When we think about defining terms, our first impulse is often to consult a dictionary. Actually, this is a pretty helpful exercise where yoga is concerned, though not because it helps us arrive at anything like a simple or even useable definition. Here is the first half of the entry for âyogaâ in the Monier-Williams Sanskrit-English Dictionary, which has served as an essential reference for scholars of South Asia in the English-speaking world since it was first published in 1850:
Yoga:
The act of yoking, joining, attaching, harnessing, putting to (of horses); a yoke, team, vehicle, conveyance; employment, use, application, performance; equipping or arraying (of an army); fixing (of an arrow on the bow-string); putting on (of armour); a remedy, cure; a means, expedient, device, way, manner, method; a supernatural means, charm, incantation, magical art; a trick, stratagem, fraud; undertaking, business; acquisition, gain, profit, wealth, property; occasion, opportunity; any junction, union, combination, contact; to agree, consent, acquiesce in anything; mixing of various materials, mixture; partaking of, possessing; connection, relation; in consequence of, on account of, by reason of, according to; putting together, arrangement, disposition, regular succession; fitting together, fitness, propriety, suitability; exertion, endeavour, zeal, diligence, industry, care, attention; application or concentration of the thought, abstract contemplation, meditation, (esp.) self-concentration, abstract meditation and mental abstraction practised as a system (as taught by Patañjali and called the Yoga philosophy); [âŠ]
Monier-Williams does then go on to list several more âsectarianâ meanings of the word, belonging to many of the groups weâll survey in the course of this book, like the âthe union of the individual soul with the universal soulâ (the PÄĆupatas), âthe union of soul with matterâ (SÄáč
khya), and âcontact or mixing with the outer worldâ (the Jains). The convention here, like in many dictionaries, is to list the most common usages for a word first, and then move towards the increasingly obscure.1 So, as we can see, the most common meanings of âyogaâ actually have very little to do with the kind of practices, be they physical or spiritual or both, that weâll be discussing in this book. Indeed, if there is a connection to such generic usages to be found here, that connection is first and foremost figurative and metaphorical.
The fact of the matter is that âyogaâ is a very basic and generic kind of word. It derives from the Sanskrit root âyuj, which means something like âto connect,â âto join,â or, in a more applied sense, âto yoke.â In fact, our English word âyokeâ is a true cognateâmeaning that it derives from the same common linguistic root. And so, if we want to understand why the meanings of yoga, even the more technical ones, have been historically so diverse, a helpful starting point is precisely to think about the basic and generic nature of the word itself and how this might lend itself to all sorts of imaginative applications. The simplest tools are often the ones that can be used for the greatest variety of purposes.
English speakers donât tend to use âyokeâ as robustly but, as yoga scholar David Gordon White has suggested, perhaps we could instead think of a word like ârig.â2 Potentially functioning as either a noun or a verb, ârigâ has a similar kind of range of meaning to âyoga.â A rig can be a structure or a device, as in a âsailing rigâ or an âoil rig.â It can also be the act of assembling this structure, or really of assembling anything, as in âto rig the sailboatâ or âto rig up a tent.â You can even ârig an election,â similar to the use of âyogaâ to mean an illusion or trick.
So, imagine that, a few millennia ago, there emerged a spiritual practice called âriggingâ based on, letâs say, the metaphorical likening of the complex arrangement of ropes, cables, and chains necessary to hold together the components of a sailing vessel to the complex and systematic self-discipline needed to achieve a particular spiritual state. Fast-forward two and a half millennia or so and, on the other side of the world, now you have people heading into fitness studios to get themselves ârigged up.â That, essentially, is the story of âyoga.â
But of course this is still all very general. Even if weâre talking specifically about spiritual practices, these still tend to be pretty diverse. Throughout human history, people have engaged in all sorts of spiritual disciplines to achieve all sorts of goals, depending on how it is that they imagine the universe to operate, what they imagine the highest purpose of this universe to be, and so on. If yoga is about âyoking,â then we might start by looking at the vast variety of things that people might have historically wanted to yoke or bring together in the context of South Asian worldviews. There we find that âyogaâ describes the union of the individual soul with the absolute, but also to the union of one personâs consciousness and will with that of another, or else (perhaps most literally) to the union of warriors to the celestial chariots that were believed to carry them into the afterlife after a particularly glorious death on the field of battle. Add to this the fact that, as weâll discuss imminently, there are things that we might want to call âyogaâ in hindsightâmaybe because they shared some crucial commonality with later yoga practices or eventually evolved into things that are called âyogaââbut that were not called this at the time. In other words, pinning down the history of yoga is very messy.
