Yajurveda Upanishads
Upanishads of the Yajurveda tradition — Isha, Brihadaranyaka, Taittiriya, Katha, Shvetashvatara, and Maitri. The largest and most diverse group, spanning strict non-dualism, devotional theism, Yoga philosophy, and the doctrine of five sheaths.
Upanishad Group·Yajurveda / Shruti·Language: Sanskrit·Composed: 800–300 BCE
- The Yajurveda has more principal Upanishads than any other Veda — including the Isha, Brihadaranyaka (Shukla YV), and Taittiriya, Katha, Shvetashvatara, and Maitri (Krishna YV).
- Shukla (White) Yajurveda: Isha Upanishad (18 verses — the most concise) and Brihadaranyaka Upanishad (the largest of all Upanishads).
- Krishna (Black) Yajurveda: Taittiriya (Pancha Kosha), Katha (Nachiketa and Yama), Shvetashvatara (Brahman = Rudra/Shiva), and Maitri (Yoga and Samkhya).
- Three of the four Mahavakyas come from this group — Aham Brahmasmi (Brihadaranyaka), as well as the doctrines of five sheaths, four states of consciousness, and the two paths after death.
- The range is extraordinary: from pure non-dualism (Isha, Brihadaranyaka) to devotional theism (Shvetashvatara), from the dialogue with death (Katha) to yogic cosmology (Maitri).
