Zouhuo rumo: when practice goes wrong

Evidence label: Tradition only

This article describes how traditional texts and modern psychiatry have written about inner practice going wrong. It reports what these sources say, with their limits. It does not diagnose anything, it is not a measure of risk, and it makes no health claims. If something feels wrong during or after practice, stop and talk to a doctor or another qualified professional.

In short

What this is: Chinese texts on inner practice have long warned that it can go astray. The phrase zouhuo rumo (走火入魔), “fire going astray and entering the demonic”, names that worry. In the 1980s and 1990s, during the Qigong boom, Chinese psychiatrists wrote about “qigong deviation” and “qigong-induced mental disorders”. The idea entered the Chinese classification of mental disorders and, as “qi-gong psychotic reaction”, an appendix of the American diagnostic manual. This article looks at what the old texts say, what that psychiatric literature found and did not find, and how the traditions advise caution. It is the fifth article of part two of our neigong series.

What the evidence says: The literature on Qigong and mental health problems consists mainly of case reports and clinical descriptions. A 1999 review found a conspicuous lack of controlled data, judged a causal link difficult to establish, and suggested that in many cases practice acted as a stressor in people who were already vulnerable. How often such problems occur is not known. Research on meditation in general also describes difficult experiences; the figures vary widely with the way studies are done, and none of this research tested the Six Healing Sounds.

What it means for your practice: The old texts and modern safety advice point in the same calm direction: practise gently, don’t force anything, don’t chase or cling to unusual experiences, learn from a teacher, and if something feels wrong, stop and see a professional. This literature is not a reason to be afraid of practice, and it is not a measure of risk; it is a reason to practise with care.

What tradition says

Label for this section: Tradition only (documented history; authorships traditional).

The phrase. The Taiwanese Ministry of Education’s Revised Mandarin Chinese Dictionary explains the two halves of the phrase separately. Zouhuo (走火), “the fire goes astray”, is a Daoist term for a practitioner who, in refining essence, qi and spirit, is impatient and pushes ahead too fast (急躁冒進), so that the inner qi “rushes about” (內氣亂竄) in a manic state. Rumo (入魔), “entering the demonic”, refers to the illusions that this produces. Later, the dictionary says, the whole phrase came to mean, more generally, that a practitioner confuses the illusions that arise in meditation with the real world; in everyday Chinese it now also simply means being obsessed with something [1]. Our article “Neidan, inner alchemy” gives the same short definition.

Ten demons and nine difficulties. The Zhong-Lü chuandao ji (鍾呂傳道集), the main text of the Zhong-Lü tradition of inner alchemy, has a chapter “On demons and difficulties” (論魔難第十七) [2]. Lü Dongbin asks how the “yin ghosts and evil demons” (陰鬼邪魔) that keep followers of the Way from ascending as immortals can be dealt with. Zhongli Quan’s answer begins not with demons but with ordinary life. The “nine difficulties” (九難) are needing food and clothing, demands from elders, the bonds of family love, fame and profit, sudden misfortune, “blind teachers” (盲師), quarrels about methods, flagging resolve, and wasted years. On teachers he is blunt: people who are in a hurry to find one “do not distinguish true from false” (急於求師，不擇真偽) [2].

The “ten demons” (十魔) come in three kinds: those met in the outside world, those met in dreams, and those met during inner observation (内观). They are pleasures of the senses, wealth, rank, the emotions, the suffering of one’s family, disasters, sages and deities, armies, music and beauty. Every description ends with the same advice: “if you see it, do not take it as real” (如見，不得認). The text explains why: “once you take it as real, you become attached; once you are attached, you cling” (既認則著，既著則執), and this is why people do not complete the Way. For what appears during inner observation, the advice is to “examine whether it is empty or real, and discern true from false; do not drift with the waves, taking a thief for your son” (當審其虛實，辨其真偽，不可隨波逐浪，認賊為子) [2]. The text then names a remedy from its own alchemical system; we report that it exists, but we do not share it.

A Buddhist manual: recognising the work of Māra. The Buddhist master Zhiyi (智顗, 538–597), whose short meditation manual we also read in “Song 松: relaxed and rooted” and “Stillness and posture”, gives a whole chapter to the same problem: “Recognising the work of Māra” (覺知魔事第八) [3]. Experiences that seem lovely, frightening or merely distracting can all, he writes, be “the work of Māra” if they unsettle the mind. His advice is to know them as “empty and deceptive” (虛誑), and to “neither worry nor fear, neither grasp nor reject” them (不憂不怖，亦不取不捨). “If the demon realm does not fade, there is no need to worry; if it fades, do not rejoice either” (若見魔境不謝，不須生憂；若見滅謝，亦勿生喜). In his view, it is the practitioner’s own fear or craving that disturbs the mind, “not the doing of Māra” (非魔所為). For that reason, he writes, a beginner “must stay close to a good spiritual friend” (初心行人，必須親近善知識), an experienced teacher [3]. His next chapter, on illness, adds that when the mind is “used wrongly” in practice, illness can arise from it (若用心失所，則四百四病因之發生); it also makes traditional claims about healing, which we do not repeat [3].

