Heidegger didn't get it wrong. I have made what I call the 'Leap' into Be-ing my 'self'.
That being said, the purpose of this post is to let you know that just because the vast majority of people (99.999% of them) haven't done the work to "unify the self" doesn't mean that Heidegger got it wrong. And, just because the 'representations' (in the quote below) are the accepted representations of what we are talking about doesn't mean the 'representations' got it right either.
Actually, the 'representations' are part of the “Illusion of Self” you mentioned.
Esoterically speaking there are just two ways to go
(1) Reification of "self" as Dasein by living "authentically"(Heidegger) or striving for "Higher Self" ( Gurdjieff and Theosophosists)
(2) Dissipation of "self" as in Buddhist recognition of moksha or release from the "illusion of self" as a separate entity. Krishnamurti is one example of a writer who argues that any form of "striving" is counter-productive to "enlightenment".
You could have used “Historically” instead of “Esoterically” in the quote above. Same thing.
There is no 'unification' of the "self", "Higher Self", or “Dissipation of “Self”. 'Unification', 'Higher', and 'Dissipation' are theoretical misrepresentations
of what happens. What really happens is different than the theory and if you don't 'do the work' 'theory' is all you'll have. Typically, I have found that when people are 'theoretically representing', it's because they don't know what they are talking about (they haven't accomplished what they are theorizing about). The interesting thing is that because “making the 'Leap' into Be-ing my 'self'” is a rare occurrence we tend to believe the theoretical representations and not the one who has made the 'Leap'.
Ever since the moment you were born you have been projecting 'you' on to the 'world'. 'You' and (just about) everybody around you have been representing your 'self' according to the reflections of your projecting, i.e., you have used the world to define 'you'. You have turned your 'self' into a thing of this world
. The “illusion of self” is a function of you using the measurable, definable world to define you.
Who you are lives alongside of the world, you are not a measurable, definable part of it. Let me caution you here. If you have spent 10 to 70 years defining your 'self' as a thing, your 'survival' in (getting along with) the world and with the 'they' is in jeopardy. If the world and the 'they are defined by 'thing-ness' and you dare to be 'you', there will be a price to be paid. Don't kid your 'self' about it.
'You' (Self) are already whole and complete just the way you are. You just misrepresent your 'self' as a thing of this world. Your job, (if you choose to accept it, Mr. Phelps) is to dismantle the measurable, definable world and uncover who 'you' are.
Historically, what I'm talking about has been misrepresented by you, by the 'authorities' in the quote (above) and many others. Again, what they stated are misrepresentations, their misrepresentations are not what actually happens.
Go back and read the post on death I wrote. Try to put aside your representations of what you wrote in the quote above and you might
see that what I said 'covers all of the bases' of what you wrote. It's just that what I wrote doesn't represent your expectations of what you wrote.
Krishnamurti was accurate, "striving" towards a concept of 'enlightenment' is counter-productive. You are already enlightened and 'striving' takes you farther and farther away from 'you' Be-ing 'you'. All you have to do is dismantle the 'illusion' of the world to uncover that you are already enlightened.
It has taken me almost 62 years to dismantle the illusion of the world and uncover my 'self'. During that time I read Gurdjieff and just about every philosopher out there. I did the “striving for enlightenment” by trying to fit my 'self' into the representations I read (just like you).
As you read this you can 'know' what I'm saying. However, in the next instant you can doubt your 'self' and request proof. What I have posted is 'knowable' and not 'provable'. Trust your 'self', knowing.
If your proclivity is to argue with me about why
what I've said doesn't fit your expectations/representations you've already lost.
This is what Krishnamurti meant by "striving" is counter-productive to "enlightenment".
What I've accomplished can't be taken away from me and only I can cover it up again. I have found that once you 'make the 'leap', you have to keep 'making the leap' (diligence). It is not a goal to reach, it is not the 'end' of a journey, it is a way of living, it is who 'you' are. Every moment, you
make the choice to misrepresent your 'self' as a 'thing' of this world to get along (inauthentic) or you can keep dismantling the world and allow 'you' to 'show up' (authentic).
One last thing, if you don't want to do the 'work' I've mentioned, you will find a way to cover up what you've read here. You will use the 'authorities' misrepresentations to justify not trusting your 'self' to know what I am talking about. Eventually, you'll bury what I've said and you won't read anything posted by Dasein.
That's just the way it is.
