Recently I have heard, “If you travel deep into any subject, you will end up at Zero”
In physics, we talk about Conservative forces. Viz., in Electricity, Electric potential is a Conservative force… independent of path. If we start at point and travel in any path and end at point A, the Potential, or the work done is Zero.
In both the cases, we can find symmetry. We end with Zero if we travel in any Conservative field. Now what could be this Analogy of Conservative field in Nature? 

May be Enlightenment, self realization, Universal Consciousness.. all these are Conservative fields?.. How much ever we travel, we end up with initial, Zero?
