Trance denotes any state of awareness or consciousness other than normal waking consciousness. Trance states may occur involuntarily and unbidden.
The term trance may be associated with hypnosis, meditation, magic, flow, and prayer. It may also be related to the earlier generic term, altered states of consciousness, which is no longer used in "consciousness studies" discourse.
Trance in its modern meaning comes from an earlier meaning of "a dazed, half-conscious or insensible condition or state of fear", via the Old French transe "fear of evil", from the Latin transīre "to cross", "pass over". This definition is now obsolete.
Wier, in his 1995 book, Trance: from magic to technology, defines a simple trance (p. 58) as a state of mind being caused by cognitive loops where a cognitive object (thoughts, images, sounds, intentional actions) repeats long enough to result in various sets of disabled cognitive functions. Wier represents all trances (which include sleep and watching television) as taking place on a dissociated trance plane where at least some cognitive functions such as volition are disabled; as is seen in what is typically termed a 'hypnotic trance'. With this definition, meditation, hypnosis, addictions and charisma are seen as being trance states. In Wier's 2007 book, The Way of Trance, he elaborates on these forms, adds ecstasy as an additional form and discusses the ethical implications of his model, including magic and government use which he terms "trance abuse".
John Horgan in Rational Mysticism (2003) explores the neurological mechanisms and psychological implications of trances and other mystical manifestations. Horgan incorporates literature and case-studies from a number of disciplines in this work: chemistry, physics, psychology, radiology and theology.
The following are some examples of trance states:
Trance conditions include all the different states of mind, emotions, moods and daydreams that human beings experience. All activities which engage a human involve the filtering of information coming into sense modalities, and this influences brain functioning and consciousness. Therefore, trance may be understood as a way for the mind to change the way it filters information in order to provide more efficient use of the mind's resources.
Trance states may also be accessed or induced by various modalities and is a way of accessing the unconscious mind for the purposes of relaxation, healing, intuition and inspiration. There is an extensive documented history of trance as evidenced by the case-studies of anthropologists and ethnologists and associated and derivative disciplines. Hence trance may be perceived as endemic to the human condition and a Human Universal. Principles of trance are being explored and documented as are methods of trance induction. Benefits of trance states are being explored by medical and scientific inquiry. Many traditions and rituals employ trance. Trance also has a function in religion and mystical experience.
Castillo (1995) states that: "Trance phenomena result from the behavior of intense focusing of attention, which is the key psychological mechanism of trance induction. Adaptive responses, including institutionalized forms of trance, are 'tuned' into neural networks in the brain and depend to a large extent on the characteristics of culture. Culture-specific organizations exist in the structure of individual neurons and in the organizational formation of neural networks."
Hoffman (1998: p. 9) states that: "Trance is still conventionally defined as a state of reduced consciousness, or a somnolent state. However, the more recent anthropological definition, linking it to 'altered states of consciousness' (Charles Tart), is becoming increasingly accepted."
Hoffman (1998, p. 9) asserts that: "...the trance state should be discussed in the plural, because there is more than one altered state of consciousness significantly different from everyday consciousness."
According to Hoffman (1998: p. 10), pilgrims visited the Temple of Epidaurus, an asclepieion, in Greece for healing sleep. Seekers of healing would make pilgrimage and be received by a priest who would welcome and bless them. This temple housed an ancient religious ritual promoting dreams in the seeker that endeavored to promote healing and the solutions to problems, as did the oracles. This temple was built in honor of Asclepios, the Greek god of medicine. The Greek treatment was referred to as incubation, and focused on prayers to Asclepios for healing. The asclepion at Epidaurus is both extensive and well-preserved, and is traditionally regarded as the birthplace of Asclepius. (For a comparable modern tool see Dreamwork.)
Stories of the saints in the Middle Ages, myths, parables, fairy tales, oral lore and storytelling from different cultures are themselves potentially inducers of trance. Often literary devices such as repetition are employed which is evident in many forms of trance induction. Milton Erickson used stories to induce trance as do many NLP practitioners.
From at least the 16th century it was held that march music may induce soldiers marching in unison into trance states where according to apologists, they bond together as a unit engendered by the rigors of training, the ties of comradeship and the chain of command. This had the effect of making the soldiers become automated, an effect which was widely evident in the 16th, 17th and 18th century due to the increasing prevalence of firearms employed in warcraft. Military instruments, especially the snare drum and other drums were used to entone a monotonous ostinato at the pace of march and heartbeat. High-pitched fifes, flutes and bagpipes were used for their "piercing" effect to play the melody. This would assist the morale and solidarity of soldiers as they marched to battle.
Joseph Jordania recently proposed a term battle trance for this mental state, when combatants do not feel fear and pain, and when they lose their individual identity and acquire a collective identity.
The Norse Berserkers induced a trance-like state before battle, called Berserkergang. It is said to have given the warriors superhuman strength and made them impervious to pain during battle. This form of trance could have been induced partly due to ingestion of hallucinogenic mushrooms.
