आगमे विश्वासटिप्पन्यः

Festival falling on the eleventh day
(ekadashi) of the bright half of
Margashirsha (November–December).
As for all the eleventh-day observances,
this is dedicated to Vishnu. Most Hindu
festivals have certain prescribed rites
usually involving fasting (upavasa) and
worship, and often promising specific
benefits for faithful performance.
Faithfully observing this festival is
believed to bestow final liberation
(moksha) of the soul.
