Purva Phalguni is the eleventh nakshatra, from 133 degrees 20 minutes to 146 degrees 40 minutes of the sidereal zodiac in Leo. Its Vimshottari ruler is Venus, its presiding deity is Bhaga, a solar god of delight, fortune, and marital happiness, and its symbol is the front legs of a bed or couch. Jyotisha reads the mansion through rest, pleasure, union, and enjoyment, the couch of relaxation and love, consistent with its Venus rulership and Bhaga's association with the good things given. It is classed as Manushya gana. Together with its pair Uttara Phalguni it forms the region the tradition links to marriage and creative leisure. These are interpretive conventions laid over the Leo stars that Indian astronomy counts in this segment.
Purva Phalguni's padas fall in Sagittarius, Capricorn, Aquarius and Pisces. Bhaga is counted among the twelve Adityas of Vedic literature, a solar deity specifically associated with the distribution of good fortune and marital happiness, distinct from the Sun itself though drawn from the same family of solar gods; his presence as presiding deity, alongside the mansion's Venusian rulership, gives Purva Phalguni one of the more thoroughly consistent deity-planet pairings in the whole twenty-seven, unlike several mansions where deity and Vimshottari lord pull in less obviously related directions. The paired Phalguni mansions, front and back legs of a single bed, are among a handful of nakshatra pairs jyotisha reads almost as a single extended unit spanning both signs.
