While being on NOTS, one should not do other grades, rundowns or other auditing. Exceptions are some assists. After that the demons are easier to handle. A similar procedure can be used for handling things that won't talk back. Problems with chronic somatics may be handled by finding missed demons, such as invisible ones.
Demons can also suppress others.
Discussing attention put to one's body and outside it. Invisible demons trying to get attention may draw a person down to their level. The invisible demons trying to get attention have to use pictures and mass. This is also an explanation for life, why thetans use bodies, because they need attention. The central tenet of acknowledgement in Scientology works because it's about attention.
