Most theories map consciousness in a series of levels, some stages of which are more continuous or complex than others. Movement between stages is often bidirectional depending on internal and external conditions, with each mental ascension precipitating a change in reactivity. In the most basic sense, this alteration might lead to a reduced responsiveness as seen in anesthesiology; more abstract facets of tiered consciousness describe characteristics of profoundness, insight, perception, or understanding.
First appearing in the historical records of the ancient Mayan and Incan civilizations, various theories of multiple levels of consciousness have pervaded spiritual, psychological, medical, and moral speculations in both Eastern and Western cultures. Because of occasional and sometimes substantial overlap between hypotheses, there have recently been attempts to combine perspectives to form new models that integrate components of separate viewpoints.
 Historyseparation of church and state within any given civilization, the Ancient Mayans were among the first to propose an organized sense of each level, its purpose, and its temporal connection to humankind.
 MayansThe pyramid of consciousness has defined Mayan thought since the dawn of its civilization around 2000 BCE. Shamans and priests defined consciousness as an awareness of being aware, commonly referred to as a branch of metacognition. Because consciousness incorporates stimuli from the environment as well as internally, the Mayans believed it to be the most basic form of existence.
This existence, which they referred to as a loose translation of Cosmos, was made up of nine underworlds, depicted concretely through the nine-storied Pyramid of the Plumed Serpent in Chichen Itza, the Temple of the Jaguar in Tikal, and the Temple of the Inscriptions in Palenque. Within these nine underworlds are a specified "day" and "night", symbolizing periods of enlightenment, increased consciousness, and a heightened ability to interact with the universe.

 TheoriesEastern and Western cultures.
 Eastern perspectivesMany specific similarities have been drawn between Ancient Incan and historical Eastern views of tiered consciousness. Within most Eastern belief structures is the principle of the Cosmos as a joint entity with human awareness. Many branches stress the importance of AUM, also written Om, as the first sound produced after the world was created. Within Christianity this concept can be likened to the first words of Genesis regarding the holiness of the Word.
 Historical beliefsThe majority of Eastern perspectives assert that while consciousness originates from the sound of AUM, it has incorporated itself into flesh, which therefore gives humankind the goal of attaining oneness with the universe once more. Unlike Incan tradition, this oneness eliminates the separation of external and internal changes into one general indication of movement from stage to stage, commonly known as the Seven Shamanic Levels of Consciousness.
|Personal||Knowledge of the self and of personality|
|Mankind||Knowledge of human evolution and its experiences|
|Amphibious||Sense of separate identity between water and land||"Water" and "land" are symbolic of man and earth|
|Spherical||Perceive using the five bodily senses|
|Crystal||Perceive using emotions, thoughts, and purity||First inorganic level undistorted by bodily senses|
|Light||Attained only by near-death experiences; "tunnel effect"||First level above the human world|
|Sound||Only heard when the mind attunes itself to the world||From the primeval vibration AUM|
 Modern-day beliefsLike the Seven Shamanic Levels of Consciousness, yoga meditation practices as well as the teachings of Vedanta and Tantra emphasize the importance of self-realization, a concept that has become increasingly popular in Western philosophy after Abraham Maslow's and Carl Rogers's research in Humanistic Psychology.
 Advaita VedantaAdvaita Vedanta school of Hindu philosophy has been a topic of extensive study in both Eastern and Western cultures for its tiered depiction of the steps toward attaining self-realization. Unlike the unidirectional nature of Mayan, Inca, and ancient shamanic perspectives, however, this particular belief structure arranges the attainment of oneness with OM through rows and domains, each of which constitutes a fragment of this vibratory sound.
|1: "A"||Waking||Conscious||External, active conscious|
|2: "U"||Dreaming||Unconscious||Subtle images and impressions|
|3: "M"||Deep Sleep||Subconscious||Focus on latent or inactive thought patterns|
|4: "AUM"||Absolute||Consciousness||Equal permeation of all three levels|
 OM MantraSimilarly, the seven levels of consciousness defined by modern-day OM mantras strive to reach Absolute Reality through the same four realms described in the Advaita Vedanta, with three transitional tiers in between each.
- Between the first ("A") and second ("U") levels is the Unmani, similar to the Western concept of hypnagogia, or the movement from full alertness into stage 1 sleep
- Between the second ("U") and third ("M") levels is the Aladani, mirroring ideas of REM sleep
- Between the third ("M") and fourth ("AUM") levels is the Samadhi, or the attainment of deep absorption
 The VedaThe ancient Indian Vedas texts have lent a comparable view of unified consciousness, with a key difference in the purpose of human ascension from stage to stage. Instead of oneness with the universe, the Vedic vision of consciousness emphasizes the importance of attaining knowledge and pure intelligence.
 Ananda SanghaParamhansa Yogananda. Compared to the multi-dimensional theories of consciousness in shamanic and OM mantra perspectives, this particular ideological faction stresses simplicity rather than detail.
