Master OZ, everything you said is true, I honestly agree with you. But let us face it,
all of this Nen thing is fiction. I really wish if all of it was real,
can you imagine how much damage a nen-user would do in real life 
. The Nen theory was carefully designed and presented, but,
keep in mind, Togashi , though a genius, isn't God.
This is what I understood about aura and how it works so far.
Aura has a distinct system such as that of the nerves; when you use "En", its like you extend your body and can know exactly what comes to your range. When you use "Zetsu", closing the nodes,
no one can see or feel you, you'll appear as a non-living object. If you imagine it as a part of your body, "Hatsu", "Ten" and "Ren" are also explainable.
"Gyou" and "In" remain a mystery.
I mean does "In" encode the rays that get reflected from the aura, and does "Gyou" decode it so that it could be seen by the ordinary eye.
But bringing science to this fiction is fuuuuun
All the more reasons to bring, to those who can´t grasp that, the same sense of dread of Nen users as I have.
I can´t tell whether he is a genius or not. They tend to lose on the methodical and execution side of things.
The problem is that it wasn´t elaborated upon at all. If aura indeed had such an inherent distinct system, then everyone would be aware of their aura. But they are not, therefore they need to undergo prayers and meditations to become "aware" of it. They must create this "aural" framework on their own so that they can feel the aura. (As a sidenote this makes me really wary of the whole external awakening as Wing does it. Not because Nen users would be in thousands instead of dozens

, but by external awakening Kilklua´s and Gon´s v aura is released without them having laid any aural framework at all.They would have been utterly exhausted or dead if it weren´t for plot reasons. Laying such aural framework during several seconds is absolutely out of question.)
In Zetsu you can be seen, but there is an underlying concept of "presence" in almost all of manga. People sensing presence of other people seemingly on some hunch is a feat many characters across many franchises exhibit (let´s not go there). In Zetsu in order to "feel" you, one would have to touch or go inside your body with En, as opposed to normal state when one can touch the aura leaking from you or your Ten to "feel" you.
This would be even more insane, because then you would need a specific Gyou to break specific In (which in all honesty would be even more awesome). So far there seems to be one general In, so there would have to be one general Gyou (but that actually shouldn´t be true).
I like that you posts are well thought out and that you spend your time analyzing Hxh sper cool.
But I must say yo canot re-write or write of piece of the manga as if you are the author. Ten is one technique why because Togashi said so..Not much to argue with there, it's ludicris to say nah that not what he meant or he's wrong. Unless he's breaking the code to his own work which he hasn't only a minor mess up with Kurapica's OPness.
Your looing into Nen pores too much when they haven't even be elaborated on or referred to in in depth knowledge.. Your ores can be forcefully open or in time you'll learn to open your pores to allow you to access Nen...Ren, Ten, Gyo, Hatsu are Nen principles.. That all have advanced forms such as Ryu, Ko, In, En
Conjurer's when explained about their training, need visual, texture, hygiene etc etc and other familiarities to conjure such an item.....Stop stressing your head over Atoms, Mass it won't work with the fictional...I'm juss happy somebody is able to take the fiction of HxH and have it be so relatable to real life.
How do the characters do Hatsu...Same way Kurapicka learnt to conjure a chain, They take the necessary steps into forming an personal ability that'll suit their fighting style or needs.. Remember Hatsu technique's are commonly mixed more than 1 category of nen..........Emisson is often coupled with manipulation. As is manipulation an conjuring
Actually that is not ludicrous at all, Togashi is a human, he can make mistakes, especially in a series minced with such breaks as this one.
I could agree with some things before THAT. They are clearly in a world similar to ours, Nen should be held to some Physics standards, especially if they are used as an in-universe explanation for conjuring namely and double especially if Nen is portraited not as a convenient magic (say Avada Kedavra, point the stick and it dies), but as a system feasible in magic realism POV.
Disagreed.
Think of it as it was the air on your body. Trough the skin, air goes in and out. Imagine that you could actually control the air that goes out of your body. THAT is Ten. Is not the opening of the pores, or to close it. It's just shaping it. Basic manipulation of it.
The opening of the pores is not a technique itself, it's the awakening. In that sense, Zetsu is more related to that action than Ten is.
For sure it's not always explained. But because it doesn't need to: It's stated that Nen works trough your emotions and vows as well. It's hard to imagine WHY that will empower your Hatsu. But it works like that. There is no need to ask yourself how it does that since the system is not yours to make :P
You will have to assume that you don't need to actually think on molecules when you conjure something, you just need to know how it feels and your brain (At least the unconscious part) works the other details.
When I say HOW I don't mean the technical part but how every character deals with their own energy. They have rites, peculiarities, way to act that endorses their techniques. Enhancement seems to be very limited on the things it can do, yet every Enhancer we have seen has a different technique and a different way to deal with their aura.
I don't know if I'm explaining myself correctly here >_>
About In...I think Togashi fucked that up, to be honest. In theory it works as a way to disguise the aura, but every situation regarding Gyo and In are quite confusing. I hope He fixes that later on.
Actually I wouldn´t mind that, but if Zetsu is explicitly stated as closing off the nodes, then logically there must be a technique to do the reverse of that, otherwise they would be always in Zetsu once activated for the first time. And what kind of technique is better suited to do that than Ten.
I didn´t mean that. I meant for example; Enhancers have the best offense, defense and healing abilities. How? How they bolster their defense and offense (as in are they making their aura denser, tougher...which wouldn´t make them special at all) and healing ability (destroying things is easy, but healing is incredibly hard - repairing, reconstructing, replacing tissue on a cellular level is in my honest opinion feat ever impossible for Gon and all healing is basically all that{so far all that seems to be on autopilot, so to say, which makes it all the more bull}). If we look at Nen without taking account any discussion at all, then at least 80% of all Nen activities occur automatically or subconsciously, which is a very far cry from the system Togashi intended to use - that is; clearly and openly defined aura system that has no contradictions, is complete and has no dependencies in the defining principles.
You do but it is the technical part that causes me headaches. With proper insight into these things we could properly appreciate or even discuss the pros, cons of these abilities. As of now you can´t really compare anything else outside Uvo´s Big Bang attack and Gon´s Rock and then only by the effects (explosions or damage) they cause. But with that insight one could compare cost of one Big Bang with cost of one Rock, how many of them can they do on one day, how efficient are they when creating said effects from their aura AND compare all of that to, let´s say Knuckle´s aibility or Paku´s ability.
