Vedic and Upanishadic thought

The Vedas present Rta, the cosmic order that keeps seasons, sacrifices and moral life in rhythm, while the Upanishads turn inward to Atman and Brahman. For example, the Mandukya Upanishad maps waking, dream, deep sleep and turiya onto the syllable Om. This chapter connects yajna, creation theories and the four states of consciousness into one exam-ready framework.
