Go beyond science, into the region of metaphysics. Real religion is beyond argument. It can only be lived both inwardly and outwardly.

The saying contrasts empirical inquiry (“science”) with metaphysical and spiritual realization. Sivananda’s point is not anti-scientific so much as hierarchical: reasoned argument can clarify concepts, but it cannot by itself deliver the lived transformation that religious life aims at. “Beyond argument” suggests that ultimate religious truth is verified through practice—ethical discipline, meditation, devotion, and self-inquiry—rather than through debate. The inward/outward pairing emphasizes integrity: genuine spirituality must be an inner state (purity of mind, compassion, detachment) expressed in conduct (service, restraint, truthfulness). The quote thus frames religion as experiential and embodied, not merely doctrinal.
