From the Brahmanical perspective, the Yoga Upaniṣads are sacred, but these are not very interesting sources of yoga history. For the tantric practitioner, some of the tantras represent the most sacred source of yogic teaching and practice. Several haṭhayogic texts also claim divine origin, and many other yoga texts are attributed to various legendary or semi-legendary Hindu sages, including Patañjali.
