- that which one perceives by radiating towards an object and from the reflection perceiving various characteristics of the object such as size, odor, tactile, sound, color, etc. Certainty of perception is increased by drilling in certainties as above. Theta perception is dependent upon willingness to handle and to create space, energy and objects in view of the fact that the mest universe can be established easily to be an illusion. One must have an ability to perceive illusions before one can clearly perceive the mest universe. The thetan who cannot perceive the mest universe easily will also be found to be incapable of handling and orientating other kinds of illusions with certainty. Theta perception is also a direct index to responsibility, for responsibility is the willingness to handle force. (Scn 8-8008 Gloss)
