Ecstatic

Ecstasy (from Ancient Greek ἔκστασις ékstasis) is a subjective experience of total involvement of the subject, with an object of his or her 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 because of being aware of other objects, thus 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. The word is also used to refer to any heightened state of consciousness or intensely pleasant experience. It is also used more specifically to denote states of awareness of non-ordinary mental spaces, which may be perceived as spiritual (the latter type of ecstasy often takes the form of religious ecstasy).

From a psychological perspective, ecstasy is a loss of self-control and sometimes a temporary loss of consciousness, which is often associated with religious mysticism, sexual intercourse and the use of certain drugs. For the duration of the ecstasy the ecstatic is out of touch with ordinary life and is capable neither of communication with other people nor of undertaking normal actions. The experience can be brief in physical time, or it can go on for hours. Subjective perception of time, space or self may strongly change or disappear during ecstasy. For instance, if one is concentrating on a physical task, then any intellectual thoughts may cease. On the other hand, making a spirit journey in an ecstatic trance involves the cessation of voluntary bodily movement.

Ecstasy can be deliberately induced using religious or creative activities, meditation, music, dancing, breathing exercises, physical exercise, sexual intercourse or consumption of psychotropic drugs. The particular technique that an individual uses to induce ecstasy is usually also associated with that individual's particular religious and cultural traditions. Sometimes an ecstatic experience takes place due to occasional contact with something or somebody perceived as extremely beautiful or holy, or without any known reason. "In some cases, a person might obtain an ecstatic experience 'by mistake'. Maybe the person unintentionally triggers one of the, probably many, physiological mechanisms through which such an experience can be reached. In such cases, it is not rare to find that the person later, by reading, looks for an interpretation and maybe finds it within a tradition."
