Self-Acceptance. The only true teaching is acceptance. All teachings ultimately point to this. The No Self Teaching is the biggest trap in Spirituality and is where 99.9% of seekers get stuck at. Many will never reach the ALL IS SELF awakening permanently because they are still stuck trying to rid themselves of ego. This is due to ignorance of what the ego is. The ego is a tool of expression of the Absolute. Without the ego an individuated expression is impossible. I'll use an analogy. Let's say you have an Orchestra, in an Orchestra there are instruments and each instrument has a part to play to make up the entire harmonious music. Without these instruments you couldn't have the Orchestra.
Well your ego is just an instrument, and the only issue is how skillfully were you playing the instrument. Many are too stuck blaming and demonizing their instrument instead of realizing that there was never anything wrong with the instrument but how you as the ABSOLUTE are playing it. When you demonize the ego you demonize your own creation, which as a result means you are demonizing THE SELF, THE ABSOLUTE, WHICH IS YOU!! This means you lack self love.
So what are all the components of ego?
Your ego is your language.
Your ego is your physical body.
Your ego is your self-image/psychological frame work.
Your ego is your entire memory of what you call your life.
If you ever truly lost your ego....it would be a TRUE REBIRTH but not one you would seriously entertain. Why? Because you would literally be a baby in an Adult body. You would need to relearn pretty much everything you ever learned. Language, how to walk, your personal history, etc. The ego is just a character that was created with certain strengths, weaknesses, and tendencies. Your job is just to learn about it, and be a good manager. 
For example if you know your body is allergic to certain things you don't consume those things. If your body needs a certain amount of sleep you give it that. The ego is just an instrument, no different than a car or a bicycle. Don't blame the ego for all your troubles, blame your lack of mastery. As the ABSOLUTE you are always in control of how you choose to manage and express your instrument, and Spirituality is just the remembrance that you are the player of the instrument not the instrument itself. 
 

Well, you're imagining it right now. See?
In order to speak at all about a thing called enlightenment, you gotta have a picture in your mind of what it is, and then you also gotta tell yourself that your picture is valid. Otherwise you could not speak about it or even know that you're enlightened. So enlightenment comes with many assumptions and ideas. For example, you tell yourself that you had an enlightened and you tell yourself that your enlightenment is complete and all there is to the matter. Or you tell yourself that your enlightenment is incomplete. Or you tell yourself that your enlightenment is the same as the Buddha's or Rupert Spira's, or whatever.

That existence is a more extreme thing than you dare to believe, that it is literally unbelievable that you are alive, that belief itself does not stretch high enough for the absolute ridiculousness and wonders of existence, this is simply because belief is a subset of knowledge and it can not circle itself.
I am incapable of believing that something like this world is real, it can only be known directly, our modern culture is an engagement in the delusion of reducing what is already given into a fantastical portion of itself.

Ok let me start.

(edit: added some more things which put a smile on my face)

I'd like to create (with your aid) a list of all known spiritual teachers who have lived and who are still alive. The individual styles of each teacher may not resonate with everybody, so the more teaching styles we can gather, the better. 
This list has no particular order and is not supposed to evaluate or rank the teacher.
Just write down whatever name comes to your mind, but please make sure not to repeat the name of a teacher.

Awakening is ego death- and coming back.  So when someone says you ain't awake - it means you ain't died.   It's Absolute and finally.  There are no degrees.  God is God and omniscience is Absolute.   There are no degrees to omniscience.   You can understand reality In a flash but you can forget it even quicker.  The fool believes there are degrees to grasping God.  There cannot be because God is beyond the human grasp.   There is only becoming God.  But enlightenment is very real, even if we are only left with the memory.   God becomes God for a short time - the rest of his time is spent being that which is other than God.  It's much more spellbinding.  To God, being God is boring.  It is much more enticing to be mortal.  

If you observe what is happening without labeling it, you'll see that it's is just a big spontaneous happening, which is exactly like imagination: spontaneous creativity without any true origin. From this perspective, it sounds more valid to say that everything is imaginary, because there is no true "ground" from which things are arising out from. But this is also just a linguistic preference. You could describe it as "groundless" or "empty" or "nothing", or choose to not describe it at all.
That said, if you want to start labeling what is happening, you can start to make distinctions between things like "real" and "not real". For example, people will often call something not real if it's not shared among other people. If you're seeing pink elephants and nobody else are, they will tell you that it's not real. This is in fact where you get concepts like objective/physical reality: there seems to be a shared underlying ground from which a great amount of things are arising out from. But the mistake would be to think that this "shared ground" is nothing more than a label, just like "real" and "people".
