Rishikesh in the context of "Dehradun"

Samādhi (Pali and Sanskrit: समाधि), in the Indian religions, is a state of meditative consciousness. In many such traditions, the cultivation of samādhi through various meditation methods is essential for the attainment of spiritual liberation (known variously as nirvana, moksha).

In Buddhism, it is the last of the eight elements of the Noble Eightfold Path. In the Ashtanga Yoga tradition, it is the eighth and final limb identified in the Yoga Sutras of Patanjali. In Jain meditation, samadhi is considered one of the last stages of the practice just prior to liberation.

Tapovana (Sanskrit) comes from the two root words tapas, meaning 'penance' and by extension 'religious mortification' and 'austerity', and more generally 'spiritual practice', and vana, meaning 'forest' or 'thicket'. Tapovana then translates as 'forest of austerities or spiritual practice'. Though pronounced the same in Hindi, tapovana should not be confused with tapovan (from tapovat), which means a person engaged in austerity.

Traditionally in India, any place where someone has engaged in serious spiritual retreat may become known as a tapovana, even if there is no forest. As well as particular caves and other hermitages where sages and sadhus have dwelt, there are some places, such as the western bank of the northern Ganges river around Rishikesh, that have been so used by hermits that the whole area has become known as a tapovana.

Bhabar or Bhabhar is a region south of the Lower Himalayas and the Sivalik Hills in Garhwal and Kumaon, India. The Bhabhar region contains some of the largest cities of Kumaon and Garhwal: Dehradun, Haridwar, Haldwani, Rishikesh, Ramnagar, Tanakpur and Kotdwar. It is the alluvial apron of sediments washed down from the Sivaliks along the northern edge of the Indo-Gangetic Plain.

The Indo-Gangetic Plains are generally thought of as a flat region with no variations, although this is not true. The plains can be classified into four regions on the basis of relief features. The Bhabar is a belt of 8–16 km lying parallel to the slopes of the Sivaliks, where the river descending from the mountains deposit pebbles. The streams flow through the pebbles the region, hence disappearing from sight. They re-emerge only after some distance south, in the relief feature Terai.

Swami Sivananda Saraswati (IAST: Svāmī Śivānanda Sarasvatī; 8 September 1887 – 14 July 1963), also called Swami Sivananda, was a yoga guru, a Hindu spiritual teacher, and a proponent of Vedanta. Sivananda was born in Pattamadai, in the Tirunelveli district of modern Tamil Nadu, and was named Kuppuswami. He studied medicine and served in British Malaya as a physician for several years before taking up monasticism.

He was the founder of the Divine Life Society (DLS) in 1936, Yoga-Vedanta Forest Academy (1948), and the author of over 200 books on yoga, Vedanta, and a variety of subjects. He established Sivananda Ashram, the headquarters of the DLS, on the bank of the Ganges at Muni Ki Reti, 3 kilometres (1.9 mi) from Rishikesh, and lived most of his life there.

Dehradun district (Hindi: [d̪eːɦɾaːd̪uːn] ) is a district in Garhwal which is a part of Uttarakhand state in northern India. The district headquarters is Dehradun, which has also served as the interim capital of Uttarakhand since its founding in 2000. The district has 6 tehsils, 6 community development blocks, 17 towns and 764 inhabited villages, and 18 unpopulated villages. As of 2011, it is the second most populous district of Uttarakhand (out of 13), after Haridwar. Dehradun district also includes the prominent towns of Rishikesh, Mussoorie, Landour and Chakrata. The district stretches from the Ganges river in the east to the Yamuna river in the west, and from the Terai and Shivaliks in the south and southeast to the Great Himalaya in the northwest. During the days of British Raj, the official name of the district was Dehra Dun. In 1842, Dun was attached to Saharanpur district and placed under an officer subordinate to the Collector of the district but since 1871 it is being administered as separate district. Dehradun district's Jaunsar-Bawar are culturally part of the historical Mahasu region.

Dehradun is located 230 km from the national capital, Delhi. The National Oil and Natural Gas Corporation, Survey of India, and many educational institutions like Doon University, Uttrakhand Technical Institute, Indian Institute of Petroleum, Uttaranchal University, Forest Research Institute, Wildlife Institute of India, Rashtriya Indian Military College and Indian Military Academy are also situated here. Basmati rice, tea and litchi orchards are some of the major agricultural crops.
