Ok, I try. But be aware this is extremely difficult to do it in a monological form via text, and hardly complete. Good news is: At that stage the path shows itself to itself if one just continues with the right meditation/awareness techniques. The illusion-mechanisms pop up one by one. If applying a good understanding of what will show up, the process can be fastened. It is like adding a blow-torch to the burning down of the illusion-building. So, here we go: Any thought implying I/me. "I-feeling" any understanding you have ("I" understand) any doubt ("I" doubt) all of it very subtle and fast forms of feeling separate. Or thinking that. Very fast & very subtle. Way faster than a thought elaborated over several second. Tenths/fractions of a second... Speed of awareness is crucial, that is being trained here And strength of awareness, to be able to also cut off core separate-self identities and suffering/resistance. Reckognizing that, not getting hypnotized by that, cutting it off by looking into its nature (empty consciousness). and since its very hard to tell the difference if a thought-arising is laced with individuality/separation/identity: Cutting off all of them, just for training. Yet, one can at other times also maintain ones awareness during practical daily life/thoughts. And memory of the past: It is being imagined right now, appears as complete "chunk" out of Infinite Consciousness/Being, and then gets elaborated in thought (which is very slow compared to how it emerges "fully" formed. That is truly a mindf*** when your awareness gets fast enough to spot for the first time how the complete past emerges immediately as "whole block" and then is slowly elaborated, fooling one to believe one is that "I" having this memory and thoughts. You see then how each any anything is just emerging to fool oneself. That is an aspect that Leo emphasizes with his concept of God-Realization. The past is radically imagined right now, there is no past. There is only an Infinite Formless eternal "Field" modulating itself to give the appearance of a past. Same for the "future". You don't have a past, You are an Infinite Vastness that is able to make up the past on the fly, and then have thoughts/feelings-arisings that "believe" that. Yet, that Infinite Vastness/Being CAN UNDERSTAND, and so it can understand that the past is imagined on the fly here and now. That is a major understanding/building block of Enlightenment, or seeing that separation from it all (separate self) is just an imagined arising within oneself. One is not a human, but the Infinite Vastness/Being (which is luckily also always here, aka immortal/eternal, can't go anywhere infinite Nothingness with nothing outside of it) imagining a human and all its elements moving/appearing within itself. So it is Duality gone (visual field nondual) -> Nondual boundless infinite (boundary of the field is gone) -> Infinite solidity of "external" visual field is gone, replacing solidity with mere groundless lucid appearance -> imagined illusion/lucidity/non-material, mere imagined empty hologram like appearance. time is gone (as described above, past imagined right now) -> always here, never not here Infinite Mind/Being. Eternal, immortal, absolutely fundamental, all is appearing and arising in it, always. space is gone (imagined IN the infinte vastness of True Being) -> space doesnt exist outside, space is imagined in oneself, the vastness of Infinity (which is not 3d space), and there is no 3D-space (or any space at all, non-euclidian, 4D, whatever) possibly existing outside of your Infinite Being. No outside. Infinite. All there is. Space is not self-existing outside of ones own nondual infinite being. It is imagined by it. What is behind your face? "beyond" the visual field. Not (3d-)space, but the Infinite (Being). -> spaceless, dimensionless, infinite. Containing all possible dimensions and realms, high and low. all of that is imagined/constructed/manifested right here right now in ones nondual True eternal Being, Infinite Consciousness/Being. -> A mirage/illusion appearing in ones Infinite Being, giving rise to the illusion of a human life within it. Another way to say that is: In Pointing out the Great Way, Brown is one statement: If everything  (1) all appearance of the world/visual field is seen as mere appearance (empty) hovering lucid and hologram like in Infinite Vastness (that can still be stage 3&4 Thisdell with separate-self well and alive, and that is why that is accesible via psychedelics) AND (2) each and any thought/feeling arising/"internal" mindstream event (including everything one believed oneself to be, I-feeling, I-thoughts, the whole history, the whole asking what is Reality/True Being, ALL of it) is seen as empty arising in Infinite Being/Nothingness/Consciousness. which means that ones mindstream is then conforming to the enlighened mindstream, or close to how Infinite Reality really is. Then Enlightenment can happen. But it can't be forced, since that would be thoughts with a thinker identified with them, with I-feelings, wanting something. Infinite Being/Consciousness has to understand itself, with no artifical activity/separate self trying to force it. At that point, the properties of the mindstream above can be automized, and this automatic meditation/mindfulness can be protected ("mindfulness without [artificial activity]"), element (1) of Nonmeditation Yoga, see Pointing out the Great Way, Brown).  