what is the difference between upanishads and vedas
All Upanishads are associated with one of the four Vedas.
Upanishads
All Upanishads are associated with one of the four Vedas—Rigveda, Samaveda, Yajurveda (there are two primary versions or "Samhitas" of the Yajurveda: Shukla Yajurveda, Krishna Yajurveda), and Atharvaveda. During the modern era, the ancient Upanishads that were embedded texts in the Vedas, were detached from the Brahmana and Aranyaka layers of Vedic text, compiled into separate texts and these were then gathered into anthologies of the Upanishads. These lists associated each Upanishad with one of the four Vedas, many such lists exist, and these lists are inconsistent across India in terms of which Upanishads are included and how the newer Upanishads are assigned to the ancient Vedas.
