Yes, although The Egg ultimately presumes separation of consciousness at some "higher level" given that there is a dialogue between such consciousnesses. My greater sense of loneliness comes from a sense that the very premise of a separation of consciousness exists as a deliberate goal of our universe, which was made by a "God" who is actually all of us, as a means to keep myself/ourself company and to introduce love. Sort of like we are all branches of the same tree. But people talk about having epiphanies about this as if it is a good thing that we are all the same, leading to a connectedness. But it also leads to loneliness.
Sorry for the dump.
