user-1: Further to the answers to this question, I want to understand what literally is 'see things as they are' or as the sutta states, Yathā-bhūta-ñāna-dassana. 
My questions are,

I understand that if I am looking at a beautiful woman, I am obviously not seeing as she is, but what when I am looking at a clear blue sky, not clouded by ignorance, lust, and greed, am I seeing things as they are? Or I should necessarily have to have insight into Three marks of existencece? Can I see things as they are without Enlightenment? 
If so, can only an enlightened being see things as they are?
Sometimes when we look at a flower we can see something transcendental, something which is greater than the sum of the parts. (Not a concept from Buddhism) but some people have an aura around them, even the Buddha in pictures is shown with an aura around His head. So does seeing this metaphysical reality constitute seeing thins as they are? 


user13589: It is not ''to see things as they really are'', contrary to the stock translation.
it is:

once you want to stop experiencing once and for all misery,
to see once and for all ''how things arise and go away''
which means to see once and for all they are mediocre, pathetic and unreliable, ie dukkha
which means seeing once and for all they are not ''I nor mine'', ie not your business not your story, ie anatta
which means experiencing once and for all dissatisfaction with them and not to even touch them
which means experiencing once and for all disinterest with them
which means nirvana.

The first step to be sucked into this spiral is

to ''''''''be moral'''''' like some puthujjana say, meaning not causing drama over mundanities with other people until you have no regrets nor remorse nor worry about their mundane activities,
once there is no worry over the mundane activities created and cared by those people, you are left alone to have time to experience the ''tireless energy'' and joy of the jhanas,
once there is this joy, energy, relaxation, you become concentrated and have most of the ''''seven factors of Enlightenment''''''
which I copy paste here


** - Mindfulness (sati).  
 - Investigation of the nature of reality (dhamma vicaya).**
 - Energy (viriya) also determination
 - Joy or rapture (pīti)
 - Relaxation or tranquility (passaddhi) 
 - Concentration, clear awareness (samādhi)  
 - Equanimity (upekkha).


Now to get to the point of no return, you must develop the first two, otherwise you are stuck at the jahnas like the hindus. 
It turns  out what remains is precisely remembering the doctrine and investigating it, which exactly means the first list above:

once you want to stop experiencing once and for all misery,
to see once and for all ''how things arise and go away''
which means to see once and for all they are mediocre, pathetic and unreliable, ie dukkha
which means seeing once and for all they are not ''I nor mine'', ie not your business not your story, ie anatta

user10100: You know black hole because you fluently understand the knowledge of the relation of physical&chemical properties about black hole. It doesn't mean you have seen black hole.
"Seeing things as they are" is the same. You know their paṭiccasamuppāda (causes) in every time before you know them (effects) directly.
You think some one mad because of their properties, so you never think the dead body is mad. The same way, the practitioner think clinging-aggregates are "impermanent, suffering, anattā" because they aggregates depending on clinging-paṭiccasamuppāda. So, without paṭiccasamuppāda 12, the practitioner can not see impermanent-characteristic, suffering-characteristic, anattā-characteristic"  of "impermanent-aggregates, suffering-aggregates, anattā-aggregates".
This is the reason why the practitioner can meditate sammasana-ñāṇa(realizing everything have 3 characteristics) after paccayapariggahañāṇa (realizing paṭiccasamuppāda/paṭṭhāna).
So, to practice "Seeing things as they are", you have to practice to see everything in paṭiccasamuppāda style. But before that step, you have to make sure that you having good enough adhi-sīla & adhi-samādhi (sīlavisuddhi&cittavisuddhi).
See, KN Paṭisambhidāmagga Dhammaṭṭhitiñāṇaniddesa & Visuddhimagga Paccayapariggahañāṇaniddesa. Both path of them describing yathābhūtañāṇa, directly:


The knowledge that has been established by the overcoming of doubt about 
  the three periods of time by discerning the conditions (paccayapariggaha[ñāṇa]) of
  mentality-materiality according to the various methods should be
  understood as “purification by overcoming doubt (kaṅkhāvitaraṇavisuddhi).” Other terms for it
  are “knowledge of the relations of states (dhammaṭṭhiti)” and “correct knowledge (yathābhūtañāṇa)” and “right vision (sammādassana).”
For this is said: “Understanding of discernment of conditions thus, ‘Ignorance is a condition, formations are conditionally arisen,
  and both these states are conditionally arisen,’ is knowledge of the
  causal relationship of states” (Paþis I 50). And: 

...
“When he brings to mind as impermanent, he correctly knows and sees
  the sign. Hence ‘right seeing’ is said. Thus, by inference from that,
  all formations are clearly seen as impermanent. Herein doubt is
  abandoned. When he brings to mind as painful, he correctly knows and
  sees occurrence. Hence ... When he brings to mind as not-self, he
  correctly knows and sees the sign and occurrence. Hence ‘right seeing’
  is said. Thus, by inference from that, all states are clearly seen as
  not-self. Herein doubt is abandoned.

