Structural Organization & Internal Arts

“Nature does not hurry and yet everything is accomplished” – Lao Tze

In the internal arts we often describe “Zhan Zhuang”, or standing practice, as “standing like a tree.” At first this seems to be a simple metaphor, encouraging the practitioner to become rooted, stable, and patient. Yet the longer I have practiced the internal arts, studied Chinese medicine, and worked with patients recovering from injury and surgery, the more I have come to believe that the comparison is far more profound.

Perhaps the tree is not merely an image but a model of organization. Trees and human beings are separated by millions of years of evolution and vastly different forms of life, yet both face the same fundamental challenge: how do you move nutrients, water, information, and chemical messengers throughout an entire organism while continuously adapting to an ever-changing environment?

Nature’s answer is not force but structural organization. Throughout nature we see the same principle repeated at every scale. Rivers organize themselves into branching watersheds. Root systems spread through the soil in search of moisture and nutrients. Fungi create vast underground communication networks that connect entire forests. Trees develop branching canopies that maximize sunlight while minimizing resistance to wind. Living systems do not rely upon isolated parts. Instead, they create interconnected networks, matrices, through which energy, fluids, nutrients, and information can move efficiently.

A healthy forest is far more than a collection of individual trees. Beneath the soil, roots intertwine with fungal networks, exchanging nutrients and chemical signals. Above the ground, the canopy regulates light, temperature, humidity, and airflow. Every part contributes to the health of the whole. Structural organization is not unique to forests, it appears to be one of nature’s fundamental strategies for sustaining life.

A closer look at the anatomy of a tree reveals a remarkably simple principle. Every part has a unique function, yet no part functions independently. The outer bark protects the tree from the environment, while the inner bark distributes the sugars produced by the leaves throughout the tree. Between them lies the cambium, a thin layer that continually generates new growth. Beneath it, the sapwood transports water and minerals from the roots to the branches, while the heartwood provides the structural support that allows the tree to withstand gravity, weather, and time. High above, the leaves harvest sunlight, produce nourishment through photosynthesis and release hormones that help regulate future growth (U.S. Department of Agriculture, 2026).

No single part of the tree is responsible for its health. Protection, communication, fluid transport, growth, and structural support all depend upon one another. The tree survives not because one system is dominant, but because every system is organized into a unified whole.

This may be the most important lesson the tree offers us. Nature does not separate structure from function, or communication from circulation. They are inseparable. Organization allows every part to support every other part, creating a living system that is both remarkably resilient and efficient. This principle is not only fundamental to the life of a tree but to the organization of the human body as well.

Even the body’s fluids exist as an integrated network rather than isolated compartments; blood delivers oxygen and nutrients, lymph returns proteins, immune cells, and interstitial fluid to the circulation. Cerebrospinal fluid surrounds and nourishes the central nervous system. Interstitial fluid bathes every cell. Intracellular water provides the environment in which nearly every biochemical process occurs. The body is not simply filled with water, it is organized through its dynamic relationships with it. Gerald Pollack discusses this structural organization in depth in his book The Fourth Phase of Water (Pollack, 2013).

Just as the tree depends upon an organized vascular system to sustain life, the human body depends upon the harmonious movement of its many fluids through an equally sophisticated network of structures. Movement alone is not enough. It is structurally organized movement that sustains health. One of the greatest lessons the tree teaches us is that movement depends upon structure. The tree does not force water upward through muscular effort. Its architecture allows water to move. Likewise, efficient circulation within the human body depends upon the relationships between posture, connective tissue, internal pressure, breathing, and movement.

Structure Organizes Function

This principle becomes especially apparent when viewed through the lens of osteopathy and bodywork. Rather than functioning independently, the seven diaphragmatic actions of the body create a coordinated system of pressure regulators extending from the cranial base to the feet. The seven aspects of the diaphragm include the cranial diaphragm, oral cavity, thoracic outlet/inlet, respiratory diaphragm, pelvic floor, knees, and arches of the feet, which all contribute to maintaining healthy pressure relationships throughout the body. When these diaphragms move harmoniously, blood, lymph, cerebrospinal fluid, and connective tissue fluids move with greater efficiency. When restrictions develop, compensation appears elsewhere and structural organization begins to deteriorate. This brings us back to the internal arts, a process of reorganizing the interior of the body (Bisio, 2026).

