Yin-Yang chakra manipulation is the ability of a ninja to use specific characteristics of an element in their jutsu.
Yin is chakra that is in movement and yang is chakra that is at rest.
The idea is that the nin physically recomposes their chakra into the affinity they desire, then into that reserve of recomposed chakra they either add still chakra or they force more of their chakra through the reserve.
In terms of an example imagine, a wind tunnel on the top of the tunnel is a long slit and from that slit iron shavings are poured in.
In this case the wind tunnel is the recomposed chakra reserve of wind element and the iron shavings are more chakra being added to the reserve.
If the iron shavings are added slowly enough they get caught in the current of the wind being swept to the back of the tunnel.
However if forced through the slit fast enough they will form a wall that the wind will not pass through insulating the back of the tunnel from the wind.
Using this simple technique allows each of the elements to create interesting and diverse effects.
Pain is the embodiment of this effect because not only does each pain represent a chakra manipulation but also both the yin and yang of that recomposition.
During the Jiraiya Pain fight Jiraiya claimed Pain had "possessed all six different elemental chakra" (375.11).
However another translation of this page says he would "master the use of all six types of chakra nature manipulation."
The variations in translations leads me to believe they are both wrong.
What Jiraiya had been trying to say was that Pain had mastered all six basic types of chakra manipulation.
This meant that pain mastered the five elemental manipulations and spacial manipulation which I believe are the six base manipulations further reinforced by Kakashi who explained these things during Narutos training (314.11)(315.13).
Deva realm uses two abilities attraction and repulsion which the only elements that have these abilities would be Lightning and Wind.
Although Kakashi says there's no shock wave associated with the ability and if Wind was used there would have been, so Deva realm has a lightning affinity(421.13). Each pain is named after one of the realms of rebirth in buddhism these are Deva realm, Asura realm, Human realm, animal realm, Preta realm, and Naraka realm.
And they are ranked in that order from most enlightened to least enlightened which just like the five elements is a hierarchical relationship.
Asura are considered anti gods and Deva is considered a godlike state of being, so if god is lightning, then anti lightening would be wind.
Using this logic Human realm would be fire element but animal realm is the summoner or our spacial manipulation master so we skip her and Preta becomes water as Naraka becomes earth.
Knowing the elements of the realms and having a theory of how yin-yang manipulation worked I formulated a table to show the result of all the specific abilities created by this extra type of manipulation.
Manipulation-----Yin----------Yang
Lightening-------Attract------Repulse
Wind-------------Insulate----Conduct
Fire--------------Control------Eradicate
Water------------Diffuse------Suppress
Earth------------Composite---Reflect
Spacial----------Summon-----Seal
As you can see in the table earth yin creates a composite like effect where when added to a material it will increase the area of that material, this is how healing effects are created.
Naraka realm places his friends into the head and fills it with earth yin chakra filling in any missing pieces with his chakra and reforming them.
Yang earth chakra is a reflective effect that is why when Naraka grabs a victim they must lie to be killed by the jutsu, if they tell the truth there is nothing to reflect back on them and the jutsu ends.
Water yin chakra diffuses other chakra into it absorbing the effects, this is seen many times used by Preta realm.
Although he never uses the suppressive ability of water element that is possibly because he has no truly offencive ability and is weak to taijutsu making getting close to risky and absorbing chakra completely safe.
If he had known sage chakra was so dangerous before hand he may have simply suppressed Narutos sage chakra to avoid complications however he clearly states he did not realize that (435.06).
Fire yin chakra represents control because if you move a fuel through fire you can control where it will burn this is mainly associated with genjutsu however human realm also uses this to find everything he needs to know from inside Shizune's mind.
He then uses his Fire yang chakra to remove her life force and eradicate it ultimately killing her.
Asura realm isn't actually using wind element he just personifies it.
While based off an enemy from Jiraiya's past he is an actual puppet and uses no elements in his jutsu.
This is why in the beginning of the invasion he is on the distraction team and he only uses his explosives to draw a lot of attention more so than even the summons (419.01).
Pain even uses him as a body guard for Deva realm, he is simply an extra appendage to aid in his domination it's quite possible he is normally meant to cover Preta realm as he is weak to taijutsu.
Nagato is likely the actual wind element user, he is conducting his chakra through the air and into the receivers on the various realms as well as causing interference to insulate himself from having his exact location discovered.
Its possible Naruto could counter his insulation due to their sharing affinities and the sage chakra boosting his abilities.
So for cliff-notes:
1. Yin chakra is moving yang chakra is still
2. Pains bodies each represent an elemental recomposition and the summoning body represents spacial recomposition.
3. The table shows yin-yang manipulation effects on the basic chakra manipulations
4. I didn't actually use the buddha thing to get their affinities, my method was more complicated I happened upon this coincidence while trying to double check my ideas and it was a lot easier to explain.
