Hatha yoga is a branch of yoga that uses physical techniques to try to preserve and channel vital force or energy. The Sanskrit word हठ haṭha literally means "force", alluding to a system of physical techniques. Some hatha yoga style techniques can be traced back at least to the 1st-century CE, in texts such as the Hindu Sanskrit epics and Buddhism's Pali canon. The oldest dated text so far found to describe hatha yoga, the 11th-century Amṛtasiddhi, comes from a tantric Buddhist milieu. The oldest texts to use the terminology of hatha are also Vajrayana Buddhist. Hindu hatha yoga texts appear from the 11th century onward.
K. Pattabhi Jois was an Indian yoga guru who developed and popularized the flowing style of yoga as exercise known as Ashtanga vinyasa yoga. In 1948, Jois established the Ashtanga Yoga Research Institute in Mysore, India. Pattabhi Jois is one of a short list of Indians instrumental in establishing modern yoga as exercise in the 20th century, along with B. K. S. Iyengar, another pupil of Krishnamacharya in Mysore. Jois sexually abused some of his yoga students by touching inappropriately during adjustments. Sharath Jois has publicly apologised for his grandfather's "improper adjustments".
An āsana is a body posture, originally and still a general term for a sitting meditation pose, and later extended in hatha yoga and modern yoga as exercise, to any type of position, adding reclining, standing, inverted, twisting, and balancing poses. The Yoga Sutras of Patanjali define "asana" as "[a position that] is steady and comfortable". Patanjali mentions the ability to sit for extended periods as one of the eight limbs of his system. Asanas are also called yoga poses or yoga postures in English.
The Sritattvanidhi is a treatise written in the 19th century in Karnataka on the iconography and iconometry of divine figures in South India. One of its sections includes instructions for, and illustrations of, 122 hatha yoga postures.
Ashtanga Namaskara, Ashtanga Dandavat Pranam, Eight Limbed pose, Caterpillar pose, or Chest, Knees and Chin pose is an asana sometimes used in the Surya Namaskar sequence in modern yoga as exercise, where the body is balanced on eight points of contact with the floor: feet, knees, chest, chin and hands.
Modern yoga is a wide range of yoga practices with differing purposes, encompassing in its various forms yoga philosophy derived from the Vedas, physical postures derived from Hatha yoga, devotional and tantra-based practices, and Hindu nation-building approaches.
Yoga as exercise is a physical activity consisting mainly of postures, often connected by flowing sequences, sometimes accompanied by breathing exercises, and frequently ending with relaxation lying down or meditation. Yoga in this form has become familiar across the world, especially in the US and Europe. It is derived from medieval Haṭha yoga, which made use of similar postures, but it is generally simply called "yoga". Academics have given yoga as exercise a variety of names, including modern postural yoga and transnational anglophone yoga.
The Haṭhābhyāsapaddhati is a manual of Haṭha yoga written in Sanskrit in the 18th century, attributed to Kapāla Kuraṇṭaka; it is the only known work before modern yoga to describe elaborate sequences of asanas and survives in a single manuscript. It includes unusual elements such as rope poses.
Vajroli mudra, the Vajroli Seal, is a practice in Hatha yoga which requires the yogi to preserve his semen, either by learning not to release it, or if released by drawing it up through his urethra from the vagina of "a woman devoted to the practice of yoga".
Mark Singleton is a scholar and practitioner of yoga. He studied yoga intensively in India, and became a qualified yoga teacher, until returning to England to study divinity and research the origins of modern postural yoga. His doctoral dissertation, which argued that posture-based forms of yoga represent a radical break from haṭha yoga tradition, with different goals, and an unprecedented emphasis on āsanas, was later published in book form as the widely-read Yoga Body.
Yoga Makaranda, meaning "Essence of Yoga", is a 1934 book on hatha yoga by the influential pioneer of yoga as exercise, Tirumalai Krishnamacharya. Most of the text is a description of 42 asanas accompanied by 95 photographs of Krishnamacharya and his students executing the poses. There is a brief account of practices other than asanas, which form just one of the eight limbs of classical yoga, that Krishnamacharya "did not instruct his students to practice".
The Path of Modern Yoga: The History of an Embodied Spiritual Practice is a 2016 history of the modern practice of postural yoga by the yoga scholar Elliott Goldberg. It focuses in detail on eleven pioneering figures of the transformation of yoga in the 20th century, including Yogendra, Kuvalayananda, Pant Pratinidhi, Krishnamacharya, B. K. S. Iyengar and Indra Devi.
Modern yoga as exercise has often been taught by women to classes consisting mainly of women. This continued a tradition of gendered physical activity dating back to the early 20th century, with the Harmonic Gymnastics of Genevieve Stebbins in the US and Mary Bagot Stack in Britain. One of the pioneers of modern yoga, Indra Devi, a pupil of Krishnamacharya, popularised yoga among American women using her celebrity Hollywood clients as a lever.
Srivatsa Ramaswami is a teacher of Vinyasa Krama yoga. He studied for 33 years under the "grandfather of modern yoga", Krishnamacharya. In India he teaches at Kalakshetra. He has run workshops in America at the Esalen Institute, the Himalayan Institute and many other centres. He is the author of four books on yoga.
Early modern yoga was the form of yoga created and presented to the Western world by Madame Blavatsky, Swami Vivekananda and others in the late 19th century. It embodied the period's distaste for yoga postures (asanas) as practised by Nath yogins by not mentioning them. As such it differed markedly from the prevailing yoga as exercise developed in the 20th century by Yogendra, Kuvalayananda, and Krishnamacharya, which was predominantly physical, consisting mainly or entirely of asanas.
Roots of Yoga is a 2017 book of commentary and translations from over 100 ancient and medieval yoga texts, mainly written in Sanskrit but including several other languages, many not previously published, about the origins of yoga including practices such as āsana, mantra, and meditation, by the scholar-practitioners James Mallinson and Mark Singleton.
The standing asanas are the yoga poses or asanas with one or both feet on the ground, and the body more or less upright. They are among the most distinctive features of modern yoga as exercise. Until the 20th century there were very few of these, the best example being Vrikshasana, Tree Pose. From the time of Krishnamacharya in Mysore, many standing poses have been created. Two major sources of these asanas have been identified: the exercise sequence Surya Namaskar ; and the gymnastics widely practised in India at the time, based on the prevailing physical culture.
The history of yoga in the United States begins in the 19th century, with the philosophers Ralph Waldo Emerson and Henry David Thoreau; Emerson's poem "Brahma" states the Hindu philosophy behind yoga. More widespread interest in yoga can be dated to the Hindu leader Vivekananda's visit from India in 1893; he presented yoga as a spiritual path without postures (asanas), very different from modern yoga as exercise. Two other early figures, however, the women's rights advocate Ida C. Craddock and the businessman and occultist Pierre Bernard, created their own interpretations of yoga, based on tantra and oriented to physical pleasure.
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.