As the mystical experience of mystics generally entails direct connection, communication and communion with Deity, Godhead and/or god; trance and cognate experience are endemic. (see Yoga, Sufism, Shaman, Umbanda, Crazy Horse, etc.)
Many Christian mystics are documented as having experiences that may be considered as cognate with trance, such as: Hildegard of Bingen, John of the Cross, Meister Eckhart, Saint Theresa (as seen in the Bernini sculpture) and Francis of Assisi.
Taves (1999) charts the synonymic language of trance in the American Christian traditions: power or presence or indwelling of God, or Christ, or the Spirit, or spirits. Typical expressions include "the indwelling of the Spirit" (Jonathan Edwards), "the witness of the Spirit" (John Wesley), "the power of God" (early American Methodists), being "filled with the Spirit of the Lord" (early Adventists; see charismatic Adventism), "communing with spirits" (Spiritualists), "the Christ within" (New Thought), "streams of holy fire and power" (Methodist holiness), "a religion of the Spirit and Power" (the Emmanuel Movement), and "the baptism of the Holy Spirit" (early Pentecostals). (Taves, 1999: 3)
Taves (1999) well-referenced book on trance charts the experience of Anglo-American Protestants and those who left the Protestant movement beginning with the transatlantic awakening in the early 18th century and ending with the rise of the psychology of religion and the birth of Pentecostalism in the early 20th century. This book focuses on a class of seemingly involuntary acts alternately explained in religious and secular terminology. These involuntary experiences include uncontrolled bodily movements (fits, bodily exercises, falling as dead, catalepsy, convulsions); spontaneous vocalizations (crying out, shouting, speaking in tongues); unusual sensory experiences (trances, visions, voices, clairvoyance, out-of-body experiences); and alterations of consciousness and/or memory (dreams, somnium, somnambulism, mesmeric trance, mediumistic trance, hypnotism, possession, alternating personality) (Taves, 1999: 3).
Trance-like states are often interpreted as religious ecstasy or visions and can be deliberately induced using a variety of techniques, including prayer, religious rituals, meditation, pranayama (breathwork or breathing exercises), physical exercise, coitus (and/or sex), music, dancing, sweating (e.g. sweat lodge), fasting, thirsting, and the consumption of psychotropic drugs such as cannabis. Sensory modality is the channel or conduit for the induction of the trance. Sometimes an ecstatic experience takes place in occasion of contact with something or somebody perceived as extremely beautiful or holy. It may also happen without any known reason. The particular technique that an individual uses to induce ecstasy is usually one that is associated with that individual's particular religious and cultural traditions. As a result, an ecstatic experience is usually interpreted within the context of a particular individual's religious and cultural traditions. These interpretations often include statements about contact with supernatural or spiritual beings, about receiving new information as a revelation, also religion-related explanations of subsequent change of values, attitudes and behavior (e.g. in case of religious conversion).
Benevolent, neutral and malevolent trances may be induced (intentionally, spontaneously and/or accidentally) by different methods:
The phenomenon of auditory driving is culturally still clearly evident and may be found in electronic dance music culture (one style is particularly called Trance), which in many ways may be considered a modern version of shamanism. The same effect is caused by many jam bands. Churches which chant their services may also induce the same effects resulting in a trance state through the use of odd inflections and off-kilter or polyrhythmic structures. Similarly, white noise has been scientifically documented to assist neural connectivity, creativity and problem-solving.
The usage of repetitive rhythms to induce trance states is an ancient phenomenon. Throughout the world, shamanistic practitioners have been employing this method for millennia. Anthropologists and other researchers have documented the similarity of shamanistic auditory driving rituals among different cultures.
Said simply, entrainment is the synchronization of different rhythmic cycles. Breathing and heart rate have been shown to be affected by auditory stimulus, along with brainwave activity. The ability of rhythmic sound to affect human brainwave activity, especially theta brainwaves, is the essence of auditory driving, and is the cause of the altered states of consciousness that it can induce.
The music genre of Trance music is supposed to have the same effect on the human mind as military drums, causing listeners to dance in unison with simple movements including head bobs, light bouncing/jumping and humming.
Nowack and Feltman have recently published an article entitled "Eliciting the Photic Driving Response" which states that the EEG photic driving response is a sensitive neurophysiological measure which has been employed to assess chemical and drug effects, forms of epilepsy, neurological status of Alzheimer's patients, and physiological arousal. Photic driving also impacts upon the psychological climate of a person by producing increased visual imagery and decreased physiological and subjective arousal. In this research by Nowack and Feltman, all participants reported increased visual imagery during photic driving, as measured by their responses to an imagery questionnaire.
