Watch an anthill from above.
Zoom out far enough and the boundary between self and world starts to look painted on. This is the heart of monism and the oneness the Overview Effect keeps pointing at: what feels like a crowd of separate individuals is one organism moving with one purpose, seen from too close. The ant cannot picture the colony; we cannot picture the whole we already belong to. Every border we defend is a line drawn on a single body. We invite you to look down at your own patch of sand and ask how much of it was ever really separate.
