How Tarabalam is calculated
To calculate Tarabalam, count forward from your Janma Nakshatra (your birth star counted as 1) to the nakshatra prevailing at the moment of your intended venture, including both stars. Divide this total by nine; the remainder indicates which of the nine Taras applies. If the remainder is zero, it corresponds to the ninth Tara (Parama Mitra).
Because there are twenty-seven nakshatras in the zodiac, this counting cycle repeats three times across the full circle of constellations. These three cycles of nine stars are known as the Paryayas: the first cycle is Prathama Paryaya, the second is Dvitiya Paryaya, and the third is Tritiya Paryaya.
The nature of the nine Taras
Each of the nine Taras carries a distinct energetic influence: 1. Janma (Birth) indicates mixed results, requiring caution during the first cycle; 2. Sampat (Wealth) brings prosperity and gain; 3. Vipat (Danger) indicates setbacks and perils, so it is avoided for important undertakings; 4. Kshema (Well-being) ensures safety, security, and steady growth.
Continuing through the series: 5. Pratyak (Obstacles) brings unexpected resistance and conflicts; 6. Sadhaka (Achievement) empowers accomplishment and fulfillment of desires; 7. Vadha or Naidhana (Destruction) is severely adverse and rejected for auspicious rites; 8. Mitra (Friend) fosters goodwill, alliances, and harmony; and 9. Parama Mitra (Best Friend) grants supreme auspiciousness, success, and joy.
Application in Muhurta and daily life
Astrologers routinely evaluate Tarabalam in conjunction with Chandrabalam (the strength of the Moon sign) before sanctifying times for marriage, housewarming (Griha Pravesha), business inaugurations, signing contracts, travel, and surgical procedures.
When the daily transit nakshatra transitions from one star to the next, the active Tarabalam changes accordingly. Therefore, consulting the exact transition timings in the Panchang ensures that major undertakings are initiated when both lunar and stellar influences are favorably aligned.
