Haṭha yoga is a branch of yoga. The Sanskrit word हठ haṭha literally means "force" and thus alludes to a system of physical techniques.
An asana 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.
Tirumalai Krishnamacharya was an Indian yoga teacher, ayurvedic healer and scholar. He is seen as one of the most important gurus of modern yoga, and is often called "the father of modern yoga" for his wide influence on the development of postural yoga. Like earlier pioneers influenced by physical culture such as Yogendra and Kuvalayananda, he contributed to the revival of hatha yoga.
Uttanasana or Standing Forward Bend, with variants such as Padahastasana where the toes are grasped, is a standing forward bending asana in modern yoga as exercise.
Siddhasana or Accomplished Pose, is an ancient seated asana in hatha yoga and modern yoga as exercise suitable for meditation. The names Muktasana and Burmese position are sometimes given to the same pose, sometimes to an easier variant, Ardha Siddhasana.
Virasana or Hero Pose is a kneeling asana in modern yoga as exercise. Medieval hatha yoga texts describe a cross-legged meditation asana under the same name. Supta Virasana is the reclining form of the pose; it provides a stronger stretch.
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 America 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.
Gorakshasana is a seated asana in hatha yoga. It has been used for meditation and in tantric practice.
Vajroli mudra, the Vajroli Seal, is a practice in Hatha yoga which requires the yogin 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".
Yoga Body: The Origins of Modern Posture Practice is a 2010 book on yoga as exercise by the yoga scholar Mark Singleton. It is based on his PhD thesis, and argues that the yoga known worldwide is, in large part, a radical break from hatha yoga tradition, with different goals, and an unprecedented emphasis on asanas, many of them acquired in the 20th century. By the 19th century, the book explains, asanas and their ascetic practitioners were despised, and the yoga that Vivekananda brought to the West in the 1890s was asana-free. Yet, from the 1920s, an asana-based yoga emerged, with an emphasis on its health benefits, and flowing sequences (vinyasas) adapted from the gymnastics of the physical culture movement. This was encouraged by Indian nationalism, with the desire to present an image of health and strength.
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.
Seetharaman Sundaram was a lawyer and pioneer of yoga as exercise, often known as Yogacharya Sundaram, and the first person to publish a handbook of yoga asanas in English, his 1928 Yogic Physical Culture. This was also the first yoga book to be illustrated with photographs. He travelled India with the bodybuilder K. V. Iyer, helping to popularise the new blend of hatha yoga and physical culture.
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.
Yoga in the United States has a long history, foreshadowed in the 19th century by the philosophers Ralph Waldo Emerson, whose poem "Brahma" is a statement of the Hindu philosophy behind yoga, and Henry David Thoreau, and starting in earnest with 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.
The science of yoga is the scientific basis of modern yoga as exercise in human sciences such as anatomy, physiology, and psychology. Yoga's effects are to some extent shared with other forms of exercise, though it differs in the amount of stretching involved, and because of its frequent use of long holds and relaxation, in its ability to reduce stress. Yoga is here treated separately from meditation, which has effects of its own, though yoga and meditation are combined in some schools of yoga.
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.
The Story of Yoga: From Ancient India to the Modern West is a cultural history of yoga by Alistair Shearer, published by Hurst in 2020. It narrates how an ancient spiritual practice in India became a global method of exercise, often with no spiritual content, by way of diverse movements including Indian nationalism, the Theosophical Society, Swami Vivekananda's coming to the west, self-publicising western yogis, Indian muscle builders, Krishnamacharya's practice in Mysore, and pioneering teachers like B. K. S. Iyengar.
