Utpanna Ekadashi in the Hindu calendar is the eleventh day (ekadashi) of the dark (waning) half of the lunar month of Margashirsha (November–December) is a religious celebration.
This, like all of the eleventh-day observances, is devoted
to the worship of Vishnu, particularly in his appearance as Krishna on this
day.
Most Hindu festivals have mandated ceremonies, which
generally include fasting (upavasa) and devotion, and frequently offer
particular rewards for loyal participation.
Those who take this vow should fast completely on the tenth
day and offer full devotion on the eleventh day's brahma muhurta.
Only fruits should be presented to the god on this ekadashi.
It is thought that observing this event faithfully brings
spiritual liberty (moksha).
The term Utpanna means "birth," and the founding
tale for this festival is Anasuya, the sage Atri's wife.
Anasuya is well-known for her love to her husband, and the
gods' wives are envious of her.
The gods come asking for food, but Anasuya refuses to give
it to them unless she offers it to them nude.
Lakshmi, Parvati, and Saraswati send their husbands (Vishnu,
Shiva, and Brahma) to attempt to compromise her faithfulness.
Anasuya transforms the three gods into newborns and feeds
them until they are pleased, using the power she has received through her
devotion to her husband; these three gods are eventually "born" into
her household: Vishnu as Dattatreya, Shiva as Durvasas, and Brahma as Chandra.
