Hinduism is the dharma that advocates peaceful living taking into cognizance human relation with nature. The cycle of birth and death is only medium for the soul to finally reside in human body to elevate the conscious level to reach Bhagwan (God).
People ignorant of great Hindu Bhakti and tradition simply make mockery of Hindu ethos and rituals without knowing that Sadhus who practice these high conscious tasks take penance to an impossible level which is unimaginable for common people even if they take hundreds of birth in human form.
Naga in Sanskrit means mountain, people residing in and around mountains are known as Pahadi or Naga.
The history of Naga Sadhus is very old, the traces of legacy are found in Mohenjo-daro coins and images where Naga Sadhus are shown worshiping Bhagwan Shiv in Pashupatinath form. Alexandar and his soldiers also met Naga Sadhus during their stay in India. Buddha and Mahavir were impressed to see the penance of Naga Sadhus, their devotion for the people and motherland. Jainese Digambar tradition has roots to Naga rituals.
During invasion of mlecchas (mughals), there were series of attacks on the Sanatan Dharmis and Hindu structures, at that point of time, a massive exercise was carried over by Naga Sadhus to organize their strength and form Akhadas so that they all fight under one Saffron flag to protect Hindu culture and Vedic tradition of India.
