संज्ञातश्चेत्, तदुक्तम्, अस्ति तु तदपि ॥ ८ ॥
saṃjñātaścet, taduktam, asti tu tadapi || 8 ||
saṃjñātaḥ—On account of the name (being same); cet— if; tat—it; uktam—has already been answered; asti—exists; tu—but; tat—that; api—even.
8. If on account of the name (of both Vidyas being the same, it be said that they are one), it has already been answered. But even that (identity of name in Vidyas admitted to be different) exists.
Identity of name is no reason for claiming unity of Vidyas, since the subject-matter differs. This has already been established in the last Sutra. Moreover, it is borne out by the scriptures. For example, the different sacrifices like Agnihotra, Darsapurnamasa, etc., which all occur in Kathaka, are known as Kathakas; or even the Udgitha Upasanas of Chh. 1. 6 and Chh. 1. 9. 2 are different Vidyas.
