Rigveda Upanishads
Upanishads of the Rigveda tradition — the Aitareya and Kaushitaki Upanishads — exploring the cosmic creation, the nature of Prana, and Brahman as pure Consciousness (Prajnanam Brahma).
Upanishad Group·Rigveda / Shruti·Language: Sanskrit·Composed: 700–500 BCE
- The Rigveda tradition has two principal Upanishads — the Aitareya and the Kaushitaki.
- Both are embedded in the Aitareya Aranyaka and Kaushitaki Brahmana Aranyaka respectively — the "forest texts" appended to the Rigveda.
- The Aitareya is one of the ten principal Upanishads (Dasopanishad); the Kaushitaki is secondary but important.
- Their central contribution is the insight into consciousness as the ground of creation — culminating in the Mahavakya: Prajnanam Brahma — Consciousness is Brahman.
- They discuss cosmic creation (Hiranyagarbha), the nature of Prana, the two paths after death (Devayana and Pitriyana), and the identity of the self with the cosmic Self.
