Near-death experience
A near-death experience (NDE) is a profound personal experience associated with death or impending death which researchers describe as having similar characteristics. When positive, which the great majority are, such experiences may encompass a variety of sensations including detachment from the body, feelings of levitation, total serenity, security, warmth, joy, the experience of absolute dissolution, review of major life events, the presence of a light, and seeing dead relatives.
Eight-circuit model of consciousness
The eight-circuit model of consciousness is a holistic model originally presented as psychological philosophy (abbreviated "psy-phi") by Timothy Leary in books including Neurologic (1973) and Exo-Psychology (1977), later expanded on by Robert Anton Wilson in his books Cosmic Trigger (1977) and Prometheus Rising (1983), and by Antero Alli in his books Angel Tech (1985) and The Eight-Circuit Brain (2009), that suggests "eight periods [circuits]" within the model.
Subtle body
A subtle body is a "quasi material" aspect of the human body, being neither solely physical nor solely spiritual, according to various esoteric, occult, and mystical teachings. This contrasts with the mind–body dualism that has dominated Western thought. The subtle body is important in the Taoism of China and Dharmic religions such as Hinduism, Buddhism, and Jainism, mainly in the branches which focus on tantra and yoga, where it is known as the Sūkṣma-śarīra (सूक्ष्म शरीर).
Ecstasy (emotion)
Ecstasy () is a subjective experience of total involvement of the subject with an object of their awareness. In classical Greek literature, it refers to removal of the mind or body "from its normal place of function." Total involvement with an object of interest is not an ordinary experience. Ecstasy is an example of an altered state of consciousness characterized by diminished awareness of other objects or the total lack of the awareness of surroundings and everything around the object.
Hypnagogia
Hypnagogia is the transitional state from wakefulness to sleep, also defined as the waning state of consciousness during the onset of sleep. Its opposite state is described as hypnopompia the transitional state from sleep into wakefulness. Mental phenomena that may occur during this "threshold consciousness" phase include hypnagogic hallucinations, lucid dreaming, and sleep paralysis. The word hypnagogia is sometimes used in a restricted sense to refer to the onset of sleep, and contrasted with hypnopompia, Frederic Myers's term for waking up.
Astral projection
Astral projection (also known as astral travel) is a term used in esotericism to describe an intentional out-of-body experience (OBE) that assumes the existence of a subtle body, known as the astral body or body of light, through which consciousness can function separately from the physical body and travel throughout the astral plane. The idea of astral travel is ancient and occurs in multiple cultures. The term "astral projection" was coined and promoted by 19th-century Theosophists.
Self-transcendence
Self-transcendence is a personality trait that involves the expansion of personal boundaries, including, potentially, experiencing spiritual ideas such as considering oneself an integral part of the universe. Several psychologists, including Viktor Frankl, Abraham Maslow, Pamela G. Reed, C. Robert Cloninger, Lars Tornstam, and Scott Barry Kaufman have made contributions to the theory of self-transcendence. Self-transcendence is distinctive as the first trait concept of a spiritual nature to be incorporated into a major theory of personality.
