Firstly, there is the circle. In Taoist philosophy, a simple open circle, usually painted in such a way that the brush stroke does not fully connect or close it, represents "wuji" or the primordial state. "Wu" roughly translates to "nothing" or "emptiness" or simply "without" something. "Ji" is sometimes mistakenly translated as "energy" (perhaps confusing it with "jing" which will be discussed later) when it actually represents the polaric field, or presence of physical laws/limitations.
Ergo, "wuji" is "without limit" and "taiji" is "the extremity of limits" and here is where we run into further confusion. Most westerners have heard of "Tai Chi" and may be proud of themselves for knowing "well ACTUALLY it is 'tai chi CHUAN' and it is a fighting style, not just moving meditation" yet, again, oversimplification to the point of mistaken identity. More appropriately spelled "taijiquan" is, in fact, a martial art, can, in fact, be used quite adequately for real-world self defense, even against modern weapons -and it is ALSO moving meditation- I know, confusing for westerners... How can meditation be about fighting? How can practicing inner peace and mindfulness have anything to do with violence? Doesn't "tijiquan" mean "supreme ultimate fist" and represent the most powerful of all martial arts?
....Don't believe everything you read on the internet... Even this... Always question, always seek, always strive to delve deeper. Any system of philosophy, spirituality, or even martial arts should allow you to explore endlessly and never find the bottom. Remember that.
What I can tell you is only what I have come to know in the way I have come to know it. My explanation is not the ultimate explanation, but it is another way of looking at something that, in my opinion, is glossed over, particularly in Western culture, likely due in no small part to the fact that this culture is taught to value brute force and assertive strength over gentleness and passive strength -an imbalance which we shall address shortly- but first; What does "taiji" mean?
Okay, try and follow this... wu-ji is not just void or emptiness, but rather total potential for everything, only without any direction or form. Think of the universe before the "big bang" -that's wuji. Seriously and literally, that is what it is. There are philosophical implications, and martial ones too, such as the state of "no-mind" cultivated in some styles. In essence, wuji is ultimate potential, but it is also a state of rest. It is like standing at the crossroads of all time and space, only with no established directions, no laws of gravity or physics, no action by which to determine causality... all of that comes with tai-ji.
Think of the simple experiment you probably saw in science class as a kid; you place a magnet under a clear plastic sheet or table, then you sprinkle iron shavings on the surface and drum on it lightly until they start to form a pattern. That pattern marks out the magnetic field and shows the two distinct poles. Wuji would be the formlessness before establishing where the poles are, or, more accurately, it would be what you saw if the energy was there, but the poles were not... but since this is physical reality, and the state of taiji has already been established, there is no way for us to actually see that within the limits of this physical world.
So taiji is translated to "supreme ultimate" due, essentially, to laziness with expressing esoteric concepts. "Ji" is the essence of polarity, limit, law, or anything really which establishes, organizes, or classifies things in any way. "Wuji" is the absence of those things, accepting the presence and existence of all those things as yet to be organized, classified and established into their limiting categories. "Taiji" the the expression of the extremities of reach and ultimate scope of the same.
Yin and Yang are expressions of Ji, they are the essences of respective polarity in all things. Good and bad, light and dark, male and female, are extremely rudimentary expressions of yin and yang. In my opinion, the best words to describe yang are expansion, assertion and hardness. For yin- concentration, receptiveness, and softness. They apply, of course, to all things, but the point is they are less fixed and more flowing than is commonly understood or expressed. Think of them more as modes of transition rather than fixed states, in other words.
To try and illustrate this, let's go with something I hope everyone can understand. Taxonomically, humans are considered sexually dimorphic; meaning there are 2 biologically defined sexes as expressed by distinct sets of physical features. In this case, male is considered yang and female yin. However, it is now well established in psychology and neurology that human beings do not always typify their biological gender. Ergo, a male can have a lot more "yin" traits and females are fully capable of expressing "yang" energy, even above and beyond that of a "biological male". We are all made up of both, and express each in different ways and to greater and lesser degrees. There are even biological things that can manifest in a human being a combination of sexes to greater and lesser degrees, so the whole notion of trying to categorize everyone and everything into strictly binary categories is demonstrably absurd.
A better way to look at yin and yang, or the "taijitu" is in terms of cyclical flow. When you are awake, for instance, you are generally in yang mode. When you are sleeping, you are in a yin state. However, R.E.M sleep is the yang phase of the sleep cycle whereas N.R.E.M is the yin phase of this particular "yin" state. Likewise, when we are awake and doing physical labor or working out, for example, that is a yang state within our regular yang phase, but when we are spacing out in front of a TV or computer screen, that is a yin state in our yang phase. To take it even further, when you get "in the zone" of your workout, you have gone into a yin phase within your yang state within your yang phase of your daily cycle, and when you are crunching the numbers for an assignment which is coming up on its deadline, you are in a yang phase of a yin state in your yang phase of your daily cycle!
