What is qi? Cross-cultural perspectives on “vital energy” and its relevance to feng shui
Overview
Across many intellectual traditions there is a recurring claim that life is animated by a subtle, dynamic force. In classical Chinese thought this force is qi (also written chi). Related terms include Japanese ki, Sanskrit prana, the Greek pneuma, Hebrew ruach, and Polynesian mana. These notions are not identical, yet they converge on four motifs.
-
Breath or vapour as a metaphor for life.
-
A dynamic, processual field rather than a static substance.
-
Organisation of body, mind and environment into patterned flows.
-
Cultivation, regulation and alignment as practical aims.
Below I synthesise the most cited scholarly accounts of qi and its analogues, then situate qi explicitly within feng shui.
Qi in classical Chinese thought
Meaning and origins. Philological and medical histories describe qi as “breath, vapour, vital material” that condenses and disperses, forming and animating all phenomena, including the human body (Needham, 1956; Unschuld, 1985; Kuriyama, 1999). In early cosmology, qi differentiates into yin and yang and interacts with the five phases, which yields patterning across heavens, earth and human affairs (Lloyd & Sivin, 2002; Unschuld, 2003).
Medical theory. In the Huangdi neijing corpus, qi circulates through networks later mapped as channels. Different functional qi were distinguished, for example defensive qi and nutritive qi. Health meant adequate, harmonious movement of qi, while illness reflected depletion, blockage or disharmony (Unschuld, 2003; Scheid, 2002; Kuriyama, 1999).
Philosophical development. Neo-Confucian thinkers such as Zhang Zai and Zhu Xi described reality as patterns in the activity of qi, structured by principle but realised in concrete, ever-transforming movements. This yields a relational ontology in which form, affect and conduct arise from the configuration of qi rather than from a separate immaterial substance (Ames & Hall, 2001; Makeham, 2018).
Practice. Qigong, acupuncture and related arts aim to regulate qi through breath, posture, attention and the use of points along the channels. Modern clinical literature varies in quality, yet there is evidence that such practices can influence autonomic and inflammatory indices, which some scholars discuss under the rubric of biofield effects and complex regulatory networks (Lee, Pittler, & Ernst, 2003; Rubik et al., 2015; Jain, Hammerschlag, & Mills, 2015).
Qi and feng shui
Conceptual place. In feng shui, qi names the quality and movement of environmental influences that arise from landforms, watercourses, wind, orientation, boundaries and the spatial arrangement of built environments. Practice seeks to harvest, guide and harmonise qi so that dwellers experience flourishing rather than depletion (Feuchtwang, 1974; Bruun, 2003).
Landscape and siting. Classical manuals describe “dragon veins” and protective forms that gather auspicious qi while shielding harsh flows. Valleys and meanders collect and slow qi; abrupt exposures and straight, rushing flows are said to disperse or strike qi, with consequences for well-being and fortune (Feuchtwang, 1974; Bruun, 2003).
Architectural layout. Interiors are arranged to promote smooth circulation and balanced stillness. Entrances, corridors, sleeping and working positions are assessed for whether they receive, retain and modulate qi rather than leaking or congesting it. The yin-yang and five-phase correspondences provide a grammar for colour, material and functional zoning (Feuchtwang, 1974; Bruun, 2003).
Empirical study. Contemporary reviews note an emerging yet mixed empirical base. Environmental-psychology style studies report associations between feng shui-congruent layouts and self-reported comfort, preference and restorative responses, although causal mechanisms remain debated. A recent systematic review maps these studies and calls for preregistered designs and psychophysiology to test specific mechanisms, including stress regulation and attentional restoration (Han & Lin, 2023).
Comparative concepts
Japanese ki
Japanese discussions of ki emphasise lived attunement, embodied awareness and the felt dynamics of vitality that coordinate posture, breath and intention. Philosophers of the body analyse ki as a practical, experiential mediator of mind and body cultivated through arts such as aikido, noh and meditation (Yuasa, 1987; Nagatomo, 1992).