What the texts share. The two texts belong to different traditions, and their “demons” are religious ideas, not medical diagnoses. In our reading, though, they give strikingly similar practical advice: unusual experiences are to be noticed, not believed or chased; impatience and forcing are the danger; and a beginner should not practise alone without a trustworthy teacher.

Qigong deviation in modern China

Label for this section: Tradition only (documented history of medicine).

The Qigong boom. In the 1980s and 1990s Qigong became a mass movement in China; at its peak, according to the historian David Palmer, it attracted over 100 million practitioners [4]. Our article “What is Qigong?” describes this “qigong fever”, its charismatic masters, and how it ended. It was in this period that the problems of practice became a subject for psychiatrists.

“Qigong deviation”. The psychiatrist Sing Lee of the Chinese University of Hong Kong, writing in 2000, summarised the situation: “In the past two decades many reports of mental disorders induced by qigong have been published in the Chinese psychiatric literature” [5]. He explains the vocabulary. Health disturbances linked to Qigong are called piancha (偏差), “deviation”. In psychologically vulnerable people they are “believed to arise from the inappropriate application of Qigong or the inability to ‘terminate the qigong’ (shougong)”, or both; shougong (收功) is the closing of a practice session. When severe, such states are called zouhuo rumo: in the traditional picture, the flow of qi strays from its channels and becomes fire, and “a devil enters the person”, which Lee glosses as “metaphorically, referring to the emergence of psychotic symptoms” [5].

In the Chinese classification. China’s own diagnostic system, the Chinese Classification of Mental Disorders, took the idea up. In his review of its revised second edition (CCMD-2-R, 1995), Lee lists “qigong induced mental disorders” among the categories that the Chinese system adds to the international classification ICD-10 [6]; in the same letter of 2000 he notes that it appears there as a “culture related mental disorder” [5]. The third edition, CCMD-3, was finalised after field trials from 1996 to 2000 and published as diagnostic guidelines for psychiatrists across China [7]. It includes a group of culture-related mental disorders, and Lee names “qigong-induced mental disorder” among the culture-specific Chinese categories whose study “sheds light on” social change in China [8].

In the American manual. In the United States, the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV, 1994) included a glossary of “culture-bound syndromes” in an appendix. One entry is “qi-gong psychotic reaction”: an acute, time-limited episode with dissociative, paranoid or other symptoms that may occur after taking part in Qigong; the entry adds that people who become overly involved in the practice are especially vulnerable [9]. Not everyone agreed that this is specific to one culture. A team from the Vincent van Gogh Institute for Psychiatry in Venray, in the Netherlands, described a man who developed a brief psychosis after meditating, searched the literature for similar cases, and concluded that “the syndrome is not culture bound but sometimes classified in culture-bound taxonomies like Qi-gong Psychotic Reaction” [10].

What science says

Label for this section: Early evidence (case reports, clinical descriptions and reviews; the 1999 review found no controlled data on Qigong and mental health).

The 1999 review. A 1999 review by B. Y. Ng of the Institute of Mental Health in Singapore read the literature in Chinese and English [11]. His conclusions are careful. He found “a conspicuous lack of controlled data” on the effects of Qigong on mental health. Qigong, “when practised inappropriately, may induce abnormal psychosomatic responses and even mental disorders”; but “the ties between Qigong and mental disorders are manifold, and a causal relationship is difficult to establish”. He suggested that many so-called “Qigong-induced psychoses” may be better called “Qigong-precipitated psychoses”, “where the practice of Qigong acts as a stressor in vulnerable individuals” [11].

What is not known. Lee noted in 2000 that “the exact proportion of people engaging in qigong and developing psychiatric complications remains unknown”, and that some cases probably never reach a doctor [5]. So these reports say that such problems were described, not how often they happen. Case reports come to attention because something went wrong; they cannot show how common a problem is, or that practice caused it.

Not only Qigong. Lee also wrote that similar problems were “much less frequently described” in the meditation practices of other cultures [5]. Research since then has looked more closely. The Venray report found other published cases of psychosis after meditation: some were relapses of an existing psychotic disorder, others brief reactions in people with no psychiatric history; the authors concluded that meditation “can act as a stressor in vulnerable patients” [10]. A study led from Brown University interviewed Western Buddhist meditators and teachers and described 59 kinds of meditation-related experience. Their tone ranged from very positive to very negative, and the distress involved from “minimal and transient to severe and enduring”; the same experience was often interpreted and handled very differently by different people [12]. A 2020 systematic review of 83 studies of meditation, with about 6,700 participants in total, found reports of at least one kind of adverse event in 65% of the studies. It put the overall prevalence of adverse events at 8.3%, but the figure “varied considerably” with the type of study: 3.7% in experimental studies and 33.2% in observational ones. The most common were anxiety, depression and cognitive anomalies [13]. The authors argue for “a balanced perspective of meditation as a practice that may lead to both positive and negative outcomes” [13].

