It is with Camalo's help that the magician becomes invisible, i. e. that he can betake himself into all spheres, mentally, astrally and, if necessary, also physically, without being recognized there. The faculty of making oneself invisible anywhere desired is quite a special faculty that is only controlled by a few magicians.
