Aitareya Upanishad

Summary

The Aitareya Upanishad belongs to the Rig Veda and forms part of the Aitareya Aranyaka. It is a short prose text divided into three chapters. It deals primarily with the creation of the universe by the Self (Atman) and the entry of the Self into the human body.

It is most famous for containing one of the four Mahavakyas (Great Sayings) of the Vedas: "Prajnanam Brahma" (Consciousness is Brahman). The Upanishad explores the nature of the Self as the source of all perception and intelligence, asserting that everything in the universe is guided by and established in Consciousness.

Key Teachings

• Creation by the Self: "In the beginning, all this was Atman alone." The Self thought, "Let me create worlds," and thus created the four worlds (Ambhas, Marichi, Mara, Ap).
• Cosmic Powers: From the waters, He drew forth the Person (Purusha) and brooded upon him, manifesting the cosmic powers (Agni, Vayu, Aditya, etc.) and their corresponding sense organs.
• Entry of the Self: The Supreme Self entered the human body through the aperture at the crown of the head (Vidriti) to experience the world.
• Three Births: The soul undergoes three births: first as the seed in the father (conception), second as the child born from the mother (physical birth), and third as the departure after death to a new realm or liberation.
• Prajnanam Brahma: The ultimate realization that Consciousness (Prajna) is the foundation of the universe. All gods, elements, and beings are established in Consciousness. Consciousness is Brahman.
