Addendum:

I can also mention here that when it comes to the brain as an organ, the elimination process is truly elusive. Elements that do cross the blood-brain barrier can many a time be immediately felt, detected or perhaps “perceived”. However, when it comes to leaving the universe of the brain the process is fully inverted, more than most organs it takes the longest to rid of the brain of contaminants. That is the case even on the physical level, and disproportionately long after their effects on the individual are felt or instrumentally measured presence can be detected.

Physical elimination when it comes to the brain is almost unrelated to the mento-physiological one. Once exposed to certain elements, the subtle effects it seems can go on for months, years and even additional lifetime(s). So apparently exposure within the brain, be it in the form of elements small enough or naturally or otherwise coded to cross over into its region or other subtle influences afforded through the sense become like dye on fabric.

For those who fully consider reincarnation, dependency and other addictive personality issues are likely to have started in previous birth(s) where they are rooted. And, in part that is because physical elements also have subtle counterparts, as much as memory thought forms or traces.  When looked at from this angle, one may need to come clean or come undone, because, in the final analysis, it’s about the resultant long-term effect on the psychic abilities, in a way, I’d term it psychic sobriety.
