Some Nagas baba heading toward the Ganges before the bath on the 15th of january in Prayag during the Ardh Khumbh Mela.
Those are part of the Juna Akhara. One of the most prominent Sadhu sects, the Juna Akhara, consists of the warrior-ascetics
or Nagas (the naked). They smear their bodies with holy ash and sport long matted hair, symbolic of their devotion
to Lord Shiva, generally known as the God of destruction, but to Sadhus better known as the Lord of Yoga.
The Nagas importance is emphasised at the Mela as they lead the millions of pilgrims in a procession to
the sandy banks of the Ganges on the main bathing day.
