Negative energy compounds stuff and yes cleaning the aura/chakra of P, P, and F negative energies helps.
Past = From past lives leading up to Present life.
Present = From the time of cleaning currently
Future = Everything coming in is reduced. Negativity always exists i.e. clean minimum twice a day. But reality is as you build up the protection and cleaning you'll reduce negatives or keep negatives at bay on the aura just in time to clean off and slough off the dirt.
As well as take advantages of Witches Sabbaths either do a 7, 14, 21, or 28 day Purification ritual from a Saturday for up to 28 lunar count. If you fall on a continues streak i.e. the Friday or Saturday ends you can carry on another 28 days on top of that. Or do a 1-day General twofer working. You start at Nightfall of Friday and end on Afternoon of Saturday doing a 1-day purification ritual.
Technically you should go for up to a 28-day working to significantly purify the soul. But doing every Friday and Saturday the 1-day general working is fine.
What your talking about trauma is freed from a Munka, Ansuz, or Uruz working. You need an FTS or Freeing the Soul ritual.
You perform 40, 60, 88, or 108(108's only negative is it requires 40-days to complete minimum to actuate the 108 into the Soul). You eliminate negative karmic patterns and you slough off the trauma. You may require a 40-day minimum if the trauma is really bad do it for 90-days or 50 more days. You can do double i.e. 80 but why stop when you can carry on for 10 more days if you did 80, 10 more isn't gonna kill you.
You can also do another 40 at a later period of time or keep it at 90 and do another 90.
Most people probably need 40 days maybe a secondary working a few months later or the following year and their good. If they really wish to pound this negativity 90 then.
An affirmation would be akin to something like.
I am fully free from suppressed trauma, now and forever, in a fully positive, healthy, and best way for me. x9
9 = finality and permanence with an emphasize on endings.
So 108(or lower number) Ansuz, Uruz or Munka and then the affirmation x9s.
Visualization visualize chains and bindings hemp ropes and whatnot breaking off, falling down, wings bolting etc.etc.
I(you in question), Fully(one of the definitions of fully is 100%), suppressed trauma the subject in question and finally being fully 100% positive, healthy, and best for you. Now so it actuates immediately it's a little unnecessary as your speaking in present or perfect present tense but it's an action word and it's useful. Forever so it's kicked off your soul so you don't kaballatize realities again with this non-sense and repeat the karma the following life or in current life.
Best for me might not be best for you and vice-versa.
Sheer fact is this seems more like a generalized specific working. For example say you posses birth trauma from a bad birth and it actuated a effect on you.
Keep doing the general specific working as above. But later after you find another 40-day working you discover in time birthing caused issues.
So your following 40-day working for negative karma would be.
I am fully free from birth trauma, now and forever, in a fully positive, healthy, and best way for me. x9
BTW yes a general anti-karmic working might work a bit to uncover negative karma. But working specifically on one problem at a time is a more appropriate concrete working.
And yes if your wondering neutral and positive karma are good. Neutral isn't bad just okay. But negative karma or sins or evil is to be purged like negative energies, bindings, hatred, ill will, etc.etc. the bad stuff is to be sloughed off. As for Nadis Yoga doing Hatha for a long while purifies the Nadis. So as an accelerant you would perform Yoga and the buzz if you feel it during Savasana or corpse pose.
An affirmation would be something akin to:
All my Nadis are fully purified of dross, now and forever, in a fully positive, healthy, and best way for me. x9
All Nadis, 144,000(72,000 Male/72,000 Female) including Ida, Pingala, and Sushummna Nadis, EVERYTHING; ALL 144,000. Fully 100% purified of dross not cleaned no purified now and forever to clean your soul all done in fully positive, healthy, and best for you way.
As for visualization, imagine your Nadis imagine these tremendous amounts of fine veins of the soul attached to all chakras and especially the majority attached to the center manipura(gold chakra). visualize them with white light or white-gold light purified and free from dross spend like 15 seconds to a few minutes visualizing this purifying all this crap out of your soul.
So negative energies are Auric/Soul attachments; past lives, present life, incoming future. Negative Karma cannot be removed with cleaning but require mantra action to slough it off the soul which will increase virginity(i.e. clean/cleaner/purified soul) and on top of that you also need to perform Yoga to remove the dross from the Nadis. Only Yoga works on the Nadis it seems like negativity is the easiest to remove and the harder ones are mantra/yoga for nadis and negative karma.
With negative karma being the most annoying to remove.
The only other negative energies to remove are the chakra seeds and that requires Kundalini to burn it off to actuate the Spear of Destiny.
Anyways hope this helps.