To call yang "good" and yin "bad" would be the same as saying we would all be healthier if we only inhaled and never exhaled because inhaling is yang and exhaling is yin. It is like saying the world would be a better place if the sun never set, because day is yang and night is yin. We need both. We are both. There is no existence without both, and neither is "good" or "evil" in itself. The only danger is excess or imbalance which manifests from giving too much energy to one or the other.
The point is yin and yang are never stagnant and THAT is the reason for the swirling design and presence of the dots within the black and white fields. They are not "a little bit of this in that" but more like a fractal of the empty wuji circle being reflected in endless repetition through the constant interplay of yin and yang which themselves never capture or reflect the true reality of wuji because, like a mirror, they can only ever show one side due to the limiting nature of physical reality.
In short, we are all constantly chasing our original nature. Not just humans, but all things. Just like rivers running to the sea or water evaporating and falling as rain, all of creation is constantly shifting between yin and yang- seeking expression of itself in different forms, always chasing that limitlessness that is a distant memory of wuji, though it is forever bound by taiji to be no more than half of what it could be, and infinitely less than what it was.
With the understanding of "wuji" we may also come to understand "wu wei" another commonly misinterpreted term in the western world...
As explained above, "wu" is the state of limitless potential in a formlessness state.
To understand "wei" let us begin by stating that martial arts and qigong practices are divided into "weidan" and "neidan" with neidan being those which are more internal and sedentary, like meditation, and weidan being those that are more active, such as physical exercise or the moving qigong most are more familiar with.
Westerners tend to translate "wu wei" as "doing nothing" or "non action" when in reality it is action by definition- being "wei"
Again, "wu" is not "nothing" but rather everything, just without definition. "Wei" is action or movement. Therefore "wu wei" is perhaps more clearly expressed as "action without attachment to outcome"
For me, wu wei is like surfing. You can't control when the wave will come, or where it will take you, you just wait until you feel the pull of the ocean and prepare to ride. You still have to kick your legs to climb the crest, but you have to let the wave lift you and drive you. It is a state of simultaneous surrender and gentle action. That's wu wei.
Martial arts like taijiquan and aikido are partially physical expressions of wu wei, so training in these arts can lead to a deeper understanding of the principle.
Now, on to inner alchemy. Here we will analyze both the Taoist and yogic models together and how they relate to one another.
It is no mistake that qigong is alternatively known as "taoist yoga." The fundamental principles that birthed the practice came over from India along with those of Buddhism, and even martial arts. India is home of one of the oldest civilizations on earth. Theories of medical qigong, acupuncture, and Chinese herbalism all originated there as well. This is not to say that all Chinese, and, later, Japanese arts (martial, healing, philosophical, etc) are not distinct creations of their own cultures, but rather than they all share a common root, or, put more poetically (and perhaps more correctly) they are like branches of a river, all flowing from a common source.
Inner alchemy is the study of the vital energies and the fields they generate (auras, for instance) along with the practice of cultivating those energies and altering those fields. It is the true goal of qigong. Even those who practice qigong for strictly physical purposes are still affecting the physical body through inner alchemy of the energetic body, though they may not be aware of this fact. Some (particularly in the west) willfully ignore it even, for fear moral conflict (some christians worry that such practices are demonic in nature) or reluctance to accept the existence of energies which science has yet to explain (though there are currently entire fields of sciences dedicated to just such endeavors- dark energy for example). One can, in fact (without looking too hard) find scientific papers and clinical studies which have proven legitimate and measurable results derived from practices like qigong, meditation, and yoga.
Some Taoists make inner alchemy an obsession. There are various methods of using breath, physical exercise, meditation, and even sex to build vital energies for the practice of inner alchemy. It all starts with jing, which is basic physical energy. Sexual energy is one of the more potent forms of jing and arousal without release is one of many methods used to build personal jing. There are also practices which involve establishing an energetic connection with a partner and cycling the energy between you both. This is what many westerners think of when they think about "tantra" though, in India, the true practice of tantra has many other facets and goes far deeper than just "sex magic" as it has been reduced to.
"Qi" and "chi" are one in the same, and the yogis would call it "prana" -all of them mean "breath" but it is more than the simple act of breathing, it is the essence of life which is absorbed and expressed through breathing. This is why inhaling and exhaling at the correct points is so vital to internal martial arts such as taiji and qigong. The entire practice of pranayama is dedicated to the breath, and may accurately be called "breath yoga."
Shen is probably the least discussed, and likely because it is the most difficult to describe. Shen is not simply "spiritual energy" it is the essence of Spirit itself. Shen is what makes everything come into being, but that which exists in physical form is only the vessel of jing. Shen is that which is before anything is-es... Shen is the state from whence all came, and to which all returns. We only touch shen like the clouds touch the sky before falling again as rain...
