In solar religious calendars, Agrahayana (or Margaḻi in Tamil traditions) begins with the Sun's entry into the zodiac sign Sagittarius (Dhanus Rashi) and is considered the ninth month of the year.
Additionally, the 10th Canto, 22nd Chapter of Bhagavata Purana narrates a significant episode where the young, marriageable daughters of the cowherd men of Gokula (gopis) worship goddess Katyayani.
This day is commemorated with special prayers, rituals, and offerings dedicated to Bhairava, who is regarded as the protector and guardian deity.
This fast is observed on all Thursdays of the Margashirsha month in the Hindu lunar calendar, totaling four days of devotion and prayer.
The fast holds special significance, as it is associated with wealth, prosperity, mental and spiritual growth, making it ideal for invoking goddess Lakshmi’s blessings.
