The Kailaasa Paramparagatha Mahanirvani Peetham (Mahanirvani Akhada) is the oldest apex body of the Sanatana Hindu Dharma, which governs over 10 million Aghoris, Sanyasis and Naga Sadhus among other ancient religious orders. Haridwar is the current spiritual of the Mahanirvani Akhada. Earlier Varanasi was the spiritual headquarters where Sri Kapila Mahāmuni’s Māhā Jīvasamādhi (final enlightened resting place) is located.

The spiritual head of Mahanirvani Akhada is known as Ācārya Mahāmanḍaleśvar. He is elected by the Mahāmanḍaleśvars of the Akhāḍā, and his is a lifetime position and responsibility. Currently, the Mahanirvani Akhada has 46 Mahāmanḍaleśvars (spiritual pontiffs). The top administrative body of the Akhāḍā is Shree Panch (the body of five) also known as Pancheshwar, representing Brahma, Viṣṇu, Śiva, Shakti and Gaṇeśa.

The Mahanirvani Akhada as the direct representative of the presiding deity of Sri Paramaśiva governed the whole of Indian kingdom from North to South, East to West with its great ancient kingdoms starting from the Himalayas, the Kuru dynasties at Hastinapura (present day Delhi, India) to Southern kingdoms such as Kanchi, Lanka, to Saurashtra, Dwaraka in the West India.
