The [[Kauśītāki]] and [[Maitrāyaṇi]] Upanishads are sometimes added.  All these date from before the [[Common Era]]. From [[linguistics|linguistic]] evidence, the oldest among them are the Bṛhadāraṇyaka and Chāndogya Upanishads. The Jaiminīya Upaniṣadbrāhmaṇa, belonging to the late Vedic Sanskrit period, may also be included. Of nearly the same age are the Aitareya, Kauṣītaki and Taittirīya Upaniṣads, while the remnant date from the time of transition from Vedic to Classical Sanskrit.
