Kamada Ekadashi, or
eleventh-day, is a festival of Chaitra (March–April), the bright, waxing half of the
lunar month.
Most Hindu holidays have mandated ceremonies, which
generally include fasting (upavasa) and devotion, and frequently offer
particular rewards for loyal participation.
As its name implies ("wish-granting"), attending this holiday diligently will grant one's desire (kama), whatever it may be.
