I expect feelings to be exactly the same; there will still be both happiness and sadness but there will not be the suffering, because the feeling will just happen and will not happen to anybody. I imagine life to be more vibrant because instead of being identified with thoughts I could be completely immersed in life, in fact there is nobody being immersed but it is just being part of life. I see it as a releasing, fusional kind of movement.
We all have expectations regarding realization or clear seeing of no self. Still, everything happens how it happens, meaning that every expectation is a thought, and thoughts just happen. The thought, "I am identified with thought" may continue for some time. Yet, if really seen through, the knowledge of no self does seem to take the sting out of it... it becomes hard to believe any thought as an absolute or relative. Any kind of thought can happen.
In the beginning there may be thoughts that this is just an intellectual understanding, and that is just another thought. All understanding occurs in a timeless instant. When anything is understood, the understanding occurs instantaneously. All understanding is only actualized and known as an object of thought. Don't be fooled with this nonsense about non-intellectual understanding being different than an intellectual understanding, it is all rubbish. Any understanding that one has in this particular moment may be superseded by another understanding at any time.
That said though, there seems to be an aha moment of understanding that takes the energy out of seeking, and doubting.
Here at LU we are pointing to the undeniable fact that a self cannot be found. For something to be exist absolutely, it must not be changing, coming into appearance and dissolving away in time. The very nature of temporality, of any thing being temporary, means that the thing has a beginning, and end, in time. If it disappears, how can that be me, the knower of that changing sensory data. Whether it be a thought, feeling or primary sense datum, it is an object of knowledge, and as such, temporary. A thought is completely gone, destroyed, every moment of thought. How could I be a thought, or series of thought? I never have an experience of non existence.
There is nothing you can point to that is a findable candidate for a individual self. Please look directly into your experience now. See if you can find any candidate for a limited entity called a self. Describe that.
