“Every body continues in its state of rest, or uniform motion in a right line, unless compelled to change that state by forces impressed upon it.”

– “Law 1” quoted from “Axioms, or Laws of Motion” in Philosophiæ Naturalis Principia Mathematica by Sir Isaac Newton

NOTE: Some editions use the term “straight line.”

Take a moment to relax, maybe place your hand(s) on your belly, and observe what happens if nothing gets in the way. Notice how your tension-free belly rises and falls as the breath enters and leaves the body. Notice how the “force” of the breath, which is a symbol of our life and a symbol of our spirit, is an agent of change – physically, mentally, emotionally, and even energetically.

You can use your breath, forcefully, to break up and/or release tension. Similarly, lengthening the breath and observing the breath (which can all be described as prāņāyāma) change things when we are practicing on the mat. The way we breathe and the awareness of our breath can also be an agent of change off the mat. We just have to pay attention and stay focused to things that are naturally occurring.

However, paying attention, staying focused, and even breathing deeply in and breathing deeply out can be challenging in certain situations… especially situations involving challenging people… rigid bodies, if you will.

“I most gladly embrace your proposal of a private correspondence. What’s done before many witnesses is seldom without some further concerns than that for truth; but what passes between friends in private, usually deserves the name of consultation rather than contention; and so I hope it will prove between you and me….

But in the mean time, you defer too much to my ability in searching into this subject. What Descartes did was a good step. You have added much several ways, and especially in considering the colours of thin plates. If I have seen farther, it is by standing on the shoulders of giants.”

– quoted from a letter marked “Cambridge, February 5, 1675-76” from Sir Isaac Newton to Dr. Robert Hooke, as published in Memoirs of the Life, Writings, and Discoveries of Sir Isaac Newton by David Brewster

Sir Isaac Newton was just a 43-year old “natural philosopher” when he published the first edition of his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) today in 1687. The treatise included definitions of terms, his laws of motion, and a law of universal gravitation. It was partially based on Sir Isaac Newton’s own observations of the natural world and partially based on the theories, definitions, and observations of others. Those others, which Sir Isaac Newton referred to as “giants,” included Galileo Galilei and Johannes Kepler – whose laws of planetary motion were themselves modifications of the observations and heliocentric theory of Nicolaus Copernicus, yet another giant.

All of the aforementioned natural philosophers – or scientists, as we now call people who study matter and the mechanics of matter in space and time (i.e., physics), started with phenomena that was naturally occurring; could be observe in nature; and could be duplicated on some level. Then they went deeper… or farther, depending on your perspective. For Sir Isaac Newton, going deeper and farther meant having discussions with some his peers and even with some people who were skeptical of his work. He even had an ongoing correspondence with one of his master teachers and precious jewels – someone we might refer to as a “rigid body.”

1. An object at rest remains at rest, and object in motion remains in motion (at the same speed and in the same direction, unless acted upon by an unbalanced force).

2. The acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.

3. For every action there is an equal and opposite reaction.

– Sir Isaac Newton’s Laws of Motion

In physics, a “rigid body” (or “rigid object”) is a solid collection of matter that (a) does not change in size or shape or (b) changes at such a miniscule level that it is not perceptible. In quantum mechanics, the focus is on a collection of points – which, on a very rudimentary level, takes us back to the original definition. Focusing on a collection of points means highlighting a consistent distance between points that allows for the external appearance of stillness. In Albert Einstein’s theory of special relativity, nothing is absolutely rigid and, therefore, something is only considered “rigid” if it is not moving at the speed of light. This latter understanding means that the issue of something (or someone) being rigid becomes an issue of perception (and relativity).

Just like with the laws of motion – and, in particular with “The Law of Inertia” (i.e., the first law), the idea of a “rigid body” is physical science that can be observed on and off the mat. We can observe it in the way we move – physically, mentally, emotionally, and even energetically. We can observe it in the way holding a pose is perceived as “stillness,” even though there is movement and change. If we just go a little deeper, we start to notice cause-and-effect and how the laws of motion are also the laws of karma. For example, if we do something nice for someone, they can do something equally nice for someone else. When we really pay attention, we start to notice the the ways things (and people) change over time – even when they appear not to change.

