NOT-IS-NESS
  1. trying to put out of existence by postulate or force something which one knows, priorly, exists. One is trying to talk against his own agreements and postulates with his new postulates, or is trying to spray down something with the force of other is-nesses in order to cause a cessation of the is-ness he objects to. (PXL, p. 64)
  2. not-is-ness is the effort to handle is-ness by reducing its condition through the use of force. It is an apparency and cannot entirely vanquish an is-ness. (PXL, p. 154)
  3. there are two different conditions of not-is-ness: one is just vanishment. The other one is an is-ness which somebody is trying to postulate out of existence by simply saying, "It isn't." A not-is-ness, in our terminology, would be this second specialized case of an individual trying to vanish something without taking responsibility for having created it. (PXL, p. 100)
  4. not-is-ness is manifested as and is in itself the mechanism we know as unreality. (PXL, p. 55)