Sanskrit prana
In the Upanishads and later yoga texts, prana is the life force that sustains and integrates psychophysical functions. It differentiates into sub-vitalities associated with respiration, circulation and elimination, while breath disciplines are used to regulate attention and affect. Prana is ultimately linked to consciousness and liberation in yoga and Vedānta (Eliade, 1958; Dasgupta, 1922; Feuerstein, 2008).
Greek pneuma
Stoic physics treats pneuma as a warm, tension-bearing breath that pervades and organises living bodies and the cosmos. Degrees of tension account for cohesion in inanimate things, vitality in plants and animals, and rational functions in humans. Pneuma thus plays both physiological and cosmological roles (Long & Sedley, 1987; Hankinson, 2003).
Hebrew ruach
Biblical philology glosses ruach as wind, breath, spirit. It denotes life-imparting breath and divine agency animating persons and communities. While the theological frame differs from Chinese naturalism, the breath-life metaphor and animating function are convergent (Koehler & Baumgartner, 2001; Goldingay, 2003).
Polynesian mana
Ethnology describes mana as an efficacious power associated with persons, places and acts. Classic and modern analyses debate whether mana is primarily a generalised force, a sign of status and success, or a relational efficacy embedded in ritual and exchange, yet all emphasise potency that can be cultivated and transmitted (Codrington, 1891; Keesing, 1984; Tomlinson & Tengan, 2016; Blust, 2007).
What, then, is qi? A synthesis
-
Qi is a relational process, not a substance. It denotes the patterned activity through which things come to be, endure and transform. In humans, this register appears as metabolic, affective and attentional regulation. In landscapes, it appears as the qualities of shelter, aspect, movement and rest that environments afford (Ames & Hall, 2001; Kuriyama, 1999; Feuchtwang, 1974).
-
Qi articulates breath, body and world. The breath metaphor is not accidental. Breathing mediates between inside and outside and is the primary rhythmic regulator of arousal and feeling. Classical sources make breath training a privileged means to regulate qi, a point increasingly explored in psychophysiological research (Unschuld, 2003; Lee et al., 2003; Rubik et al., 2015).
-
Qi is normative. Harmonious qi is associated with vitality, adaptability and ethical comportment. Stagnant, scattered or excessive qi is associated with distress and misfortune. Hence the centrality of cultivation, alignment and design, from personal practice to urban siting and the micro-ecologies of rooms (Zhu Xi in Ames & Hall, 2001; Feuchtwang, 1974; Bruun, 2003).
-
Qi is a lens, not a measurement unit. Modern attempts to equate qi with a single physical entity are reductionist. More plausible is to treat qi as a historical framework that organises perceptions, practices and design decisions, some of which map to measurable regulatory systems such as autonomic, inflammatory and attentional networks (Kuriyama, 1999; Jain et al., 2015; Rubik et al., 2015).
Implications for research and practice
-
Conceptual clarity. Researchers should specify whether qi is used as a cultural-historical construct, a phenomenological descriptor of felt vitality, or a hypothesised biofield. Slippage among these levels confuses study design.
-
Mechanistic bridges. Hypotheses linking feng shui or qigong to outcomes should articulate candidate mediators, for example low-arousal safety cues, daylight, fractal visual complexity, ventilation and affordances for smooth circulation, then test them with preregistered measures.
-
Method pluralism. Textual, ethnographic and psychophysiological methods are complementary. The goal is not to force ancient concepts into modern physics, but to examine whether the practices built on these concepts reliably improve well-being.
Conclusion
Qi is best understood as a classical Chinese name for the dynamic, patterned process of animation that links breath, body and environment. The family resemblance with ki, prana, pneuma, ruach and mana lies in the intuition that life manifests through an enlivening movement that can be cultivated and aligned. In feng shui, this alignment is pursued through the design of places that gather, modulate and circulate qi, so that human activities are supported rather than strained.
