Full Circle

In school Maths class, there were questions like, given two formula "a" and "b" prove a=b.
So we would start out operating on "a", and applying all the theorems we know, try to bring out "b" from twisting and transforming "a".
Sometimes the end result of those transformations lead back to "a"... Hence we end up proving, a=a. :)
It was worth the laugh to realise we spent all that time, effort and theorems, go full circle and come back to prove a=a

In search of God, i keep reading so many books, keep looking out to find Him...for some secret access code and it ultimately leads back to oneself.
Read any religious book, somewhere or other you'll find that statement, that God can be found only in oneself, and not outside...
Travel full circle, and back to oneself agn.

I don't exactly know whats the common point between the maths theorem and the search for God.
Somehow my mind links those two as similar.... perhaps its the point that start and end points were same in both context, so posted them here in same place....
