A practical explanation describing the cleansing of the taint from Saidan

Recommended Posts

Cleansing of Saidin
I have put a lot of thought into this abstract process and after reading and re-reading how Rand and Nyneave accomplished this feat I associated to one of the specialties in which I work. I am a registered nurse and have worked in hemodialysis which the process removes solute (substances) in the blood, water and other solutes in two ways that can be akin to the cleansing of Saidan. First, osmosis a passive phenomenon works is with the movement of water through semi-permeable membrane from a place with lower water content to a place of higher amount in the dialysate bath contains 2 grams of dextrose. Solutes also move by this method solutes move from a place of higher concentration to lower. Filtration is the main key to solute movement from a medium of higher concentration to a lower concentration also as pressure is applied to the fibers of a dialyzer forcing movement of water via pressure along with these solutes are dragged along with water removal. Think of a tea bag you want to get the rest of the tea out you either squeeze the bags with your fingers or while sitting of a spoon you wrap the string around the bag and spoon and pull thus adding pressure. Both processes are done through a semi-permeable membrane. Each dialyzer contains millions of hollow fibers with different pore sizes. The types of solutes are removed from the blood due to the small pore size thus not allowing blood components such as red blood cells from dialyzing out of the body through the dialyzer. 

Ok, getting to how Rand and Nyneave accomplished the cleansing based on Winter's Heart explaination we all know that the greatest feats among Aes Sedai occurred with both men and women occurred while they were linked in a circle. Rand’s action with the help of Saidar indeed exhibited how such feats resulted. Using the One Power, Rand’s formation of the tube of saidar acting as a conduit in confining and squeezing saidin while saidin pushed against saidar moving it by pressure through the flower he visualized forming of saidar acted as a semi-permeable membrane in which from Saidin the taint had to pass through the conduit of saidar. Based on the information from the chapter the conduit began from where Rand and Nyneave where and the Saidar. That's how Rand even conceptualized the abstractness of the process of using Saidar. 

So, when Saidar and Saidin where forced through the flower motif common to how female Aes Sedia describe the process of embracing Saidar Rand focused the conduit into the city of Shadar Logath and since the evil in the ruined city did not have the Dark One’s taint but another kind of evil regardless, the taint was in a sense dialyzed as waste into that city. Saidin and saidar unable to mix this we know however, saidar’s own immense power contained saidin within this conduit, and once Rand eventually felt the movement of the taint by continuing force of pushing saidin while reinforcing the tube of saidair which exerted against Saidin I believe that just as the male and female Aes Sedai made the eye of the world they may have used this same method however they lacked the protection of a terangreal like the access keys to the Choden Kal’s to buffer themselves resulting in their deaths upon creating to the taint free pure saidin at the Eye of the World. Further, since the evil of Dark One’s taint and the evil of the city of Shadar Logoth could not mix but repelled each other lead to the destruction of the city the example we have evidence in the response of Rand’s wounds in the way they react to each other and their action during the cleansing. One more thing the idea of using up saidin/saidar is not possible because the source was noted in Winter’s Heart coming from everywhere in creation even Shadar Logoth. So despite both evils being different and in a sense two different types of hateful evils obviously the build-up of these evils where responsible for destruction of that evil city when the taint was removed. This is proven in the last book a Memory of Light. This is how I conceptualized this process. For me this is the easiest way to understand and illustrate the cleansing of Saidan.

This is one of those deeper analyses that happens with a lot of other series and it attracts all the Eglio

er Elios and people but I think people assume in general WoT is fairly simple where I disagree completely


I think the series as a whole has a lo tof genuine subtext and things like this that might have real meaning

and interactions.


Admidttedly I'm not great at this  topic here but maybe if we encourage this then Wheel of Time can get a

kind of treatment of this sort.


For those wh who don't know there is 100% no Wheel of Time show happening... this is one of those hit jobs

byt the elite where they go oh we show interest but it's a red wedding and they're plan is just to get the original

peoiple involved invested and then suddenly it's in development heck for 10 years....


It's pretty awful really.


Although come to think of it now they might make one anyway just to ... you know once the Red wedding fails

have an actual wedding... kinda deal.


....yeah this is silly in some ways dangerous horrible but also and silly....


Where was I...


But yeah Wheel of Time isn't strong int he way GoT was... it feels like nothing is acceptable and it's all

bad because somehow it's older even though it predates Got by like 6-7 years...


But posts like this show me that people then or now haven't forgotten about it/and o/or still find it interesting

by moderns tandards and so I'm glad and hopefully people will analyze all things kinds of things like this.

I like it!! Even reading the Cleansing myself, it felt like a medical procedure being performed. It is really cool. Of course, I then went into the nuking theory, which re reading told me was wrong. Thanks for this!! No one has explained the Cleansing well, too many mathematicians here using equations that lost me.

I reread what else the cleansing involved and the transferring the taint into the city of Shardar Logoth though evil I think Rand was cleaver to do because of his wounds from Ishamael and Padan Fain. I believe either Samitsu or Flinn mentioning that the two evils were fighting each other. tWoTC notes that though they repelled each other they were attracted to each other in such a way that they couldn't mix I believe was the effect of the two destroyed the city. The effect in Rand without the healings done by Cadsuane, Samitsu, and Flinn (who actually sealed them of from each other though he said it was only temporary.) I It's also interesting how the Eye of the World was created and how as it was done during the breaking. One could only make assumptions here as both men and women Aes Sedai created it and many died in the process. Obviously, it was done in a circle but what was the method that resulted in the untainted pool of Saidin. I going to assume a woman was leading or the men were not affected fully by the taint. Lastly, was it done in the way a channeler is turned meaning the med channeled through the women filtering out the taint. Just some thoughts on the subject.
