“They” say that life is a circle. I took that to mean that life went in a circle like a race car on a track all life ended where it began a form of cosmic redundancy. I think I may have misinterpreted that thought after examining the growth rings of some recently cut down trees. The growth rings of the trees radiated out from the epicenter of the trunk and ended when the life the tree did.
You can see the same thing on a calm day when you toss a stone into water and watch as concentric rings of energy spread out until the momentum dissipates and events return to stillness.
Like the tree, the ripples in the water, the universe and life we start at one point and radiate out from the beginning until our energy ends and we return to stillness.
