<p>The <i>Sanatsujātīya</i>- and <i>Viṣṇusahasranāma</i>-<i>Bhāṣya</i> are traditionally attributed to Śaṅkara. However, a recent computational stylometric study conducted by Ivan Andrijanić and Jacek Bąkowski using the General Imposters authorship verification method challenges the traditional authorship attribution to Śaṅkara. In this paper, the authorship of these two works are re-examined from a more traditional perspective. The analysis of doctrinal and terminological peculiarities reveals the presence of later Vedāntic concepts and citation practices unusual for Śaṅkara. Moreover, in both commentaries, there is a quotation of two verses from the <i>Bhṛgu</i>-<i>Saṃhitā</i>, which could be dated to the twelfth century, serving as a key argument against Śaṅkara’s authorship. On the other hand, the General Imposters algorithm detected significant similarities between both texts, suggesting that they share a common authorship. Notably, the commentary on the <i>Śvetāśvataropaniṣad</i>, a text that includes the same two quotations from the <i>Bhṛgu</i>-<i>Saṃhitā</i>, is also attributed, through the General Imposters method, to the same author responsible for the commentaries on the <i>Sanatsujātīya</i> and <i>Viṣṇusahasranāma</i>. Hence, the second, and most crucial, part of this paper will analyse these three texts, unveiling striking correspondences among them and proposing the possibility that a single author crafted all three. Furthermore, thanks to the critical apparatus of the <i>Mahābhārata</i>, the <i>Sanatsujātīya</i>-<i>Bhāṣya</i> can even be geographically located in the southwest of India, which suggests a place of origin for all three <i>Bhāṣya</i>s, assuming they do indeed share authorship.</p>
