I am nowhere near close to that step, but I do feel in my own evolution small pieces of it coming together.
I will just say that as a Thelemite, each sephiroth and grade that you advance through, changes your baseline.
In this day and age, I personally believe the average person is barely on the Tree at all. They are right below Malkuth.
You could view this as a Student in the A.:.A.:. curriculum.
Anyway, we all bounce up and down the Tree in our daily lives, but our baseline frequency evolves through the Work.
Much like a rubber band can be bent or changed, but made tighter, although we may 'fall' or 'rise' , in 'tightening the band' through Work, our baseline frequency will raise in vibration, and therefore our 'home' Sephiroth can (generally) change to be 'better/higher'
The closer you get to your Higher Self , near Tiphareth, you find yourself subconsciously manifesting more harmony and compassion in your life.
This in my personal experience is not chosen, it just feels 'wrong' to be disharmonious.
We are all human, sometimes it's 'fun' to shout or judge people. But as you evolve you feel/know that it is not good for you, and is an indulgence and feels 'dirty.' But we all have sometimes automatic lizard reactions. As we evolve we can notice outside of ourselves, inwards, more and be more mindful at least while it happens.
I feel that this natural growing of a 'identification' or vibration with Harmony, is a baseline for the ultimate Merging.
So much like you have to stand up and use your leg muscles upright, before you can take a step and walk, I feel the natural tendency towards divine love, a stern logical compassion, feels to me like a first step towards the ultimate Dissolution above the Abyss.
Hopefully this very limited personal experience has given you a glimpse of what reaching the dissolution of the ego may look like psychologically. I am not close, but I am closer than I was.
