Naked Hindu ascetics and pilgrims are taking holy dips in sacred rivers in the first major bathing day of the Maha Kumbh festival, which is the largest religious congregation on Earth.

Ash-smeared naked Hindu holy men charged into India's most sacred river Ganges at dawn on the first most significant bathing day of the Kumbh Mela festival (also known as Mahakumbh) in the northern city of Prayagraj. The ascetics chanted religious slogans, invoking Hindu gods and goddesses as they plunged into the icy waters.
