Mandukya Upanishad

The Mandukya Upanishad is a key text in Hindu philosophy that explores the nature of reality and the self. It discusses the concept of "Aum," representing the three states of consciousness: waking (Jagrat), dreaming (Swapna), and deep sleep (Sushupti), along with a fourth state called Turiya, which signifies pure awareness and enlightenment. The text emphasizes the unity of the individual soul (Atman) with the ultimate reality (Brahman), illustrating that understanding this relationship leads to spiritual liberation. It is revered for its deep insights into the nature of existence and consciousness.
