Oh, this is an excellent video that, I’d say, truly gives an insight into what the Dzogchen Natural State is actually about … I’ve cobbled together the English as spoken by the Translator  present in the room with Tulku Urgyen, but it isn’t perfect and you may need to listen to it a few times (or more) to get the gist of it eh ?
“Free in the moment of seeing” means at the very moment of seeing your own nature, in this first and second instance, there is no thought. Thought has vanished.
Is there anything more fantastic than being totally free of thought ? Because there is nothing else in this world that can totally bring a halt to thinking … you can blow up nuclear bombs and use all different techniques but nothing really stops thoughts. But the very moment that you turn your attention towards your own mind, it is evident that it is simply an empty cognizance with no thing whatsoever. It is empty. But yet there is the seeing of that because mind is also cognizant. These are the primordial original unity that is empty and cognizant. But the thought happens we don’t believe that this is really “it” because it’s too easy. There is nothing more easy than this. Just like that. OK.
Don’t think of anything. Having totally abandoned thinker and what is thought of, at that moment you’re only seeing that there’s no thinker. It’s not something you gradually approach, like a spirit entering you. This is what is meant by the phrase, “one moment makes a difference, in one moment complete enlightenment”. That moment, like this (drops hand into lap), is the unmistaken Buddha mind. Don’t project outwardly, don’t concentrate inwardly, don’t keep a state in-between. Totally give up any mental effort. (pause) This is what (Buddhist teacher?) called utterly, sheer emptiness. You don’t need to block your five senses, not at all. Like this, but just remaining like this, everything is vividly experienced. But when you start to investigate a label, you’re involved in thought. This is what Padmasambhava says in the seven-fold supplication, “No matter what appears to your inner realm, in the field of your vision, before your eyes, the world, the beings, and so forth, even though experienced, just let it be without any fixation, in other words, “disown” everything. The dissolving of subject and object is the pure form of the Deity”. Whatever moves or occurs in the realm of your ears, any sound, or the sounding, whether pleasant or unpleasant, just let be in the continuity of sound being emptiness, because no matter what the sounds, in your hearing, is indivisible from emptiness — the empty resounding beyond arising and ceasing is the voice of the Victorious Ones. Do not get involved in concepts, leading or following. By leaving your thinking to itself, it dissolves naturally  into Dharmakaya. Thinking means our thoughts of this and that, if you just let it be, it naturally dissolves.
So true wakefulness, don’t do anything to it, accept or reject, hope or fear, then it’s enough. That is sufficient. So what you naturally need to train in, is to not imagine something by an act of meditating but also not to be distracted for even a second. Being distracted is the same as forgetting, and it is said “on the path of distraction, the demons lie in ambush”. The moment you look towards and acknowledge empty cognizance, that is called “having recognized”. Then there is the continuity of empty cognizance which you don’t need to fabricate in any way, just don’t forget it. Once you forget and start to think, then the continuity is lost. The moment you look, the empty cognizance is seen, recognized. And then allow the continuity of this seeing to continue, be sustained, but automatically . Then for the ordinary person, again a thought occurs. Then you remember, “Oh, I forgot”. Then again acknowledge there or notice, “Who forgot?” and simply recognize again and again you arrive back in this state of recognizing your natural face. That doesn’t mean sitting and straining, trying not to be distracted. It’s like ringing the bell once, and the sound continues, it doesn’t mean ringing the bell continuously. Once the continuity fades, that means we start forgetting, and we get involved in thought. Then again, we notice, “Oh, I forgot, I got carried away”. Then, alright, then look towards (your own mind), and again you are back recognizing. And again there is a natural stability in a continuous state of empty cognizance.
You need to train in that, short moments, many times. We have learned to live this life through training. We have learned how to behave, how to move about. We learn how to eat, (Translator states, “Oh, sorry, I got this wrong”). We have to train while involved in all the activities of this life, for example, while eating, you taste the food, and you start to think about the food, then notice, “Oh, I got carried away”. Again, recognize, while eating. At that moment, you will arrive back, vividly, in the state of the essence. You forget again, get lost, while walking about, moving in your room, you can still recognize Buddha nature when you lie down to sleep. If you’re diligent also recognize again. Actually, there is no time when you are not allowed to recognize the nature of mind, even when you sit on the loo. It is said like this, that the naked state of Dharmadhatu is unimaginable, relax in the impeccable state of awareness . If a thought occurs, it arises from yourself, it dissolves back into yourself. Any thought that occurs is your own expression, comes out of your own essence. It is only when forgetting the essence that the expression takes the form of a thought. But the moment you recognize your own expression, that it arises out of yourself and dissolves back into yourself, meaning into the “expanse of the essence”, this is what you need to train in, to become used to. There is no other meditation object or act apart from that. Not as much as a dust mote even. But if you forget or get distracted, we’re involved in thoughts. So please train in this. That is the practice. This is what the Buddha taught in the past. So here today, he has nothing to say besides this.

 Here what is required is the Observing of the arising of thoughts ?
 Inasmuch as Effort is required until it isn’t ?
 Or perhaps “Relax into … ever more deeply” ?
Therefore, what I’m suggesting is, with some luck, you’ll come to see HOW there is no actual “thinker”, thus you’ll disidentify from them (thoughts) and be released from the Yoke of a supposed Thinker eh ? 😉
