questions to which, because of the characteristics of the mind, there is no possible answer. One of these is "Give me a n unknown time." As soon as the preclear starts to answer such a question, he has of course as-ised a certain amount of unknownness and will know the time. The answer to a fader question is measurable. However, it could be said arbitrarily to be answered when the preclearhasas-ised enough unknownness to give a known time. There are relatively few of these questions. —Creation of Human Ability Glossary (app 10.7.90)