Dennis Wier (http://www.trance.edu/papers/theory.htm Accessed: 6 December 2006) states that over two millennia ago Ptolemy and Apuleius found that differing rates of flickering lights affected states of awareness and sometimes induced epilepsy. Wier also asserts that it was discovered in the late 1920s that when light was shined on closed eyelids it resulted in an echoing production of brainwave frequencies. Wier also opined that in 1965 Grey employed a stroboscope to project rhythmic light flashes into the eyes at a rate of 10–25 Hz (cycles per second). Grey discovered that this stimulated similar brainwave activity.
Research by Thomas Budzynski, Oestrander et al., in the use of brain machines suggest that photic driving via the suprachiasmatic nucleus and direct electrical stimulation and driving via other mechanisms and modalities, may entrain processes of the brain facilitating rapid and enhanced learning, produce deep relaxation, euphoria, an increase in creativity, problem solving propensity and may be associated with enhanced concentration and accelerated learning. The theta range and the border area between alpha and theta has generated considerable research interest.
Charles Tart provides a useful working definition of kinesthetic driving. It is the induction of trance through the sense of touch, feeling or emotions. Kinesthetic driving works through a process known as entrainment.
The rituals practiced by some athletes in preparing for contests are dismissed as superstition, but this is a device of sport psychologists to help them to attain an ecstasy-like state. Interestingly, Joseph Campbell had a peak experience whilst running. Roger Bannister on breaking the four-minute mile (Cameron, 1993: 185): "No longer conscious of my movement, I discovered a new unity with nature. I had found a new source of power and beauty, a source I never dreamt existed." Roger Bannister later became a distinguished neurologist.
Sufism (the mystical branch of Islam) has theoretical and metaphoric texts regarding ecstasy as a state of connection with Allah. Sufi practice rituals (dhikr, sema) use body movement and music to achieve the state.
Divination is a cultural universal which anthropologists have observed as being present in many religions and cultures in all ages up to the present day (see sibyl). Divination may be defined as a mechanism for fortune-telling by ascertaining information by interpretation of omens or an alleged supernatural agency. Divination often entails ritual, and is often facilitated by trance.
In Tibet, oracles have played, and continue to play, an important part in religion and government. The word oracle is used by Tibetans to refer to the spirit, deity or entity that enters those men and women who act as media between the natural and the spiritual realms. The media are, therefore, known as kuten, which literally means, "the physical basis".
The Dalai Lama, who lives in exile in northern India, still consults an oracle known as the Nechung Oracle, which is considered the official state oracle of the government of Tibet. He gives a complete description of the process of trance and possession in his book Freedom in Exile .
Convergent disciplines of neuroanthropology, ethnomusicology, electroencephalography (EEG), neurotheology and cognitive neuroscience, amongst others, are conducting research into the trance induction of altered states of consciousness resulting from neuron entrainment with the driving of sensory modalities, for example polyharmonics, multiphonics, and percussive polyrhythms through the channel of the auditory and kinesthetic modality.
Neuroanthropology and cognitive neuroscience are conducting research into the trance induction of altered states of consciousness (possibly engendering higher consciousness) resulting from neuron firing entrainment with these polyharmonics and multiphonics. Related research has been conducted into neural entraining with percussive polyrhythms. The timbre of traditional singing bowls and their polyrhythms and multiphonics are considered meditative and calming, and the harmony inducing effects of this tool to potentially alter consciousness are being explored by scientists, medical professionals and therapists.
Scientific advancement and new technologies such as computerized EEG, positron emission tomography, regional cerebral blood flow, and nuclear magnetic resonance imaging, are providing measurable tools to assist in understanding trance phenomena.
Though a source of contention, there appear to be three current streams of inquiry: neurophysiology, social psychology and cognitive behaviorism. The neurophysiological approach is awaiting the development of a mechanism to map physiological measurements to human thought. The social-psychological approach currently measures gross subjective and social effects of thoughts and some critique it for lack of precision. Cognitive behaviorialists employ systems theory concepts and analytical techniques.
There are four principal brainwave states that range from high-amplitude, low-frequency delta to low-amplitude, high-frequency beta. These states range from deep dreamless sleep to a state of high arousal. These four brainwave states are common throughout humans. All levels of brainwaves exist in everyone at all times, even though one is foregrounded depending on the activity level. When a person is in an aroused state and exhibiting a beta brainwave pattern, their brain also exhibits a component of alpha, theta and delta, even though only a trace may be present.
The University of Philadelphia study on some Christians at the Freedom Valley Worship Center in Gettysburg, Pennsylvania, revealed that glossolalia-speaking (vocalizing or praying in unrecognizable form of language which is seen in members of certain Christian sects) activates areas of the brain out of voluntary control. In addition, the frontal lobe of the brain, which monitors speech, significantly diminished in activity as the study participants spoke glossolalia. Dr. Andrew B. Newberg, in analysis of his earlier studies as opposed to the MRI scans of the test subjects, stated that Buddhist monks in meditation and Franciscan nuns in prayer exhibited increased activity in the frontal lobe, and subsequently their behaviors, very much under voluntary control. The investigation found this particular beyond-body-control characteristic only in tongue-speakers (also see xenoglossia).
