  In this essay, I wish to share a novel perspective which envisions
universalization as a guide from the classical world to relativistic and
quantum world. It is the incorporation of zero mass particle in mechanics which
leads to special relativity while its interaction with a universal field shared
by all particles leads to general relativity. We also give a very simple
classical argument to show that why the universal force has to be attractive.
We try to envisage what sort of directions does this principle of universality
point to for the world beyond general relativity?
