An out-of-body experience (OBE or sometimes OOBE) is an experience that typically involves a sensation of floating outside one's body and, in some cases, the feeling of perceiving one's physical body as if from a place outside one's body. The term out-of-body experience was introduced in 1943 by G. N. M. Tyrrell in his book Apparitions, and was adopted by researchers such as Celia Green and Robert Monroe as an alternative to belief-centric labels such as "astral projection", "soul travel", or "spirit walking".

OBEs can be induced by brain traumas, sensory deprivation, near-death experiences, dissociative and psychedelic drugs, dehydration, sleep, and electrical stimulation of the brain, among others. It can also be deliberately induced by some. One in ten people have an OBE once, or more commonly, several times in their life.

Formlessness was a concept first introduced by Bataille in 1929, when he wrote about 'l'informe' (formless) in the surrealist journal Documents 1929–30.

To Bataille, l'informe was about destroying categories and knocking art off its metaphorical pedestal so that it sat in the gutter. He rejected high-minded humanism which he said elevated form to an idealised notion, and celebrated the debased. The concept of formlessness was re-introduced by the cultural theorists Rosalind Krauss and Yves-Alain Bois in 1996, when they used Bataille's notion of 'l'informe' in an exhibition at the Centre Pompidou in Paris called Formless: A User's Guide.

They argued that artists throughout the twentieth century, from the abstract expressionists, to post-modern artists like Mike Kelley and Cindy Sherman, have used formlessness as a tool for creativity, not to elevate art, but to get it down and dirty. They gave the example of Jackson Pollock, who dripped paint onto a canvas that was laid out on the floor. The paint would get mixed up with the ash dropping from the artist's cigarette and other bits of detritus, all of which would end up in the final work of art.

WHAT IS MEANT BY OPERATING THETAN (OT)?

Operating Thetan (OT) is a spiritual state of being above Clear. By Operating is meant “able to act and handle things” and by Thetan is meant “the spiritual being that is the basic self.” An Operating Thetan, then, is one who can handle things without having to use a body of physical means. Basically, one is oneself, can handle things and exist without physical support or assistance. It doesn’t mean one becomes God. It means one becomes wholly oneself.
Basic levels of Scientology help a person deal with his personal relationships and day-to-day problems, to free his attention to address higher aspects of existence. At the level of Operating Thetan, one deals with his own immortality as a spiritual being.

Like any other spiritual level in Scientology, the state of OT is attained by proceeding through a series of gradient steps, each one slightly more advanced than the last and each with its own ability gained. The precise sequence is firmly established and variations from that sequence are unproductive. Thus, it would be fruitless to try to move somebody onto the OT levels before he is ready for them. One might as well demand that a baby run before learning to crawl and learning to walk. Similarly, in Scientology individuals can only receive the benefits of the counseling that brings one to OT after completion of more basic steps.
At the level of OT, Scientologists study the very advanced materials of L. Ron Hubbard’s research. According to those who have achieved OT, the spiritual benefits obtained surpass description.
