When a student’s pc develops a dirty needle (dn) it is caused by one of three things.

1. The student’s TRs are bad.

2. The student is breaking the Auditor’s Code.

3. The pc has withholds (w/hs) he does not wish known.

The remedy for TRs is to have the student do them in clay, showing the lines and actions of each TR. And to do more TRs with a fellow student.

The remedy for Code Breaks is to have the student define and do Invalidation and Evaluation in clay. And to list examples of possible upsets caused by each line of the Code.

The remedy for the pc with withholds is to send to a Scientology Review Auditor as Scientology can handle outnesses which occur in Dianetic sessions.

It is a safe rule in any event when a “dirty needle” occurs to send the preclear to a Scientology Review Auditor.

It is also a safe rule to assume that the student whose pcs get dirty needles is deficient on TRs and the Auditor’s Code.
