Mauni Amavasya, the new moon day in the month of Magh, occurs when the sun and moon enter Capricorn, marking the birth of Manu Rishi and the creation of the universe. Bathing at the Sangam in Prayagraj on this day is considered highly virtuous. Some scholars encourage the practice of Maun Vrat, or a vow of silence, to cultivate control over the senses, which individuals may observe for a day, a month, or even a year.
