I'm not saying that feelings don't exist, I'm saying that they're not real.
Of course you have thoughts and feelings, I'm saying that you are not your thoughts and feelings.
When someone becomes aware of that, it's a very subtle shift from being identified with feelings and thoughts to witnessing consciousness.
And it's not difficult at all.
Being identified is difficult. Because then you're right or left and you have conflicts, you have an opinion about everything, etc. etc. etc. etc.
They are not yours, they are largely collective and come from your upbringing and previous experiences and they are also culturally determined.
But you experience them and you are responsible for them. You can never blame the other for your feelings.
They are certainly not a good foundation to build something on. I am curious what you mean by that exactly.
The difficult thing about witness consciousness is that when you go into it, the consciousness sees everything that is in your system. So that all the feelings that you have put away, frozen energies that they wake up. And that is very uncomfortable in the beginning.
But then you no longer feed them, and they extinguish.
Now we live a life of consuming and numbing. Thinking is also numbing because you then produce all kinds of substances such as endorphins, gamma-aminobutyric acid and anandamide.
A nice movie to watch is The Shawshank Redemption. He is imprisoned with fellow prisoners. The others are used to prison and are someone there. An older man is released but he had become accustomed to prison. When he is released he cannot settle and commits suicide.
The main character however, does everything to get free when he notices that they want to keep him there forever.

It takes a lot of spirit (soul power) to crawl through such an enormously long, stinking sewer pipe full of nuts.
But then you are free!
