scheme; shares with Vṛścika and Mīna
- Strī — feminine polarity
- Pṛṣṭhodaya — hind-rising
- Bahu-pāda — "many-footed" in the classical classification, sharing this oddity with Vṛścika; relevant in certain muhūrta rules
The three nakshatras that fall within Karkaṭa are the last pāda of Punarvasu (0°–3°20′; the first three fall in Mithuna), the entirety of Puṣya (3°20′–16°40′), and the whole of Āśleṣā (16°40′–30°), ruled by Bṛhaspati, Śani, and Budha respectively. Puṣya is classically named the most auspicious of the 27 nakshatras for most muhūrta purposes — a quality that colours Karkaṭa's middle segment.
Practical interpretation
A native with Karkaṭa Lagna tends toward emotional depth, strong memory, and a home-centred orientation that the ruler Chandra inclines the chart toward. The Lagna's weight is carried by the Moon's dignity in the natal chart; a strong Moon gives the Lagna its best expression. The 10th bhāva falls in Meṣa, ruled by Mangala and the sign of Sūrya's exaltation, which classically correlates Karkaṭa-lagna natives with public-service or leadership vocations when the 10th is well-supported.
Karkaṭa Chandra — the Moon in its own sign — is a classical strength and the natal placement that gives the Janma-rāśi directly. It is read for emotional resilience and nurture. Puṣya Chandra specifically is named in the tradition for good fortune.
Karkaṭa Sūrya is read as Sūrya in a friend's sign — Sūrya and Chandra are mutual friends in the naisargika tables — which gives the placement reasonable dignity without the full strength of own-sign or exaltation. The register tends toward authority expressed through care for others rather than through direct command.
