Consider, for example, the following cycle of nature: yin, the ever-abiding sea, receives yang, the sun’s rays, whence arises yang as water vapor (clouds) to dwell within yin, the sky. The sky gives birth to yang, the rain, received by yin, the earth, which supports yang as flowing river seeking reunion with a boundless sea of yin. This constant arising of yang within yin and yin inherent in yang is shown by the contrasting “eyes” within the stylized yin-form and yang-form, which, together, in-form the circular boundary of the symbol. Black/yin has an ever expanding point of white, appearing in the position of an eye, while the converse is true of the white/yang form. Here we have the ingenious artistic rendering, possessing the quality of a figure/ground relationship which “ping-pongs” the observer’s eye to and fro within the contrast between black and white, serving to imbue the symbol with a seeming dynamism of movement. Where yang is not, there is yin; where yin is not, there is yang. The relationship is inseparably interdependent, for neither exists except as its own opposite give it form. In prototypical conceptual terms this is how the manifest universe ceaselessly becomes and passes away in a constant natural flow: the mutual transformation of opposites.
While yin and yang represent any conceivable pair of opposite at all levels, the unifying reality of the symbol is a totality which supports and transcends all opposites: the circle. Consider an ancient symbol of infinity (and the universe), the Ouroborous—the serpent which consumes its own tail to nourish its own growth. Or, consider the face and obverse of a coin which is transcended and subsumed by the wholeness of the coin itself. Yin and yang have no independent existence, for one is implicit in the other as dual aspects of a encompassing unity. They exist independently only as mental interpretations (via the inherent cognizing function of the mind), as seemingly isolated points in a continuum which are simultaneously both and neither of its extremes (for instance, a baton, having two ends, is not deemed to be exclusively one end or the other, nor both, taken additively, but their unity). This inherent contrast of opposites is represented graphically in the yin-yang symbol by the black and white pair fitting together to form the circle that circumscribes them. The subsuming circle, with its partial aspects, yin and yang, is one symbol for the Chinese TAO. Variously translated as “way” or “suchness of manifestation”, it is THE NAMELESS. The Original-Reality-Beyond-Concept; the Self-Existent Absolute; Consciousness Without An Object (or Subject): everywhere and nowhere, eternal yet instantly vanishing, immanent, eminent and everywhere imminent—in short, omnitaneous reality.
Bearing the foregoing development of yin and yang in mind, let us now proceed to another application of its elucidation. Let us assign for the logo’s black/white contrast, the ultimate of opposites for humans: consciousness (white) and all objects of consciousness (black), i.e., the manifest universe. Thus the self-in-consciousness, or conscious-center-of-awareness, the “I”, in its life-long outward quest, forever encounters its absolute opposite, the surface of an apparently infinitely extended cosmos of objects apparently outside and impenetrable to it. Can you see then, that all objects of consciousness actually in-form consciousness, i.e., give it form by delimiting its borders (like a flashlight beam is limited or obstructed by what it shines upon). Conversely, all objects of consciousness are equally in-formed by the consciousness of them. Neither consciousness nor its objects exist independently, as each defines the other—renders it manifest—just like a flashlight beam is undetectable without an intervening atmospheric obscuration of, say, fog or smoke, or other objects undetectable without the illumination of the flashlight beam. The yin-yang figure visually portrays this idea: the quintessential nature of the universe is Pure Consciousness, or Consciousness-Without-An-Object-and-Without a Subject (CWOWS). Subjective consciousness—man’s consciousness—versus all objects of consciousness are the dual relative aspects subsumed and transcended by unitary, self-existent CWOWS, just as yin and yang are subsumed and bounded by the circle in the TAO symbol. Self-awareness and its antithetical objects-of-perception literally create the universe as follows: subject perceives object and object in-forms subject. This means that object and subject are not incommensurate things, they are opposing aspects of a unifying CWOWS which is beyond yet within them. Subject consciousness is the perceiving of objects and objects literally are their perception in consciousness. “One hand washes the other”. There can be no movie without the film obstructing the projector light…and, beyond that, nothing whatsoever without the cinema screen itself “hidden” by the form, color and action of the film itself.
We see then, the so-called “inner world” of consciousness and the “outer world” of space-filled-with-things to be really a continuum like the face and obverse of a coin. An intrinsic condition of human sentience is its ongoing awareness (to greater or lesser degree) of its own awareness (“apperception”). In this it makes its own consciousness an object of perception. As we shall see, this has some significant implications. Consider that where consciousness perceives itself, there is nothing to perceive, since it has become an object of consciousness and therefore assumes its antipodal form, unconscious objects--voids (i.e., it obstructs itself by denying itself). This is an impossible, lifting oneself by one's bootstraps-type operation, presenting a paradox: consciousness, in attempting to perceive itself, perceives non-consciousness, i.e., effectively hides itself. It is like a searchlight trying to shine upon itself, and in its pivoting about, illuminating everything but itself. This is the central dynamic and enigma of the boundary between the known and unknowable: subject-consciousness, in seeking itself, ipso facto finds the universe instead. Perception of the cosmos is the creation of the cosmos. The ‘physical’ universe and consciousness are one.
Consciousness can be likened to a disembodied eye (in a land where mirrors are non-existent). Such an eye cannot see itself for it is that which does the seeing—the functioning of sight. As is true of all the senses (including the mind, as it is a vehicle and synthesis of them), all that the eye beholds, it very literally is, since all objects of sight cannot be separate from the agency that sees them. When the eye looks to see itself, it can behold only the absence of itself; and it is this absence that is the foundation of all the objects of sight—the absence that allows and structures their existence. The perfection of functioning for eyes is not being in the way of (i.e., being absent to) what it sees. It is absolutely behind everything so all things can be in-front-for-sight. To expand the metaphor somewhat: imagine spinning around trying to glimpse the back of your own head and forever seeing only that which is the perfect absence of it, i.e., what, of necessity by design, is always 180 degrees from the back of your head. But, strangely, this is the only way you can see the back of your own head, for it is connected, indeed inseparable, via its own absence, to all you do see. This is the mind-blowing way that emptiness (absence) and fullness (form) are united. It is described as follows, in the Heart Sutra:
Here, O Sariputra, Form is Emptiness and the very Emptiness is Form;
Emptiness does not differ from Form; Form does not differ from Emptiness.
Whatever is Form—that is Emptiness. Whatever is Emptiness—that is Form.
The same is true of Feelings, Perceptions, Impulses and Consciousness.
Here is the most profound and most subtle but challenging endeavor of all mentation. Paradox confounds the mind—runs it into an alley and sets it against itself. For, designed to project outwards, to objectify the cosmos by isolating itself from its partner in creation, the mind sees Fullness in its own Absence…yet knows it not.
All objects of consciousness are absences thereof, yet partaking of form as if independent, exotic “things-out-there” and vouchsafed by an incommensurate, immaterial, conscious perception. In other words, the tail wags the dog.
