गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

Thus knowledge of the Supreme Personality of Godhead is the final conclusion taught by all the Vedas. Why is that? The sūtra explains: "because the Vedic injunctions and all other sources of real knowledge are not genuinely different." The "other sources of real knowledge" here refers to logic. In the Bṛhad-āraṇyaka Upaniṣad (1.4.7) it is said: ātmety evopāsīta "One should worship the Supreme." These words, as well as the promptings of logic, confirm the truth that these statements and many others like them in passages of all the Vedas, all describe the same Supreme Lord. The same Supreme Lord is described in the same way in the Kaṇva, Mādhyandina, and other recensions of the Vedas. Here someone may object: In one part of the Vedas (Bṛhad-āraṇyaka Upaniṣad 3.9.28) it is said: vijñānam ānandam brahma "The Supreme is knowledge and bliss." However, in another part of the Vedas (Muṇḍaka Upaniṣad 1.1.9) it is said: yaḥ sarva-jñaḥ sarva-vit "The Supreme knows everything." Because in this way each branch of the Vedas speaks differently of the Supreme, they do not all describe the same object as the Supreme. If this is said, the author of the sūtras gives the following reply. Sūtra 2 bhedād iti cen naikasyām api bhedāt—because of difference; iti—thus; cet—if; na—not; ekasyām—in one; api—also.