One doesnt't focus on anything (which Daniel Brown calls particularizing). This picking out something specific with attention (particularizing, the fastest process of the mind, way faster than thinking) is what creates Duality, or better disrupts the original nonduality. Instead, one watches how particularization happens, and transcends that in a way that the boundless nondual unity with/of the visual field is not interrupted. Element (2) of Nonmeditation Yoga, "do not take to mind". and then maintains and waits in that state. Meditation and Mindfulness in these awakened nondual states does itself. Enlightenment can't be forced, because who would do the forcing? Instead, the Infinite Vastness/Being can understand/realize itself (or its True Nature) when conditions are exactly right. That is then Enlightenment. Bye bye illusion-human, hello Infinite Being/Reality "having" a human,. Making the mindstream conform to the enlightened mindstream so that Enlightenment can happen is very important, because that part can  be done by intelligent and informed practice. And that is why an efficient system is way faster, more efficient for most than and way more pleasent than a brute force approach like sitting an staring at the wall (brute force method), concentration or Koan-style. more likely to work than betting on just by having the right Karma and enough of the mere-appearance-infinite-character of the visual field and thought/feeling space in place already (Ramana, Anamanda Ma), and then some contemplation based on the already very much conforming mindstream Only those who needed to walked the steps can tell about the steps. Those are on top can mainly tell about how the properties of the roof are/what Truth is, but its more difficult to talk about steps that didn't have to be taken/climbed because they were already in place. The low success rate of the Enlightenment-endeavours in my perspective is due to mostly using brute-force-methods (which need lots and lots of willpower and pushing through negative emotions on the pillow) with no clear map of the steps of the path and the lots of cul-de-sacs of the path, or prodigy-approaches of telling about nature of True Being, but not offering a method path for average-gifted persons (Ramana for example). So, conforming to the enlightened mindstream mainly is: (1) Visual Field nondual, mere appearance, "hovering" in Infinite Vasteness/Infinity, being manifested/imagined right now (2) every thought arising/feeling arising is seen as emerging out of True Being/consciousness, made out of it, moving in it. Especially all thoughts/feelings relating to I/me. Feels impersonal, no separate indiduality found in any of that. And based on that the separate self (what one thought oneself to be) can be realized as mere flow of colours/appearances/feelings/thoughts (which have a very coherent and well made structure/Gestalt, and therefor are extremly hypnotizing and seem believeable) appearing in Oneself (Infinite Being), including the whole past, and that one IS the always here Infinite Eternal Field of Being/Consciousness. And the former separate-self is like the tree-picture in this wikipedia-article (below): A representation for something that appears (the tree), but has no independend existence apart from True Being (which is the nondual infinite eternal vastness of Being right here and now, with the body and mindstream having no different priority or separation from all that is). A well made illusion. The picture of the tree concept doesn't point to a real tree outside of consciousness (an object), but to shapes/colours of an imagined trees within Infinite Consciousness, not to real trees that exist outside of Infinite Being, self-existing/indepdently existing outside of consciousness. There are no trees, just the concept of them, and some imagined colours/forms/sensations giving the Gestalt of an appearance of atree. Same way, there is no human/separate-self beyond the appearance-Gestalt, and the concept pointing to such an imagined self-existing entity. There is only Infinite Being, not the human (which only