आगमे विश्वासटिप्पन्यः

Festival falling on the eleventh day
(ekadashi) of the dark (waning) half of
the lunar month of Bhadrapada
(August–September). As are all of the
eleventh-day observances, this is dedicated to the worship of Vishnu. Most
Hindu festivals have certain prescribed rites, usually involving fasting
(upavasa) and worship, and often
promise specific benefits for faithful
performance. The most important
requirement for this festival is to pass
the night in worship; taking part is
believed to free one from all evil. The
name Aja means “unborn” and is one
of the epithets of Vishnu.
