Aitareya Upaniṣad
The Aitareya Upaniṣad is associated with the Ṛgveda, comprising the fourth, fifth, and sixth chapters of the second book of the Aitareya Āraṇyaka, and is one of the principal Upaniṣads. It is traditionally attributed to the sage Mahidāsa Aitareya and explores the nature of consciousness and the creation of the world.
Overview
The text is divided into three chapters (adhyāyas), each dealing with different aspects of creation, consciousness, and the Self. The first chapter addresses the creation of the universe, the second the creation of the individual, and the third the nature of consciousness.
Content
The text opens with a cosmogonic account describing how the universe emerged from consciousness (ātman). It then describes how the senses were created and directed outward, leading to the experience of the external world. The text culminates with the teaching that the Self is the creator of all and that it alone is Brahman, expressed in the mahāvākya “prajñānam brahma” (consciousness is Brahman).
Significance
The Aitareya Upaniṣad is significant for its early and systematic treatment of the relationship between consciousness and creation. It presents a unique perspective where the world is created through the expansion of consciousness rather than through material causation. This philosophy has influenced later idealistic schools of Indian thought.
Verification notes
