| The [[Mandukya Upanishad]] describes four states of consciousness, namely waking consciousness, dream, and deep sleep, and [[turiya]], the base-consciousness. Waking consciousness, dream, and deep sleep are equated with the three bodies, while turiya is a fourth state, which is equated with atman and purusha. | | The [[Mandukya Upanishad]] describes four states of consciousness, namely waking consciousness, dream, and deep sleep, and [[turiya]], the base-consciousness.
