How can we be individuals and be as one at the same time?
Think of different colours? Isn’t there a distinct difference between yellow and green? Of course there is. Yet when seen on the spectrum, the delineation is not as evident. Only when seen from a distance can we distinguish a gradual separation.
But when seen from even further away, we see all colours blend into unity. The part we see may seem white, but the spectrum extends far beyond our perception. If we pulled back further still (and had eyes evolved to see longer and shorter frequencies), we would see that white itself, though distinct, is but a part of a spectrum.
Yellow may be distinct from green or even ultra violet, but seeing the whole picture reveals that we are indeed all one.
Besides, in the end, it’s all just photons at different frequencies.
