The eleventh day (ekadashi) of the dark (waning) half of the
lunar month Kartik (October–November) is a religious celebration.
This, like other eleventh-day observances, is devoted to the
worship of the deity Vishnu in his avatar as Krishna on this specific day.
Rambha Ekadashi, like other Hindu holidays, necessitates the
performance of specific ceremonies.
Fasting (upavasa) and devotion are included in these
rituals, which promise special rewards if performed correctly.
Rambha, a renowned apsara or celestial lady in distress, is
honored with this ritual.
Its founding story recounts how a specific king was born in
heaven and served by Rambha and other apsaras after dutifully performing this
procedure.
