It will be found that when an auditor obtains a floating needle (F/N) on locks without erasing the basic on the chain that the manifestation or somatics may recur in minutes, days or years. For they have only keyed out.
It is sometimes risky to audit past an F/N on the same chain. A Scientology auditor never would audit past an F/N. A Dianetic auditor has to recognize that the pc has only run a lock and ask for an earlier incident.
A floating needle is also obtained by erasure of the basic on a chain. That is the F/N one wants in Dianetics.
A floating needle is valid only between 2.0 and 3.0 Tone Arm position on a meter. Above or below that Tone Arm reading, the F/N is called an "ARC Break" needle.
A real F/N also carries with it GOOD INDICATORS. A cheerful happy pc.
When the Tone Arm is below 2.0, the incident chain has not been erased.
When the Tone Arm is above 3.0, erasure has not occurred.
When the Tone Arm is up at 4.4 the pc has made it more solid and has not erased the basic on the chain.
On the second time through, if the TA rises, you know there is an earlier incident.
The Dianetic Auditor is not concerned with "rehabilitation" of the overrun. In Dianetics it only means the engram chain is in restimulation and has not been erased.
When the basic erases, the TA will fall or rise to the area between 2.0 and 3.0 and the needle will F/N. One then stops promptly on that chain. He can reassess and run another chain now.
COGNITION means a pc origination indicating he has "Come to realize". It's a "What do you know. I …" statement.
Cognitions usually occur immediately after an erasure. They sometimes occur while running the chain. But when they occur with very good indicators the chain is almost always gone.
You can expect the rapid end sequence of (1) Erasure (2) F/N (3) Cognition in a well run Standard Dianetic session.
That's all you really need to know about it in Dianetics.
