In Scientology a high TA is always an overrun.
In Dianetics it means AN ENGRAM TOO LATE ON THE CHAIN TO ERASE IS IN RESTIMULATION.
A Scientology auditor “rehabs” overruns.
A Dianetic auditor cures high TA by finding what engram (lock or secondary) is in restimulation (active). This will show up as a PAIN, SENSATION, MISEMOTION OR OTHER PRESENT TIME FEELING the pc has. In short, just by finding the somatic by list and assessing for longest read and running R-3-R you can cure a high TA.
You handle a TA that goes up during a session by completing the chain exactly as in R-3-R.
The same action you do for R,3-R also cures the high TA.
By running a pc through only once each time instead of twice you leave a later incident too charged for the pc to see an earlier incident.
By trying to erase the somatic only, not the picture (”pc no longer has somatic”) you can leave the picture partially there.
There can be an infinity of wrong ways but only one right way and the right way is R-3-R by the book.
A high TA (4 or above) is simply the E-Meter’s reaction to increased mass. Mental Image Pictures have mass. The mass has what is called resistance to electricity. The E-Meter measures electrical resistance. Mass resists electricity. Thus in the presence of mental mass as contained in mental image pictures, the Tone Arm of the E-Meter rises.
When you restimulate an engram, the E-Meter current flow has more trouble getting through the pc and the TA rises.
When the engram (or lock or secondary) is “keyed out” (moved away) the TA comes down and the meter needle will float.
If you find a long chain with many engrams on it and run a late engram the TA goes up. As you go earlier, and eventually find Basic, the TA comes down and when you erase the basic engram the TA will come down to between 2 and 3 and the needle will float.
Old disproved theory pre-Dianetics was that the E-Meter reacted to sweat on the hands but of course a person would have to sweat and “unsweat” to make the meter behave as it does. And the idea of “unsweating” would be ridiculous. Palms of the hand do not go wet – dry with enough rapidity to account for meter reaction up and down.
When you run several engrams through once or several somatic chains without erasing any you pile up too much mass and the TA will go high and stick.
Even if nothing is done to repair this the pc will de-stimulate (the pictures will drop away) in from 3 to 10 days.
It is a very poor show of auditing to do R-3-R other than exactly by the book. It is very easy to do it exactly right. The drill is simple. If done exactly right the result is good and invariable.