- Subconscious: relatively dim awareness; repository of remembered experiences and consequent mental impressions
- Conscious: rational awareness; guides daily decisions and can be influenced by others; input from the bodily senses
- Superconscious Awareness: intuition and heightened mental clarity; problem and solution are seen as one entity
 Western perspectivesFluctuations in consciousness theories are not particular to Eastern cultures. A surprising degree of overlap can be found within the field of health and social sciences with regard to dulled, standard, and heightened intensities of awareness, both naturally and as a result of injury or disorder.
 Psychological viewsLike many psychological theories within the particular field of psychoanalysis, one of the most popular theories of consciousness was proposed by Sigmund Freud, who described three facets of the psychic apparatus: the unconscious (id) or instinctual facet, the preconscious (ego) or rational facet, and the conscious (superego) or moral facet.
Although not unlike the Vedic vision of consciousness as a form of intelligence, Jean Piaget's theory of cognitive development is not commonly considered a form of knowledge awareness but instead as the evolution of the brain's capacity for thought throughout the human lifespan.
 Medical and pathological viewsSimilar to previously mentioned psychological views, medical and pathological perspectives often hypothesize tiered consciousness as a result of disease or disorders. The Altered Levels of Consciousness (ALC) theory is one such measure, in which a person's arousability and responsiveness to environmental stimuli are classified by their behavioral response.
 Glasgow Coma Scalecomatose state.
- Conscious: normal, attentive; oriented to self, place, and mind
- Confused: impaired or slowed thinking; disoriented
- Delirious: disoriented, restless, clear deficit in attention; possible incidence of hallucinations and delusions
- Somnolent: excessive drowsiness; little response to external stimuli
- Obtunded: decreased alertness, slowed motor responses; sleepiness
- Stuporous: conscious but sleep-like state associated with little or no activity; only responsiveness is in reaction to pain
- Comatose: no response to stimuli, cannot be aroused; no gag reflex or pupil response to light
 Relationship to schizophreniaRecent hypotheses have incorporated these ALC theories into the psychopathological study of schizophrenia, suggesting that each altered level of awareness is connected to a degree of suffering or shock experienced by the patient. As the situation increases in seriousness, patients will descend to lower levels of consciousness and consequentially lose the capacity to cry, to smile, or to exhibit a wide range of emotions when reacting to the environment.
In more physiologically based studies, scientists have found that while the reticular formation controls alertness, wakefulness, and arousal in the brain, many mental responses to internal and external stimuli are dictated through signals relayed to and from the thalamus. Propofol and other consciousness-altering drugs are therefore antagonists of thalamus activity, possibly leading to a drug-induced comatose state.
 Modern-day perspectivesAlthough many of the previously mentioned theories are still widely held today in various groups, beliefs, and areas of study, a majority of commonly accepted perspectives stem from just the past decade. These hypothesized structures of awareness draw from many historical and early eighteenth- or nineteenth-century theories to form an integrated and overarching generalization of consciousness as a means of determining inner and outer recognition of stimuli.
 Holder's three levels of consciousnessDerived loosely from his philosophy of the Kung Fu system, Philip Holder offers three levels of consciousness that feature distinct differences in the way in which they are reached.
|Spontaneous||The mind can react to the progression of life and does not account for future or past events; therefore, the mind develops an optimistic outlook|
|Calculated||This state reacts to events based on the perception of right and wrong and attempts to direct others accordingly; the mind is focused on achieving what it thinks should happen|
|Imposed||The mind is short sighted and clashes with the opposition; lack of awareness for surroundings amounts to failure in the long term|
 Barrett's seven levels of personal consciousnessexistential” needs directly connected to and dependent on the human condition, all of which are motivating factors for daily interactions.
|Survival||Feel protected or unprotected|
|Relationship||Feel in or out of a group|
|Self-esteem||Feel positive or negative about yourself|
|Transformation||Act out of your true self|
|Internal Cohesion||Find similarities between your views and goals|
|Making a Difference||Align your views with others to make a greater impact|
|Service||Live through voluntary service to meet your personal goals|
 Hawkins's Power vs. ForcePower vs. Force: The Hidden Determinants of Human Behavior, David R. Hawkins offers numerous levels of consciousness, which arguably maintain a more specific and psychologically driven perspective of internal awareness than the modern views previously mentioned. The features of each level are explicit enough that individuals can most likely place themselves in a stage depending on their perceived state.
