The prakaraṇa text called "Pañcīkaraṇa", attributed to Śaṅkara, is investigated here. Through a comparative analysis with Śaṅkara's commentaries on the "Gītā" and some of the principal "Upaniṣads", it is shown that this text is most probably genuine. The background of Yoga in pre-Śaṅkaran Vedānta and in Śaṅkara's thought is completely reevaluated, and the need to develop new criteria to determine the validity of the attribution of these texts to Śaṅkara is highlighted.
