Uttara Ashadha is the twenty-first nakshatra, straddling the Sagittarius-Capricorn boundary from 266 degrees 40 minutes to 280 degrees of the sidereal zodiac. Its Vimshottari ruler is the Sun, its presiding deities are the Vishvadevas, the collective universal gods, and its symbol is an elephant's tusk or a set of planks. The name means the later invincible one. Where Purva Ashadha carries early, forceful victory, Uttara Ashadha carries the final, lasting kind, the win that holds because it rests on righteous foundations and collective support. Jyotisha classes it as Manushya gana and reads it as a mansion of enduring achievement and integrity. These are traditional interpretations laid over the Sagittarius-Capricorn border stars that Indian astronomy counts at this point.
Uttara Ashadha's padas fall in Aries, Taurus, Gemini and Cancer. The Vishvadevas, the collective universal gods, are a Vedic category rather than a fixed roster of specific named deities, sometimes listed as ten, sometimes differently, and their presidency over this mansion, in contrast to Purva Ashadha's more elemental Waters, is read by jyotishis as consistent with Uttara Ashadha's own theme of victory achieved through collective and righteous support rather than through the water's raw unstoppable force alone. The mansion also carries the traditional designation of holding the Abhijit point in its final degrees in certain older reckonings, the extra twenty-eighth mansion of the archaic count, associated with the bright star Vega, a survival of the older twenty-eight-fold scheme embedded within the standard twenty-seven-mansion sequence rather than fully excised from it.
