Hi @Eli, how is your friend going?
Just catching up with this thread, good on you for wanting to help him!
You can certainly ask Captain_Nemo or SammyG about that.
In this case, I would recommend trying the free Orgone Accumulator field with one or two other fields to address the brain itself.
(There are some excellent testimonials in that thread regarding motivation and it is a truly remarkable field for healing.)
If one is considering purchasing a field, Plasma Brain of Youth has significant rapid regeneration and healing potential.
So those can be paired together.
If it is an issue involving the brain significantly, they should help him.
Alternatively, Overcome Any Addiction: Dopamine Receptor Repair or Depression the Relief will repair some receptors in the brain and may help with motivation, and could be played in a short stack with the Orgone Accumulator if one isn’t utilising Plasma Brain of Youth.
The latter is a shorter audio if that is an issue given motivation. Plasma Brain of Youth is also rather short if this is an issue, approximately 4.5 minutes.
Others may have better suggestions but this is what comes to mind for a short stack to try.
Let us know how your friend is going in the threads for these fields if you like.
