Hello Eram,
Thankyou for your pragmatic observations. It is simple, theoretically. It is the mind/thoughts/ego which tries to complicate things. So in challenging the absolute reality of thoughts/beliefs we are in effect challenging the existence/reality of the ego. Those thoughts previously taken as "facts", which may result in suffering, are upon close examination found to be just thoughts, which need not be identified with (including the "I am the body" thought)
Katie's Work shares similarities with Buddha's four noble truths and Ramana's Self enquiry. Adyashanti was possibly referring to the increasingly complex systems of philosophy and religion which lead one further into the machinations of the mind, rather than the attainment of evanescence...

"Later Sri Bhagavan continued: The intricate maze of philosophy of different schools is said to clarify matters and reveal the Truth. But in fact they create confusion where no confusion need exist. To understand anything there must be the Self. The Self is obvious. Why not remain as the Self? What need to explain the non-self?" - Ramana Maharshi
Mr. W. J.: When we read about it we read it intellectually. But it is all too remote. When we see you in body we are brought nearer to Reality and it gives us courage to bring our knowledge into our everyday life. If one realised the Self and acted up to it in the West, one would be locked up in a lunatic asylum. (Laughter.)
M.: You will be locking yourself in. Because the world is mad, considers you mad. Where is the lunatic asylum if it is not within. You will not be in it, but it will be in you. (Laughter). Uncertainties, doubts and fears are natural to everyone until the Self is realised. They are inseparable from the ego, rather they are the ego.
D.: How are they to disappear?
M.: They are the ego. If the ego goes they go with it. The ego is itself unreal. What is the ego? Enquire. The body is insentient and cannot say ‘I’ . The Self is pure consciousness and non-dual. It cannot say ‘I’ . No one says, ‘I’ in sleep. What is the ego then? It is something intermediate between the inert body and the Self. It has no locus standi. If sought for it vanishes like a ghost. You see, a man imagines that there is something by his side in darkness; it may be some dark object. If he looks closely the ghost is not to be seen, but some dark object which he could identify as a tree or a post, etc. If he does not look closely the ghost strikes terror in the person. All that is required is only to look closely and the ghost vanishes. The ghost was never there. So also with the ego. It is an intangible link between the body and Pure Consciousness. It is not real. So long as one does not look closely it continues to give trouble. But when one looks for it, it is found not to exist. - Ramana Maharshi
You are making excellent progress Eram, and yes, lol, it does lead "somewhere"... beautiful beyond description;
With Love