“Every relationship you develop, from casual to intimate, helps you become more conscious. No union is without spiritual value.”

– quoted from “Morning Visual Meditation” (Chakra 2) by Caroline Myss

According to Eastern philosophies, like Yoga and Buddhism, everything is an opportunity for practice. In fact, the Yoga Sūtras include many reminders that everything is an opportunity to learn more about ourselves, about our true nature, and about the universe. Yoga Sūtra 2.18 specifically states that everything is an opportunity to liberate ourselves. So, what do we do when we interact with someone who seems resistant to change and/or to seeing things from different perspectives?

We could view them as master teachers, precious jewels, and/or rigid bodies.

Master teachers give us a master classes in ourselves. Precious jewels – like a grain of sand or salt in the shell of an oyster, clam, or other shelled mollusks – can be that irritating source of something we eventually view as valuable. It’s all a matter of perspective. One way to cultivate this perspective is by viewing another person as our reflection. If we are interacting with someone who appears to be “hooked,” we might recognize that we are (possibly) also “hooked” – which is the first step in getting “unhooked.” Similarly, if we feel like we are banging our head up against a brick wall and start seeing someone as a “rigid body,” we might ask ourselves: What/where is the change we are not perceiving?

Remember, according to Albert Einstein’s theory of relativity, nothing is absolutely rigid. Ergo, change is always happening… somewhere.

It is happening inside the mind-body of people we may consider rigid; it is also happening inside of our own mind-body. We are not responsible for the change that is happening (or not happening) inside of someone else. However, when we notice the possibility of change inside of ourselves, the question then becomes, do you resist the change or embrace the change? Answering that question does not mean that we give up on our ideas or conform to the way someone else thinks. No, it means going deeper and farther… like Sir Isaac Newton.

“‘But this I immediately discovered in him,’ adds [Dr. Henry Pemberton*], still further, ‘which at once both surprised and charmed me. Neither his extreme great age, nor his universal reputation had rendered him stiff in opinion, or in any degree elated. Of this I had occasion to have almost daily experience. The remarks I continually sent him by letters on his Principia, were received with the utmost goodness. These were so far from being anyways displeasing to him, that, on the contrary, it occasioned him to speak many kind things of me to my friends, and to honour me with a public testimony of his good opinion.’ A modesty, openness, and generosity, peculiar to the noble and comprehensive spirit of Newton. ‘Full of wisdom and perfect in beauty,’ yet not lifted up by pride nor corrupted by ambition. None, however, knew so well as himself the stupendousness of his discoveries in comparison with all that had been previously achieved; and none realized so thoroughly as himself the littleness thereof in comparison with the vast region still unexplored.”

Chittenden, as published in Newton’s Principia: The Mathematical Principles of Natural Philosophy; To which is added, Newton’s System of the World by Isaac Newton, translated into English by Andrew Motte (first American edition; New York: published [1848] Daniel Adee, c1846) 

*NOTE: Dr. Henry Pemberton edited the third edition of the Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy). 

Up until the twentieth century (and the publication of Albert Einstein’s theory of relativity), the Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) was the starting point for many scientist as they observed and explored the natural movement of the world. In many ways, that first edition was also Sir Isaac Newton’s starting point.

After sharing his ideas and theories, Sir Isaac Newton went back, reviewed his work, and published a second edition of the Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), with annotation and corrections, in 1713. He published a third edition in 1726. Eventually, he was recognized as one of the world’s greatest mathematicians and physicists and his Principia became the foundation for classical mechanics – one of the cornerstones of modern physics.

Eventually, Sir Isaac Newton became one of the “giants.”

“A short time before his death he uttered this memorable sentiment: ‘I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, while the great ocean of truth lay all undiscovered before me.’ How few ever reach the shore even, much less find ‘a smoother pebble or a prettier shell!’”
