When doing my alchemy theories, I questioned what 7 would represent in terms of Rain World, as there aren't really 7 of anything- aside from Red Suns. There's no hard proof or anything. And I even wondered why there wheresn't 7 urges
But I remembered, like in the image I posted yesterday, the urges are moreso like elements. The ability to destroy, reproduce, connect, and process, all coming together to be aspects of the 5th karma, Self Preservation
And like the elements, everything in the ripplespace abides by these rules. The strands, on an outside view, almost act like animals trying to keep themselves alive and going through a material body. I suppose its less that the strand is you, and moreso you are the strand(s)
