Yes, that is the training program that the next level up runs, Nondual Universal Higher Mind, with its sole agenda to wake up all the dreamers. Every student gets a different program, where parts of duality "flip off". One sense can stop, all senses can stop, space can end, time can stop, effort can stop, suffering can stop, all death and disease can be reversed, and on and on and on. I have experienced all of these over three decades.
Yes, detachment like the Buddha said. Or equivelently being the observer...like Jesus's "Be passer by" in gospel of thomas. Identity uplevel shift, to I am Whole, Complete, Happy space of nondual Universal Higher Mind.
At some point, all of duality "flips off", and one Merges into Being the Universal Higher Mind. Buddha said "I Am Awake". Jesus called it the "City of Light high on a hill that cannot be hidden", beingness noncontingency.
I experienced this in 2018, age 60, 20 year after experiencing Source Reality in 1998. Not permanent, but always in the background.
