Do the oldest Hindu texts call Brahman the one highest power, and when?
Research question: What do the earliest Vedic and Upanishadic texts say about Brahman as a single supreme principle, and when does that framing first appear?
The Nasadiya Sukta, the 129th hymn of the Rigveda's 10th mandala, describes a primordial state in which a single 'That One' breathed windlessly, with nothing beyond it 12. The records place this hymn in the last book of the Veda 9. Later Upanishads describe the Highest Brahman as the one reality besides which there is nothing, one that cannot be reached as an object 4, and the Brihadaranyaka identifies the Self with Brahman, the Immortal, and the All 3. The facts do not give composition dates for the Nasadiya or the Upanishads, so they cannot establish when the single-principle framing first appeared. The newest fact is a 2026 paper stating that truth and oneness are the fundamental attributes of Brahman 10.
