WHAT IS A THETAN?

Apparently this is a concept known since the beginning of your activity. However, it seems to me that it can be very confused with concepts of "spirit" existing in other religions and philosophies. 

Let's look at the definitions we have:

The conscious unity of consciousness that has all potentialities but  no mass, no wavelength, and no location.

The Thetan (spirit) is described as having no mass, no wavelength, no energy, and no time or location in space except by
         consideration or postulate. Spirit is not a thing. He is the creator of things.

Ultimately, what is this thing called thetan? It is simply YOU before you have created an image of yourself and that is
         the most useful definition I know.    

What does this mean? It simply means that your identification with something material, whether it is even the most diaphanous energy, is not a thetan.

In all religions and mysticisms this happens: the spirit is identified with something material.

Although terms such as "diaphanous", "ethereal", etc. are used, all these are elements of the physical universe and therefore is not a thetan.

The total inability of the human being to confront the void, leads him to always try to associate something physical with the spirit. And even worse, for himself, it is very difficult to just "be" without creating an image of himself.

The thetan is a creator and, by its need to "have", it often appears to us "wrapped" in creations, images, ridges, etc. We give this the general name of "masses." But let's not confuse this with the thetan itself.

The thetan is only what observes and decides. It is difficult, until you reach the highest levels of the bridge, to conceive that something that has no form, without energy or mass and without any mechanism, can be something so powerful. 

THE HUMAN BEING

In order for a thetan to truly assume an identity, it will have to see things from the point of view of something in the universe in which it wants to move.

A thetan can thus assume itself at a certain point and observe from there.

The most common case is to take a point of view on a body in the physical universe to be able to interact with others and with the Universe.

But the state of the human being is artificial, the thetan using the body for its own pleasure and convenience. A thetan, after having done so, usually forgets it and, in order to increase its degree of unpredictability, suppresses the fact that it is separate from the body, but all it will ever be, is a thetan.

 

THE OPERATING THETAN

There are several degrees of operation of a Thetan.

What we call the operant thetan (OT) is a thetan, which may or may not have a body, but which is external to it, and which does not need it to control or deal with thought, life, matter, energy, space and time.

It can operate totally independent of the body whether it has one or not. He is now himself, not dependent on the universe around him.

Operant means "able to operate without depending on other things" and thetan is the Greek letter theta (q), which the Greeks used to represent "thought" or perhaps "spirit", to which was added an "n" to turn it into a new noun.
