a person beyond the state of Clear who, through higher auditing levels, is advancing to the full state of Operating Thetan (OT). An Operating Thetan is a state of beingness. It is a being "at cause over matter, energy, space, time, form and life." Operating comes from "able to operate without dependency on things," and Thetan is the Greek letter theta (0), which the Greeks used to represent thought or perhaps spirit, to which an n is added to make a noun in the modern style used to create words in engineering. It is also 0n or "theta to the nth degree," meaning unlimited or vast. The pre-OT levels are New OT I through New OT VII. The actual OT levels begin at New OT VIII.
