A “dirty needle” indicates that a pc has withholds or is ARC Broken.
When a pc is to be audited on Dianetics as a student or org pc he/she usually goes to the Examiner after a Dn C/S I (training pc) is done.
If a DIRTY NEEDLE (ragged, jerky, ticking needle, not sweeping) is seen by the Examiner or the auditor the pc should have a Scientology Review before Dianetic auditing is begun with an order for “GF and pull all withholds”.