appears in Infinite Being). https://en.wikipedia.org/wiki/Concept There always ever was, is and can be the Totality of (true) Being, self-aware, perceptions perceiving themselves. Either with reflective-self-consciousness arising (like normal human mind stream), or just mere awareness of the Totality without the self-consciousness part, perceptions perceiving themselves. Aware, but not separate. The non reflective-pure awareness of this vast field/being is more fundamental than the temporary appearing self-consciousness (with I-feelings I-thoughts). The Awareness is the Sun, the reflective (self-) consciousness (I-feeling, I-thoughts) is the reflected light of the Sun on the planets. Basically, its replacing ones old mistaken identity (imagined false illusion separate-self) with the correct identity, Infinite timeless/eternal (always here) Being. The flow of the human mindstream with its practical thoughts and so on happen within Ones True Being. One has a human, but is not only the human. Thoughts or feelings of separation are known to be illusion. When that shift happen, this realization is always available by just reaching out, or immediately always present. The visual field IS mere appearance and lucid/hologram/groundless, it IS infinite, eternal always here. Thoughts and feelings ARE just floating in it, made out of it, and "it" is onself, nondual. And that can be felt all the time or by just checking/moving attention there. It can never really be unseen. Reality/True Being understands itself. It is beyond doubt, unshakable, deathless/immortal always here. And that is the kicker: One/True Being is literally immortal and infinite. Not the ego, but True Being with its nature of Awareness. One can never die, and nothing outside one self can truly threaten one, because there is no outside of oneself. Seriousness and danger is replaced with laughter and security. Resting in True Being generates bliss, even when approaching it in Thisdells stage 4. Its a self-reinforcing positive feedback loop: Cutting off thoughts, field nondual, bliss flows. Literally. And that reinforces the stability of Nondual mere appearance visual field even more. Awakening enchances awakening. Suffering/resistance to what is no longer grips in any form since a long time. If it moves within ones being, is seen and let go. Would the inherent bliss of True Being ever be exchanged with grasping for being an ET seeing more of manifested reality, but suffers because its not enlightened? (more on that later).   That is a "hard" shift, it is not just thinking differently. It is for sure not "I am God and imagine all reality", which is just cosplay. It is Reality understanding itself, Infinite Being waking up to itself. What can do the understanding of that? Reality/Being/Infinite Consciousness. Waking up to its True Nature. That last shift is knowing what one really is, and that understanding/realization runs over a short period of time. Waking up. Happens only once. And is final. Is beyond doubt (since these would only be more thoughts/arisings moving within Reality and subsiding into it). The shifts/Awakenings leading towards it go over a longer time, many years.   And then of course there are infinite forms of manifestation, ET n+1, with vastly more understanding of the relative manifestations, basking in their understanding of the imagination process, different dimensions, higher realms, non-euclidian space, completely other alien manifestation realms. Humans look like ants compared to that for sure. These beings have been reported since millenia, in all cultures, all times. Reality-creating and maintaining Gods (Brahman, Shiva, Vishnu and endless other names for them). But it is the same True YOU, the only Being or Awareness in existence. The same being. There is nothing outside of it. No other (being, God, alien). And one can have an unenlightened ET, not having realized what Reality really is. Beings of higher realms are not necessarily enlightened. That tale is as old as the spiritual traditions. Although many of these beings of higher planes are enlightened. An unenlightened ET (which by definition has separate-self-elements not transcended/seen through in real time, which are by definition nothing other than the elements resisting the now, or suffering in other words) is a rather sad and suffering figure compared to a being who has realized its True Infinite Being. Calling the lower higher, and the higher lower. Whose modus operandi is that again? But lets not end too serious: It is all an illusion-game, "nobody" really gets lost forever, and Maya smiles lovingly on all not-really-(self)-existing-but-just-appearing children of Reality, humans and ETs alike. Although it can appear & feel very real & serious. Selling Water by the River
