A geometric torsion (GT) underlying a $2$-form in a $(4$$+$$1)$-dimensional$U(1)$ gauge theory is revisited with a renewed perspective for anon-perturbation (NP) gravity in $d$$=$$4$. In the context we provide evidencesto a holographic correspondence between a bulk GT and a boundary NP gravity.Interestingly the Killing symmetries in General Relativity (GR) are shown toprovide a subtle clue to the quantum gravity. The NP gravity is shown toincorporate a $(B_{2}$$ \wedge $$F_{2})$ coupling, sourced by a non-Newtonianpotential, to an exact geometry in GR. Remarkably the NP correction isidentified as a mass dipole and is shown to be sourced by a propagating GT. Adetailed analysis is performed in a bulk GT to show a modification to theprecession of perihelion in a boundary NP gravity. The perspective of anelectromagnetic (EM) wave in the bulk is investigated to reveal a spin $2$(mass-less) quantum sourced by an apparent 2-form. A Goldstone scalar isabsorbed by the apparent 2-form to describe a massive $2$-form in the coulombgauge. Alternately a Goldstone scalar together with a local degree of GT and2-form is argued to govern a composite (mass-less) spin $2$ particle in Lorentzgauge. Both the scenarios, further ensure a graviton in a boundary NP gravity.A qualitative analysis reveals a (non-interacting) graviton underlying aplausible gravitational wave/particle duality in NP gravity.
