Confessions, Jacob Boehme, Chap5: " the Being of God is like a wheel, wherein many wheels are made one in another, upwards, downwards, crossways, and yet continually turn all of them together. At which indeed, when a man beholds the wheel, he highly marvels, and cannot at once in its turning learn to conceive and apprehend it. But the more he beholds the wheel the more he learns its form; and the more he learns the greatest longing he has towards the wheel, for he continually sees something that is more and more wonderful, so that a man can neither behold nor learn it enough.
onzeplumes, One of my many mottos (After all, having just one is never enough) is, "The day I stop learning will be the day I die."
I think I can comprehend the statement above, but the image threw me for a loop for a minute (Pun intended). At first glance, I didn't see a wheel or circles showing the direction of spin of the wheels. Rather I saw a sphere. And while both are round, the concept changes if either object is used.
Wheels are trapped by their shape to go in one direction only and can only change course through a outside influence which alters their angle or tilt. So a wheel within a wheel can only go in one direction. Either forwards or backwards. Linear movement.
A sphere within a sphere has the opportunity of being able to travel 360 degrees. It is capable of spherical and linear movement.