user8157: Craving, delight & seductive qualities beguile the mind; including when seeing radiant monks & Buddhas. To see things as they are requires a pure mind without defilements; without craving. 
Its a chicken vs egg scenario. Enough defilements must be cleansed so seeing things as they are can put an end to defilements. 
,
Mentality ('nama') is just as or even more beguiling than physicality ('rupa'). For example, the so-called 'beauty' of a female form is more than mere physicality. The mind of the woman is also exuding an enticing quality. 
Thus, to see things as they are, both internal & external bodies & minds must be seen as merely that: mental (nama) elements & physical (rupa) elements. 
The elements are listed in MN 115. Viewing external objects as mere mentality phenomena (nama) and physical phenomena (rupa) is described in SN 12.19. 

user-1: You can see things as they are, everyone has direct perception, but it is typically rare in beginner's mind. Awareness of the delusion once the formation arises points consciousness directly at the seed of the manifestation, rather than the mind defilement itself that arises from it. Meditation and mindfulness train the mind to deliver wisdom (panna) of insight quick enough so one doesn't get caught in the defilement unknowingly.
See this explained here, from Thich Hnat Hanh - "Understanding Our Mind: 51 Verses on Buddhist Psychology": 

When seeds of consciousness manifest themselves in our mind
  consciousness, either we perceive them directly or we do not.
(...) 
The first field of perception is the perception of
  things-in-themselves, perceiving directly without distortion or
  delusions. This is the only one of the three modes of perception that
  is direct. This way of perceiving is in the realm of noumena, or
  suchness. Suchness (tathata) means “reality as it is.”
(...)
Are we capable of touching reality-in-itself? The Buddhist teachings
  say that we can. A flower can be the manifestation of the world of
  suchness, if we perceive it directly. It all depends on our mode of
  perception whether we touch the suchness of the flower or only an
  image of it that our minds have created. Our perceptions rarely reach
  the mode of things-in-themselves, however. We usually perceive things
  in the other two modes, as representations or mere images.
(...)
We are unable to reach the mode of perceiving
  things-as-they-are-inthemselves because our distorted image is a
  “representation,” not a direct perception.
(...)
The first five consciousnesses—the sense consciousnesses of eye, ear,
  nose, tongue, and body-are capable of touching the realm of
  things-inthemselves, especially when they contact their objects of
  perception without the participation and intervention of mind
  consciousness. When mind consciousness gets involved, however, there
  will always be some thinking and imagination, and the image brought to
  it by one of the sense consciousnesses will become distorted. (...) 
  Anything touched in the realm of
  things-inthemselves by a sense consciousness and then processed by
  mind consciousness becomes a representation. Yet even our mind
  consciousness can touch the realm of things-in-themselves from time to
  time. When we have a strong intuition, our mind consciousness is in
  touch with the realm of suchness. Intuition is a form of knowing that
  is not based in thinking and imagining.
(...)
We are capable of reaching the field of things-in-themselves, the
  world of suchness, but because we think and discriminate we don't
  usually perceive things as they truly are. The nature of our mind is
  obstructed (parikalpita). This means that we build a world full of
  illusion for ourselves because of the distorted way we perceive
  reality. Meditation is to look deeply in order to arrive at
  reality-first the reality of ourselves and then the reality of the
  world. To get to that reality, we have to let go of the images we
  create in our consciousness and our notions of self and other, inside
  and outside. Our practice is to correct this tendency to discriminate
  and think dualistically, so that reality will have a chance to reveal
  itself.

Note that this is Mahayana perspective.

user43: In my understanding of the explanations I received:
As many Buddhist concepts, "seeing things as they are" is a pointer to something happening in real life, but not necessarily in a sense we assume. Its meaning is more practical than strictly technical.
Most of the time we are "in our heads". We have so many preconceptions, thoughts, and inner chatter going on, that we can barely see what's going on in the real world. Instead, our vision is limited by our thoughts and preconceptions to such a degree that we barely notice things outside of our frame of reference. We tend to ignore them for two reasons: either 
A) in our frame of mind they are not cohesive phenomena, they seem illogical (because we don't understand their inner logic) - and so we tend to ignore them as noise, or
B) they go against our emotional attachment to some sort of theory or ideology, and so we semi-subconsciously dismiss them as fake / illusory / insignificant.
When we learn to suspend our judgement and lay aside our attachments and preconceptions (this is what Mahayana's realization of Emptiness entails in practice), and stop our never-ending inner-monologue, and lose solidity of this heap of overgeneralizations we call "ego" -- then and only then we start seeing things "as they are". 
In my experience with it, this vision liberated from preconceptions can be allegorically called "quantum" or "multidimensional". Because we are not limited to one theory and one interpretation of what's going on, we see them all, or rather, we directly see the entire "space of interpretations". There is an element of ambiguity, but it's not regular ambiguity which is hazy vision - instead it is a very clear kind of ambiguity.
It's a very practical, very direct kind of vision. We are simply not in our heads, are eyes are open and we really look around, and see things we have not seen before.
This is the critical point of the explanation.
And then on top of that, as we develop prajna, we begin to "see" "hidden connections" between things. These are not as much some magic properties as abstract relationships of (latent) influence and causation.
Combination of this "quantum" vision and seeing the latent influences is called "seeing things as they are" - in my understanding.
