Stretching and breathing are just two aspects of yoga

BKS Iyengar emphasized yoga's physical aspect

The guru’s 1966 book “Light On Yoga” included detailed instructions for over 200 postures, presenting a version of yoga that emphasized it as a form of exercise with controlled breathing, believing that its physicality was the key to unlocking its spirituality. The book was the first mass-market manual to show the poses, furthering the Western impression that yoga was primarily about exercise.

Practices and beliefs from Hinduism, Buddhism, and Jainism influenced yoga

Yoga scholars Mark Singleton and James Mallinson’s study, “Roots of Yoga,” collects over 100 core texts on the subject. They found that many different ethnicities and religions practiced yoga in antiquity; Singleton says that the practice was a “floating technology between various religious systems.”

Yoga dates back to about 1500 BCE

The earliest known mention of the word is in the Rig Veda, one of the four canonical Hindu texts. Rishis, or sages, then documented its evolution in the Upanishads, the Hindu scriptures. Much of the modern understanding of Yoga comes from “Yoga Sutras of Patañjali,” which outlines the practice’s eight elements, including physical postures and breathwork.

How yoga philosophy inspired Thoreau

In the 19th century, yogis traveling in America emphasized the practice as a philosophical one rather than a purely physical act. Like many Americans at the time, including his friend Ralph Waldo Emerson, Thoreau was intrigued by yoga's mysticism, once writing, "I cannot read a single word of the Hindoos without being elevated."

Some parents have objected to yoga in schools

Why yoga teachers are dissecting cadavers

Thousands of fitness professionals are choosing to attend cadaver workshops to improve their understanding of anatomy and their teaching abilities. Though 3D virtual models give students a fresh way to explore the human body, medical students say experiencing the intricacies in person is far more instructive. As fitness professionals increase their understanding of the muscular and skeletal systems, their movement cues and instructions evolve in tandem.

Bikram Choudhury's abuse dismantled his yoga empire

The guru popularized a form of hot yoga that followed a 26-point script. In the process, he became incredibly wealthy and ostentatious. In the early 2010s, formal accusations against him began, ranging from harassment to rape. He fled the US in 2017 to avoid paying his former lawyer a sexual harassment settlement. In the US, the "Bikram yoga" style has been divorced from its namesake but is still practiced, often as "hot yoga." Bikram still teaches yoga outside the country.

Winter Olympic sports highlight various laws and principles of physics

Figure skaters leverage the conservation of angular momentum during spins by tightening their bodies, and the skintight suits used in ski jumping help reduce drag. Centripetal force allows speedskaters to make tight turns, while friction on skis helps ski mountaineers climb slopes. No action can violate the conservation of energy.

The universe expands by stretching space itself, not into anything beyond it

Thanks to Einstein’s relativity and Hubble’s observations, scientists understand that space stretches, like rising bread dough between raisins, with no "outside" to expand into. Some theories suggest our universe might be just one "bubble" in a vast multiverse, possibly floating on a higher-dimensional surface called a brane.

The art of classical rhetoric

Ancient orators snapped human communication in two: the open palm of persuasive rhetoric versus the closed fist of evidence-heavy dialectic. The former seeks to convince the many via one's speech, while the latter seeks the truth in an argument. In ancient Rome, rhetoric had five "canons": invention, arrangement, style, memorization, and delivery. Loading the rhetorical canons in order was meant to help orators craft an effective and impactful speech.
