This article examines the claim that Truth (Satya) is the most sacred name of God — an ontological identification rather than a moral description — as encoded in the Vishnu Sahasranama (Satyah, Name 85), the Taittiriya Upanishad (Satyam Jnanam Anantam Brahma, Brahmananda Valli 2.1.1), and Shankaracharya's Advaita framework (Sat as the first face of Sat-Chit-Ananda). The article situates this claim against the Western correspondence theory of truth (Aristotle's De Interpretatione; Tarski's 1935 semantic formalisation), establishing where the two traditions converge and where the Vedantic claim is the more radical, ontological one. The Vedic concept of Rta (cosmic order) is examined as the structural and etymological predecessor of Satya. The article then constructs the Satya Equation: the correspondence between the Upanishadic definition of Satyam as that which undergoes no modification and the physicist's concept of invariance — demonstrated through Noether's theorem, the constancy of the speed of light in special relativity, and the extreme fine-tuning of fundamental constants (the fine-structure constant, the electron-proton mass ratio, and the strong nuclear force) documented by physicists including Martin Rees, Paul Davies, and Stephen Hawking. Gandhi's 1931 declaration in Young India — 'Truth is God' — is examined as the modern, ethically activated form of the Sahasranama's ontological claim. The conclusion identifies the practical and philosophical implications of treating Truth as the ground of both spiritual and scientific inquiry.
