Kamika Ekadashi, a sacred Hindu observance dedicated to Lord Vishnu, falls on July 21, 2025. Observing a fast on this day is believed to be highly meritorious, equivalent to performing a thousand Ashwamedha Yajnas. Devotees engage in rituals like chanting Vishnu Sahasranama, reading the Kamika Ekadashi Vrat Katha, and offering prayers to seek divine blessings and cleanse sins.
