Postural yoga in India

Postural yoga began in India as a variant of traditional yoga, which was a mainly meditational practice; it has spread across the world and returned to the Indian subcontinent in different forms. The ancient Yoga Sutras of Patanjali mention yoga postures, asanas, only briefly, as meditation seats. Medieval Haṭha yoga made use of a small number of asanas alongside other techniques such as pranayama, shatkarmas, and mudras, but it was despised and almost extinct by the start of the 20th century. At that time, the revival of postural yoga was at first driven by Indian nationalism. Advocates such as Yogendra and Kuvalayananda made yoga acceptable in the 1920s, treating it as a medical subject. From the 1930s, the "father of modern yoga" Krishnamacharya developed a vigorous postural yoga, influenced by gymnastics, with transitions (vinyasas) that allowed one pose to flow into the next.
Krishnamacharya's pupils K. Pattabhi Jois and B. K. S. Iyengar brought yoga to the West and developed it further, founding their own schools and training yoga teachers. Once in the West, yoga quickly became mixed with other activities, becoming less spiritual and more energetic as well as commercial.
Westernized postural yoga returned to India to rejoin the many forms already in the country, transformed by the pizza effect on its round trip. Western yoga tourists, attracted initially by The Beatles' 1968 visit to India, came to study yoga in centres such as Rishikesh and Mysore. From 2015, India, led by Prime Minister Narendra Modi, held an annual International Day of Yoga, the armed forces and civil service being joined in mass demonstrations by members of the public.
Yoga's ancient spiritual and philosophical goal was to unite the human spirit with the Divine. It was largely a meditational practice; classical yoga such as is described in the Yoga Sutras of Patanjali, written around the second century, mentions yoga postures, asanas, only as meditation seats, stating simply that the posture should be easy and comfortable. The Sanskrit word योग yoga means "yoking, joining".
The branch of yoga that makes use of physical postures is Haṭha yoga. The Sanskrit word हठ haṭha means "force", alluding to its use of physical techniques.
Haṭha yoga flourished from c. 1100. It was practised by Nath and other yogins in South Asia. Its performance was solitary and ascetic. All its procedures were secret. Its objectives were to force the vital fluid prana into the central sushumna channel of the subtle body to raise kundalini energy, enabling Samadhi (absorption) and ultimately Moksha (liberation). Hatha yoga made use of a small number of asanas, mainly seated; in particular, there very few standing poses before 1900. They were practised slowly; positions were often held for long periods. The practice of asanas was a minor preparatory aspect of spiritual work.
By the end of the 19th century, Hatha yoga was almost extinct in India, practised by people on the edge of society, despised by Hindus and the British Raj alike. That changed when Yogendra (starting in 1918) and Kuvalayananda (starting in 1924) along with the establishment of Kaivalyadhama Yoga Institute, taught yoga ostensibly as a means of attaining physical wellbeing, and to study its medical effects, though motivated by a nationalistic desire to show the greatness of Indian culture. They accordingly emphasised the physical practices of Haṭha yoga, the asanas and yoga breathing (pranayama), at the expense of its more esoteric practices such as purifications (shatkarmas), the mudras intended to manipulate the vital forces, and indeed any mention of the subtle body or liberation. They were soon followed by the "father of modern yoga" Krishnamacharya at the Mysore Palace. He experimented with many new yoga asanas and transitions between them (vinyasas), creating a dynamic style of postural yoga. Krishnamacharya observed and adjusted each pupil in an individualised approach to teaching, which later became known as viniyoga. One factor influencing the popularity of yoga as exercise was Indian nationalism; having strong bodies meant being a strong country which could shake off colonial rule. Another was photography: complex body positions could for the first time be captured in a photograph rather than hard-to-follow words.
The 20th century saw a series of yoga gurus establish schools of yoga in India, train yoga teachers, and turn themselves into brands known around the world: Krishnamacharya and his pupils K. Pattabhi Jois and B. K. S. Iyengar, and Sivananda among them. Jois founded Ashtanga Yoga, a vigorous vinyasa style, with its headquarters at the Ashtanga Yoga Research Institute in Mysore. Iyengar founded Iyengar Yoga, a precise style that emphasises correct alignment, using supports where necessary, based at the Ramamani Iyengar Memorial Institute (RIMYI) in Pune. Sivananda and his disciples including Vishnudevananda created Sivananda Yoga, a more spiritual style, based in Rishikesh.
The practice of the medieval seated asanas survived into the 20th century in Calcutta, and was cultivated by Buddha Bose and Bishnu Ghosh. Among Ghosh's pupils was Labanya Palit; she published a manual of 40 asanas, Shariram Adyam ("A Healthy Body"), in 1955, admired by the poet and polymath Rabindranath Tagore. The yoga teacher Bikram Choudhury (born 1944 in Calcutta) claimed falsely to have learnt Hatha Yoga directly from Ghosh; actually he began yoga in 1969, influenced by Ghosh's writings. He emigrated to America in 1971 to found Bikram Yoga. Fleeing legal action in America for sexual abuse and other matters, Choudhury returned to India in 2016, opening several yoga studios.
On its arrival in the West, yoga became mixed with a variety of Western activities and concepts, from gymnastics to psychotherapy, Western occultism and New Age religion. Yoga has grown into a widespread and valuable commodity and form of exercise, ranging from gentle to energetic, and practised by millions across the Western world.
In 1968, the English rock band The Beatles travelled to Rishikesh to take part in a Transcendental Meditation training course at Maharishi Mahesh Yogi's ashram, now derelict and renamed the Beatles Ashram. The visit sparked widespread Western interest in Indian spirituality, and has led many Westerners to travel to India hoping to find "authentic" yoga in ashrams in places such as Mysore (for Ashtanga Yoga) and Rishikesh. That movement led in turn to the creation of many yoga schools offering teacher training and promotion of India as a "yoga tourism hub" by the Indian Ministry of Tourism and the Ministry of AYUSH. Youthful Westerners' sometimes naive spiritual quests to India were gently satirised in the Mindful Yoga instructor Anne Cushman's novel Enlightenment for Idiots.
Yoga, transformed by what the Austrian anthropologist and Indologist Agehananda Bharati called "the pizza effect", having journeyed across the Atlantic and back, returned with new "flavours and ingredients". It had become sleek, modern, a sign of health and fitness and urban cool; it had in large part lost its close association with Hinduism, and had indeed become almost wholly a form of exercise rather than religion of any kind.
In 1992 the anthropologist Sarah Strauss spent 11 months at the Sivananda ashram in Rishikesh, both practising and observing postural yoga in India. The instructors were Indian; the students were American, German, and Indian. She considered that for the Indians, yoga was "embedded in a sense of familial or national belonging", whereas the non-Indians were seeking to "find themselves" in a rapidly globalizing world.
In 2014, the Indian Prime Minister, Narendra Modi, persuaded the United Nations General Assembly to create an annual International Day of Yoga. It has been celebrated since 2015 in many countries, but especially enthusiastically in India. Modi is a member of the right-wing Bharatiya Janata Party (BJP) and of the Rashtriya Swayamsevak Sangh (RSS), a Hindu nationalist volunteer organisation. Critics of Modi have suggested possible motives for the event, from a partisan attempt to make India more Hindu, to the desire to reclaim yoga and have it recognised around the world as "India's cultural property", despite the changes it had undergone. Modi personally led over 35,000 participants on the first Day of Yoga in New Delhi; across India, the Indian Armed Forces ran demonstrations on the decks of warships and high in the Himalayas, while politicians and civil servants from India's large bureaucracy joined events in cities from Chennai to Kolkata and Lucknow.