Kundalini is a totally separate energy, but one which can give us a stronger connection to Shen while simultaneously increasing our Jing (because of the microcosmic cycle, increasing any one of the "three treasures" ultimately increases the others). Skeptics balk at the notion of any such energies, particularly that of kundalini, yet anyone who goes to the process of awakening it can attest that it is undeniable.There is no stronger energy to be found within the human form than that of kundalini. It is palpable and its effects are profoundly felt in the physical body as well as the emotional, spiritual, mental, and social arenas. I have personally gone down this path, and, no, drugs are most certainly not necessary, but the effects it has on the consciousness may sometimes seem like it. As others before me have said, do not go lightly into this. Pushing too hard and awakening too fast can have serious side effects. Even done gently, and under the guidance of an experienced guru, kundalini awakening is going to cause considerable discomfort and force you to deal with things you would rather ignore. Nonetheless, it is probably the best way to access higher levels of inner alchemy.
Closing
So, when it comes to martial arts, qigong is the cultivation of vital energy, primarily through breath, but also through movement and meditation. NeiDan and WeiDan are the yin and yang aspects of qigong respectively, yet the whole essence and aim of the practice is to bring the two into harmony.
Tai Chi Chuan is not "supreme ultimate fist" but taijiquan- the fighting technique (quan) of extreme limits (taiji) or transitioning polarities. If you will look again at taijiquan as it is applied in combat this should become apparent- it blends with the opponent and reverses directions or pulls/pushes to extremes, shifting seamlessly between hardness and softness. The meditative and physical benefits come along with the practice, but it is, at its core, a fighting style first, and "exercise" second. Yoga, and qigong, on the other hand, are primarily spiritual exercises with physical results following in typical Eastern holistic fashion.
Through the study of inner alchemy, we come to a deeper understanding of the energies we have to work with, and through the practice of inner alchemy, we learn to apply and utilize these energies in various ways. It begins with refinement of self, then leads to unity with nature- wherein the illusion of "self" begins to fade, ultimately giving way to merging with others. It is through this ability to "blend" with another that the seemingly "supernatural" abilities of the practitioners emerge. Whether you use this for healing or fighting, the process is the same, which is why "inner peace" and gentleness are such a big part of the practices, regardless of their intent.
The value of these things in martial arts is beyond measure. The "three treasures" of jing, chi, and shen, are aptly named, for they can be used to help protect us from harm, heal injuries more effectively, and deliver much greater power in our execution of technique, not to mention increasing our overall vitality, focus, and general stability.
The young are prone to thinking only the fast, hard, and overtly violent has any value in the fighting arts. No matter how many fights you win, however, time and age are indomitable and will defeat all eventually. The "internal arts" are cherished by the mature martial artist who is more concerned with self preservation than with showing off. These practices are of value to everyone, and can enhance any practice, martial or otherwise, for young and old alike... but none can be convinced of this truth before they are ready to accept it. So I shall now leave you with verses from the immortal Lao Tzu-
"Out of The Tao came The One.
From The One, Two.
Out of Two, Three.
And out of The Three come the ten thousand things.
The ten thousand things carry yin on their backs and clutch yang to their breast.
Harmony is achieved by combining these forces in the two breaths.
People loath to be 'lonely,' 'needy,' or 'worthless,'
Yet this is how kings and lords describe themselves.
For one gains by losing
And loses by gaining.
The maxims that others use in their teaching I too will use in mine. Show me a man of violence that came to a good end, and I will take him for my teacher."
(Wuji is "The One" yin and yang are "Two" and the taijitu is the constant interplay of these principles or "Three" and "the ten-thousand things" is the expression Lao Tzu used to describe worldly creation. All things contain yin and yang, and we harmonize these forces "in the two breaths" or qigong and inner alchemy. To be humble is to be exalted, and spiritual power is accumulated not by taking, but by giving. To live for violence is self-destructive, but the traveler on the path of peace is no stranger to violence, they simply do not seek it. Martial arts should always be holistic systems which teach peace and war, physical development and spiritual development, healing and hurting when each is called for. Seek BALANCE, my friends... balance in all things...)
Addendum; Regarding modern, Western, science and the legitimacy of the three modes of energy-
Jing is the Chinese esoteric name for what science now measures in things like calories and newtons. In Chinese esoteric philosophy, jing become chi which becomes shen. "Chi" is sometimes translated as "breath" and it is the "breath" that is used as the primary vehicle for transporting "chi" throughout the body in exercises like qigong. It is also "breath control" that is used in many martial arts as a means of maximizing force of a technique. THAT is textbook chi when you actually understand what it literally means in the context that the masters who put it into their martial arts meant it. "Shen" is the one we are only beginning to understand scientifically, but it is related to the bio-electric, bio-magnetic, and bio-chemical signals sent and received by our bodies as a sort of radiant field or "aura" if you will. These too are very real and measurable phenomena. "Chi masters" or advanced practitioners of qigong have been recorded under controlled laboratory conditions generating extreme low frequency sound waves by "channeling chi" as they would when treating a patient. These are the same kinds of frequencies with which elephant communicate because they are capable of traveling great distances and even penetrating solid objects without losing too much of their integrity- just the kind of vehicle you would need to, say, penetrate deep into body tissues...
