... This is the first time such an effect is highlighted through self-reported phenomenology related to AICT and shows that the resting state itself contains information revealing that a trait that can be associated with change during this state. These findings align with anthropological research (Friedman & Hartelius, 2013;Tart, 1980), indicating that individual resting states should be considered when assessing the effects of NOC. Similar studies in hypnosis show that individuals with higher hypnotizability and absorption traits report richer experiences than those with lower traits (Kumar & Pekala, 1988). ...

... (Ludwig, 1966, p. 225) Continuing along these lines, Tart (1975) introduced a systems model of states of consciousness, that helped to lay the foundation for the study of ASCs by defining key concepts such as discrete and baseline states of consciousness, mentioned earlier, as well as examining the process of inducing ASCs. Furthermore, in proposing the development of state specific sciences, Tart (1972 Tart ( , 1973) proposed a foundational broadening of the scientific method, suggesting that science could and should be undertaken by trained observers from within various ASCs in order to fully explore the fundamental nature of consciousness. ...

... (Emic categories like spirits, apparitions, and spirit possession are generally established phenomena also but, involving complex combinations of several different psi, psychological, and other elements as they do, they are not at all well understood in terms of the specific psi contributions to each.) Although 15% of American scientists believe psi is established and 50% more believe psi is possible and worthy of study (see Tart 1980 andWade 1980), anthropologists, judging from my observations, have the lowest rate of belief (physicists probably have the highest). This is to be expected, since anthropologists have extensive training about psychosocial variables of supernatural beliefs and thus are more aware of a range of alternative explanations for the possible causes of belief systems. ...

... We guessed that his agent was too disturbed by or unbelieving of the material in the manuscript to try to market it! I asked Monroe for a copy of the manuscript and sent it to the editor who had overseen the paperback edition of my Altered States of Consciousness book (Tart 1969), Bill Whitehead. Whitehead was not very interested in weird stuff, but he took my word that Journeys would be interesting to some people, so he took the manuscript home to read. ...

... Answers concerning relaxation and everyday thoughts were categorised as indicating slight hypnosis, reports of strange bodily sensations like heaviness or lightness and even paralysis were associated with moderate hypnosis, and those whose responses were of spontaneous mental creativity including imagery and exceptional affective experiences were scored as highly hypnotised, according to the neurophenomenology of 'neutral' hypnosis (Cardeña et al. 2013) and the kind of items (relaxation, sensorimotor, and cognitive) scored by the Stanford Hypnotic Susceptibility Scale (Halligan and Oakley 2013). A scale for subjective 'hypnotic depth' was also used; to determine how deeply hypnotised the subjects felt during scanning (Tart 1970;Wagstaff et al. 2007), we asked the following question right after the scanning session: From 1 to 10 with 1 being not hypnotised and 10 being as deeply hypnotised as you have ever been, how deeply hypnotised did you feel during scanning? (Deeley et al. 2012). ...

... As many theorists stress, the essence of the ASCs is the qualitative shift in the subjective experience on the part of the individual being in the altered state (see Orne, 1959;Fromm, 1977;Ludwig, 1972;Tart, 1972). These experiences are unusual, unique, and many times uncertain. ...

... Altered States of Consciousness generally refer to mental states that deviate from what is considered to be a normal waking state of awareness ( Figure 5; Laureys, Perrin, & Brédart, 2007;Ludwig, 1966). A subclass of these mental states can be voluntarily induced through techniques such as meditation, hypnosis and lucid dreaming, as well as through psychoactive substances or pharmacological agents (Tart, 1969a(Tart, , 1969bRevonsuo, Kallio, & Sikka, 2009). Consistent reports of profound personal, psychological and spiritual insight during intentionally induced altered states of consciousness suggest that certain features of these experiences may share common underlying neural activity, and may have therapeutic applications in the treatment of some psychiatric disorders such as major depression and substance dependence (dos Santos et al., 2016). ...

... Yet at this very moment depth psychology began to open the psyche, as it were, from the bottom, giving birth to a revitalized place for humanity within the cosmos (cf. Tarnas, 2006). Freud's model of the psyche is often visualized as an iceberg in which the ego is but a small part that emerges from the waters of the unconscious; in Jung's view the ego might instead be pictured as an island that, if followed deeply enough into the unconscious, becomes the whole world. ...
