Free Solo Processing is probably most safely done after the Upper Level OT7 (NOTs). Someone who has done OT3 can probably also do it.
Persons who has done OT3 or OT7 endlessly, may try Free Solo Processing instead. Many bigger Entities do not respond well to OT3 and/or OT7, if at all.
The more powerful Beings (Entities) has to be handled in another way. Penetrating the barrier and getting direct contact. Free Solo Processing does that. The make/break point here is if the Soloist can stand direct contact, and then still have enough free power to allow erasure. Direct Contact can be hell if one is not good at it and doesn't know the Basics well enough. As then it will pile up instead of erasing.
Luckily it can be done on a gradient. First the easier Entities, and as you are freed of them you get stronger and can handle the heavier ones and so on. No limit until Total Freedom is hopefully reached.
A few persons may not be able to stay on top of this stuff and get erasure, but may succumb to it and get sick. If you feel you can't handle this stuff, you should not continue with Free Solo Processing. Get out in real life and do something better.
Who can do it?
1. A new person with no prior training and processing: Only very able persons may have a chance. It may take a lot of persistence and interest to do it. A few may have a natural ability to do it easily.
2. A person with some processing and training and having done Lower Levels up to Grade I or II and maybe some engram running, may have a chance if he is able and interested enough.
Personally I would have skipped all Lower and Upper Levels if I had known Free Solo Processing 25 years ago. But that is me. Others may have it different.
Any attempt to do Free Solo Processing is entirely at your own risk and expense, if any. Accept that or don't start.
Children and persons with asthma or heart-problems etc. should not do Free Solo Processing. One often gets worse before one gets better, in Solo. So you need a safe margin. Only mature, healthy and able persons should do Free Solo Processing. And only if they really want to.
Trying to cure a sickness with Free Solo Processing is a sure way to fail. The roots usually goes too deep, taking too much time, and the goal of curing a sickness is too narrow a viewpoint to have any impact. My guess. So don't set up a shop with: "We cure all your problems and sicknesses, just buy our Free Solo Processing."