The classical instructions for standing in San Ti appear deceptively simple, yet offer a roadmap for interacting with and influencing these structures and processes. When standing one should pay close attention to the following alignments:

The Head Presses Up.
Erect the Neck.
Drop (Hang) the Shoulders.
The Kua Embrace.
The Forearms Wrap the Elbows.
Lift the Knee.
Lift the Anus.
The Palm Hearts Draw Inward. (Liu, W., 2017)

At first these instructions seem to describe posture. With practice they become instructions for organizing our structure. Each adjustment changes pressure relationships throughout the body. Breathing becomes quieter, connective tissues begin transmitting force more efficiently, the diaphragms coordinate with one another. Balance improves not because muscular effort increases, but because unnecessary effort slowly, very slowly, disappears. Standing still reveals a remarkable truth, stillness is not the absence of movement, it is the absence of unnecessary movement.

Within apparent stillness the body remains incredibly active. Every breath alters pressure, every heartbeat sends waves through the vascular system. Lymphatic fluids continue to circulate while connective tissues deform and then recoil. Cells are in constant communication. Standing practice teaches us not to create these movements, but to organize and tune into them.

Working with patients recovering from surgery has continually reinforced this perspective. Following joint replacement or traumatic injury, swelling often develops not because the body has forgotten how to heal, but because the normal organization of fluid movement has been disrupted. Scar tissue alters mechanical relationships, pressure gradients change and lymphatic pathways become restricted. Healthy circulation is interrupted and fluids pool around the site of injury or surgery. Whether treating chronic lymphedema following hip replacement, persistent swelling after knee surgery, or venous insufficiency accompanied by lower abdominal heaviness, the clinical objective remains remarkably consistent:

Restore Organization

Rather than forcing fluid through congested tissues, treatment seeks to reopen relationships throughout the entire system. For instance, when I work with patients who have chronic fluid retention post-surgery we often see a significant reduction in swelling during the treatment session. When a knee is retaining fluid it is helpful to first go one joint above to the hip and waist (Kua). Working on the structures around the Kua opens the waterways from the torso to the legs, then I will work the structures around the knee and down to the ankle before encouraging fluids to return from the foot back to the Kua. In this sense we are digging, dredging or opening the waterways of the body, clearing the blockages and manually circulating the water back to the center of the body to encourage it to begin to circulate again. In some cases you can see and feel the fluids moving out of the chronically swollen joint in real time, other times patients report reduction in swelling later that day and in most cases more frequent urination for a short period following treatment as excess fluids are expelled.

Recent developments in biophysics invite us to revisit these observations from another perspective. Research into intracellular water, connective tissue, mechanotransduction, and the behavior of water near living structures raises fascinating questions about how living tissues organize themselves. For example, water behaves very differently in a bowl or glass than it does inside of a cell or near hydrophilic collagen fibers. Investigators such as Gerald Pollack have encouraged new discussions about the complexity of water within living systems, while others like Dr. James Oschman have explored how structure, pressure, and electromagnetic phenomena may contribute to biological organization (Oschman, 2015).

For centuries Chinese physicians have described health as the harmonious movement of Qi, Blood, and Body Fluids. Disease was often understood not merely as damage to individual tissues but as a disturbance in the relationship amongst them. Viewed through this lens, internal arts do not produce Qi, they cultivate the conditions in which Qi can flourish. When posture becomes organized, breathing becomes organized. When breathing becomes organized, pressure becomes organized. When pressure becomes organized, fluid movement becomes organized. When the organism functions as an integrated whole, the classical descriptions of free-flowing Qi reveal themselves; not as an isolated phenomenon, but as the expression of an ordered living system. In Xing Yi Quan we use San Ti and other foundational practices such as Tu Na Si Ba and Slow Pi Quan to facilitate this organization and build the proper structure within ourselves.

“Qi and strength share the same root. If Qi is sufficient, strength can manifest. In talking about the relationship between power and posture, it is said that one must seek to have sufficient Qi in order to train the posture and that you must also pay attention to the posture in training Qi, for both Qi and posture are interdependent. The difference is that posture can be shown externally and can be seen and Qi flows deeply and internally and cannot be observed. Thus students who pay attention [only] to the posture neglect the flow of Qi. This is why attending to posture, Qi and strength is repeatedly mentioned in this text” (Liu, W., 2017).

The image of “standing like a tree” now takes on a richer meaning. A healthy tree does not strive to move water upward, it has developed a structure that allows water to move naturally. Likewise, the purpose of San Ti, Tu Na Si Ba or Slow Pi Quan is not to accumulate tension or force extraordinary power. It is to cultivate a body whose structure is so well organized that movement, circulation, adaptability, and vitality arise with little to no effort.

The internal arts remind us that health is not merely the absence of disease or the possession of strength. It is the capacity of a living system to organize itself continuously in response to an ever-changing world. Like the tree, we become strongest not by resisting nature, but by participating in its remarkable order.