- Shame: Close to 'rock bottom'; possibly caused by a life-threatening or traumatizing event
- Guilt: Questioning oneself; difficulty letting go of unfortunate past events
- Apathy: Defenselessness and weakness; minimal power to change the current situation
- Grief: Sadness, deep loss
- Fear: Uneasiness; feeling pressured or sensing a need to act quickly to change the current situation
- Desire: Greed; the need to acquire things; can lead to addictions
- Anger: Anxiety; typically a result of not meeting expectations while at lower levels
- Pride: False positive; happiness in high statuses or other superficial benefits; leads to defensiveness and rebellion
- Courage: Able to rationalize choices and control vision
- Neutrality: 'No strings attached'; content with current situation and no effort to change
- Willingness: Moving forward; openness to embark on new adventures
- Acceptance: Reactive; stepping out of comfort zones; putting goals and values to action after discovering them in lower levels
- Reason: Separating objectives and tackling tasks that align with strengths
- Love: Empathy; making decisions from true values
- Joy: Optimism, possibly caused by a life-changing event
- Peace: Completeness
- Enlightenment: Large impact; vision of progress
 Gibson's four states of consciousnessDr. Bob Rhondell Gibson, author of Notes on Personal Integration and Health and often recognized as a psychic healer, hypothesized the existence of four tiers of extrasensory awareness. Beyond being more applicable to internal states rather than reactions to the external environment, these stages contrast markedly with the previously mentioned modern theories through their emphasis on humankind's immediate interactions. Gibson does not focus on life progression or individual power to move between levels, but rather on momentary instances of personal experience.
|Sleep||Unaware of all surroundings; dreams may or may not occur|
|Waking Sleep||Sleepwalking; normal tasks can be performed but the individual is not receptive to what is taking place|
|Self-awareness||Able to identify surroundings and observe what is taking place|
|Objective awareness||Identify surrounding events without opinions or input|
 Attempts to combine theories
 Leary's 8-Circuit Model of Consciousnessthe Eight-Circuit Model of Consciousness, a psychologically based theory that unifies various interpretations of main altered states of awareness into a single meta-theory, or a hypothesis about an already existing hypothesis. In this case, Leary and Wilson state that the altered levels of consciousness defined in medical fields are products of eight differing brain structures within the human nervous system.
This concept not only connects psychology and the more medically focused studies of neurology and biology, but also incorporates elements of sociology, anthropology, physics, chemistry, and advanced mathematical formulas. Furthermore, critics argue that the inspiration for his theory stems at least indirectly from the Hindu chakra system.
|Biosurvival||The Breath of Consciousness||Infancy||Suckling, nourishment, cuddling, trust versus suspicion|
|Emotional-Territorial||Freud's Ego||Toddling||Emotions, domination, submission strategies, territory|
|Symbolic (Neuro-Semantic-Dexterity)||The Rational Mind||From human artifacts and symbol systems||Handling the environment, invention, calculation, prediction|
|Domestic (Socio-Sexual)||The "Adult" Personality||First mating experiences||Pleasure, reproduction, nurture|
|Neurosomatic||Zen-Yoga Mind-Body Connection||Neurological-somatic feedback and reprogramming||Consciousness of the body|
|Neuroelectric (Metaprogramming)||Psionic Electronic-Interface Mind||Re-imprinting and reprogramming earlier circuits||Perceived "realities", cybernetic consciousness|
|Neurogenetic (Morphogenetic)||Buddha-Monad "Mind"||Consciousness maturation||Evolutionary consciousness, DNA-RNA brain feedbacks|
|Psychoatomic (Quantum Non-Local)||Overmind||Consciousness maturity||Out-of-body experiences involving information beyond normal space-time awareness|
 Morin's integrationSimilar to Dr. Rondell Gibson's view of a simplified hierarchy of conscious states, Alain Morin describes a four-tiered integration of nine past awareness models, focusing explicitly on the two common aspects underlying each belief structure: the perception of the self in time and the complexity of those self-representations.
|Level||Description||Alternative titles in past theories|
|Unconsciousness||Non-responsive to self and environment||Consciousness, non-consciousness, arousal, limbic stage, sensorimotor cognition|
|Consciousness||Focusing attention on environment; processing incoming external stimuli||Non-conscious mind, ecological and interpersonal self, neocortical level, consciousness, sensorimotor awareness; core, peripheral, primary and minimal consciousness|
|Self-awareness||Focusing attention on self; processing private and public self-information||Consciousness, extended and private self, symbolic level, meta-representational self-consciousness, conceptual self-consciousness, self-concept; reflective, recursive, self and meta-consciousness|
|Meta-self-awareness||Aware that one is self-aware||Consciousness, extended self|
 Robert MonroeRobert Allan Monroe became known for his research into altered consciousness and "out-of-body experience". His book 1985 "Far Journeys" showed numerous levels of consciousness and infinite expansion of consciousness.
“The plants exist on levels of consciousness from one through seven. They are on a vibrational rate on the levels one through seven. It is the same pattern.
Animals exist on the levels of consciousness from eight through fourteen, and when a person attains, when a consciousness attains level fourteen, it can no longer go any higher unless it is willing to change its form of consciousness.
Levels of consciousness from fifteen through twenty-one are what you call human life on this earth.
When a person progresses to level of consciousness twenty one, he then has the choice of going higher or staying within the realm of human form, but he cannot go higher unless he is willing to give up human form.”
