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 or 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.
