All in nature is circular, from the rotation of the electrons around the neutrons and protons, from the actual spheres of the atoms, of all the globes in heaven – everything must teach us something, what does the circle shape teach us?

As the Alter Rebbe teaches, what is unique about a circle is it has no beginning and no end.

In other words, life, the globe upon which our life and time take place (time itself is based on a circular motions as is well known – a clock being a good example, as well) has no beginning and has no end – it begins only in existence, but never ends; like the miracle of time, continuous rotation, so to, our lives have no end, they only have rebirth, continually, perpetually, infinitely, eternally!!!
