Originally coined in response to Phanerothyme  [manifest & spirit],
Psychedelic  [mind-revealing] is etymologically derived from
the Greek psychē and dēloun. Psychedelia is music, culture, or art
based on the experiences produced by psychedelic drugs.
(Cyberdelia is immersion in cyberspace as a psychedelic experience.)

Some peoples feel there is a spiritual dimension to these experiences
and as such have developed a suitable terminology to reflect this view:
Entheogen,  [generating the divine from within]
denotes "a generator of spiritual experience", from
Entheos  [god-within], meaning
full of the god, inspired, possessed.
A spiritual experience is defined by its significance
to the host/subject. Entheogenic has been posited as
an alternate descriptor of "the psychedelic experience"
(in lieu of hallucinogenic) though this is a subjective term.

The Psychedelion is the analytical dimension of the psyche,
The part of the mind through which information is analysed
and thereby assigned meaning which is therefore significant.
Psychedelos is the existential manifestation of said dimension,
It is expressed through the medium of a language.

Absurdus  [out-of-tune] is the nonsensical dimension of the psyche, a part of the mind comprised of uninterpreted data, proportionate to our own limitations rather than lacking in "actual meaning". If a noumenon cannot be processed in The Psychedelion then it is consigned to Absurdia wherein we accept the inability to understand/rationally analyse it at present, given the current context.

Entactus  [touch-within] is the physical dimension of the psyche, the part of the mind through which sensation is perceived and remembered. It is responsible for the conception of our body and it's senses.

An Aeon Dissociative negates Entactus to deduce Absudia.
A Seraphic Deliriant posits Choler to induce Absurdia.