How strong is this evidence? It is thin, and it answers a narrower question than people often think. The Qigong literature is mostly case reports and clinical descriptions from the period of the mass Qigong movement of the 1980s and 1990s; none of it was a controlled study, and none of it looked at the Six Healing Sounds. The meditation studies are about meditation, not Qigong, and they mix many methods and definitions. Together they support a modest point: inner practices can sometimes bring difficult experiences, and people who are already vulnerable may be more affected. They do not tell you your own risk. For how to weigh studies like these, see “How to read a health study in 5 minutes”.

Where popular claims go beyond the evidence

Label for this section: Speculative.

“Qigong can drive you mad.” The literature does not show that. The 1999 review found a causal link difficult to establish and suggested that practice often acted as a stressor in people who were already vulnerable [11], and nobody knows how often such problems occur [5]. Frightening stories about Qigong are not a measure of risk.

“Zouhuo rumo means your qi literally catches fire, or that a demon takes hold of you.” These are images from a traditional way of describing experience. The dictionary defines the phrase through haste in practice and the illusions that follow [1], and Lee reads the “devil” as a metaphor for the emergence of psychotic symptoms [5]. We do not take a position on qi here; we only note that the language is traditional and figurative.

“It is a Chinese problem; it can’t happen in other traditions.” The Venray team, reviewing published cases of psychosis after meditation, concluded that the syndrome “is not culture bound” [10], and research with Western meditators describes difficult experiences too [12, 13].

“Strange experiences mean you are making progress, so push through.” The traditional texts quoted above say the opposite: don’t take such experiences as real, don’t grasp them, and don’t hurry [2, 3]. Modern safety advice says the same in plain words: signs such as dizziness or rising panic are a reason to stop, not to push on (see “Who should be careful with breathing practices”).

How this relates to the Six Healing Sounds, Qigong and neigong

Label for this section: Tradition only (documented history); my own approach is marked as mine, with its own label.

The warnings in this article come mainly from intensive inner cultivation: long seated practice, inner observation and inner alchemy, and, in the modern reports, the mass Qigong of the 1980s and 1990s. In our reading, they speak most directly to practices of that kind. That does not make any practice risk-free, and no study we found looked at the Six Healing Sounds either way. As our breathing-safety article puts it, the traditions sometimes describe sensations such as warmth or tingling as qi moving, “but it is not a safety test: dizziness, numbness, chest pain or rising panic during practice are signs to stop and breathe normally, whatever framework you use” (see “Who should be careful with breathing practices”).

If something feels wrong, stop. If during or after practice you feel dizzy, numb, panicky or confused, or your sense of what is real seems to shift, stop and breathe normally. If the feeling does not settle soon after you stop, or keeps coming back, talk to a doctor or another qualified health professional; in an emergency, call your local emergency number (112 in the EU, 999 in the UK). If you have, or have had, a mental health condition, talk to your doctor or therapist before you start a new practice, and read “Who should be careful with breathing practices” first. A good teacher of any tradition will tell you the same.

How I practise the sounds. My practice is breath-led: you breathe in quietly through the nose and breathe the six sounds out through the mouth, “voiced through the breath”, not sung, working over time towards a silent exhalation. The breathing stays slow and controlled throughout, with no breath holds and no fast breathing. In my immersions we practise the sounds standing, in the wuji posture (无极, “without limit”), for those who are able to stand comfortably. Neidan is not part of my immersions; we use neigong and visualisation.

In my immersions, there is never any pressure to keep going. People settle in quickly: they feel comfortable, they trust the space and the group, and they find a quiet security within themselves that lets them simply feel at home. Anyone can stop, sit down or breathe normally at any time, and I’m always close by. If something feels uncomfortable, you’re welcome to tell me, before, during or after a session, and we take it from there together. Your own sense of what feels right always comes first.

Label for the next paragraph: 🟠 Speculative · 🟣 Lived experience, from my own practice.

How I use visualisation. I add a visualisation in the spirit of neigong: you imagine yourself as the resonance, travelling with each sound to its organ, and with xi through the whole body (the triple burner; see “The triple burner”). It is not inner alchemy and not the inner observation of the texts above; it is a modern approach of my own, and it is marked as mine. This rests on my own experience and that of participants in my immersions, not on a scientific finding; I see my work as bridging the gap between the science and the experience. What can be felt is the vibration of your own voice, as “What resonance really is” explains. Lived experience is an honest account of what people notice; it is not proof, and you may notice something different. None of this is a health claim.

Resonance Heritage Qi is a personal, music-assisted practice inspired by Liu Zi Jue: connected to it, not a replacement for the traditional form or for study with a teacher of that tradition.
