Hindu Śaiva ascetic who belongs to one of the 10 orders (daśnāmī, “ten names”) established by the philosopher Śaṅkara in the 8th century AD and still flourishing in India today. The 10 orders are Araṇya, Āśrama, Bhāratī, Giri, Parvata, Purī, Sarasvatī, Sāgara, Tīrtha, and Vana. Each order is attached to one of four monasteries (maṭhas), also established by Śaṅkara, in the north, south, east, and west parts of India. They are Jyoti (Joshi) Maṭha (at Badrīnāth, near Haridwār, Uttar Pradesh state); Śṛṅgeri Maṭha (Sringeri, Karnataka state); Govardhana Maṭha (Puri, Orissa state); and Śāradā Maṭha (Dwārka, Gujarāt state). The heads of the monasteries are called mahants (the head of the Śṛṅgeri Maṭha is called jagadguru, “teacher of the world”); they continue to be consulted on points of doctrine and to be accorded the highest respect by Hindu laymen as well as by the ascetics who follow them.

Daśnāmī sannyāsins typically wear ochre-coloured robes and, if they can obtain one, carry on their shoulders a tiger or leopard skin to sit on. They wear a mark (tilaka), ideally made with ash from a cremation fire, consisting of three horizontal bands across the forehead and on other parts of their body, and a necklace-rosary consisting of 108 rudrākṣa seeds. They allow their beards to grow and wear their hair loose about their shoulders or else tied in a topknot.

Some extreme daśnāmīs go about naked. They are called nāgā (“naked”) sannyāsins and are the most militant among the ascetics. In the past the nāgā sannyāsins on occasion engaged in battles with Islāmic fanatics and with the naked ascetics of other Hindu sects.
