The unity and oneness that is present in many philosophies is visible for me in 3D as individuality, cells, eggs, planets, nonetheless each embedded in a reality of multiples of those, kind of like a fractal, self-similar. I liked what Nassim Haramein said about that (paraphrasing, don't remember exactly): "Everybody talks about the fractal universe, but did you notice that all people come out of other people?" Also the embryo/fetus/baby in Odyssey 2001 struck me as to keep in mind.If every egg is a cell, is every cell an inter-density 'egg' ready for trans-density fertilization - to be seeded by 4D? The Wave is like cosmic semen... And Earth awaiting density-fertilization in keeping with cosmic ovulation cycles.
The splitting of realities mentioned by the Cs (and clearly observable by now) might also fall into that area. The forced unity of new age philosophies and liberals might be to prevent the explosion of possibilities and realities taken by different parts of humanity, and the unity might be just a very short intersection point of many past human and earth realities.