In the end, thereâs a two-fold trick to wrapping your head around yoga (or anything else historical). The first step is to realize that people are people. Meaning, regardless of time and place, human society is complicated. Itâs colored by diversity and disagreements, social and political and above all economic interests, power grabs, noble intentions, and the vast distance between ideals and their lived realities. From this perspective, to imagine that there was a time in the golden past when everyone sat down in perfect isolation from the hustle-and-bustle of daily life, read a single text (say, the Yoga SĆ«tras), understood it perfectly, practiced it to the letter, and mutually agreed to call this âyogaââwell, it just isnât very realistic.
The second step, though, is to recognize that people can and do have radically different worldviews. Especially when separated by time and place. Think about it: a few hundred years ago, you could have lived your life thinking that the sun revolved around the earth. This would have been perfectly rational and supported by the dayâs most advanced science. So, from this perspective, to project our modern understanding of bodies, minds, and everything in between onto pre-modern yoga texts and their practitioners isnât very realistic either. If weâre going to understand yoga practices, we have to think about them in the context of their culture and their time. This includes recognizing variability and change, as well as letting go of the notion that ancient practices are somehow more authentic or that modern practices are somehow more rational.
Given all of this, it should come as no surprise that not only has there never been a universally agreed upon definition of yoga, but yoga practices (the entire spectrum of them) have continuously changed and evolved in tandem with the culture around them. So, when we attempt to define yoga, we can take one of two fundamental approaches. We can really double down on the historically and contextually variable meanings of yoga and try to trace the intricate relationships between these. How do groups define the methods and goals of yoga differently based on their specific understanding of the world? How do they interact and respond to one another based on these different definitions and understandings? How do the usages and applications of yoga change through these interactions? Otherwise, we can look for common trends. What, in the end, seems to stay more or less constant across time and space and context? Is there some shared story or set of assumptions that tends to characterize âyogaâ wherever it pops up? For our part, weâll be doing some of both.
Before we dive deeper into various ways or defining yoga, though, one caveat: we wonât really be focusing on postural practice. That is, the idea of moving the body or putting it into different poses, with which the casual Western observer might be most familiar. After all, the idea of moving the body is not in and of itself very interesting. We do this all the time. Whatâs interesting is why we move the body in specific ways, and in order to get at the âwhyâ we have to (for instance) consider whatâs going on inside the body. What is putting the body in one pose or another, moving it this way or that supposed to be doing? And towards what purpose? In other words, if we want to understand the specifics of yoga practice, postural or otherwise, itâs these framing questions that we have to answer first.
To this end, letâs look at some of the traditional ways in which South Asian texts have talked about and defined yoga. From this, weâll move to examine a few modern scholarly definitions. And finally, at the end of the chapter, weâll propose a few helpful frameworks of our own.
Traditional definitions
Historically, Indian sources have tended to use the word âyogaâ to designate the goal of a certain practice, rather than the practice itself. That is, traditionally, one doesnât âdo yoga,â one achieves yoga by doing some other designated thing or set of things. Sometimes, of course, these two ideas can overlap, insofar as the state of yoga is described as the successful accomplishment of some actionable goal.
One of the first places the term âyogaâ becomes linked with a body of mental (meditation) and physical (asceticism) practices is in the early UpaniáčŁads, a set of mystical texts mostly composed between the 5th century BCE and the 1st century CE. The Kaáčha UpaniáčŁad (6.11), for instance, tells us: âThey consider yoga to be firm restraint of the senses. Then one becomes undistracted, for yoga is the arising and the passing away.â3 The same text famously compares the human mind-body organism to a chariot, wherein the Self is the rider, driven by an intellect, which grasps the reigns of the mind yoked to the senses or horses. So, in this case, we can very clearly see the connection between âyogaâ in its more generic sense as hitching up a chariot and its more figurative sense as restraining the senses. A well-yoked mind is a yoga.
Somewhat similarly, the Yoga SĆ«tras of Patañjali, a famous compilation of aphoristic verses probably dated to sometime between 325 and 425 CE, tells us that âYoga is the suppression of the fluctuations of the mindâ (yogaĆ-citta-váčttinirodhaáž„, 1.2). The traditional commentary for the textâs opening verse also equates yoga with the state of samÄdhi or completion, wherein the mind is single-pointed in such a way as to reveal reality in true nature, thereby cutting off psychological afflictions, loosening the bonds of karma, and creating the proper conditions for the full stilling of cognition.4 This definition, like the previous, focuses on the mechanics of the mind, or its internal rigging, so to speak.
Other definitions treat yoga as a way of connecting some aspect of oneself to something else. For example, the PañcÄrtha BhÄáčŁya, a 4th-century CE commentary on the earlier PÄĆupata SĆ«tra, specifies that âin this system, yoga is the union of the self and the Lordâ (1.1.43).5 The Lord, in this case, is God and specifically Ćiva. Yoga, then, is the state of being connected to Ćiva. Notably, the PÄĆupatas, to whose tradition this text b...
