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

sarve vedā yat-padam āmananti
"All the Vedas describe the Supreme Personality of Godhead."
This means that the Supreme Lord is known by all the Vedas, or, in other
words, the Vedas reveal the truth of Lord Hari. The word "ca" (and) in this sūtra
hints, "as far as one has the power". They who have the power may worship the
Supreme Lord by performing the pious rituals described in all the branches of the
Vedas. They who do not have the power must worship the Supreme Lord by
performing the pious rituals described in their own community's branch of the
Vedas. The conclusion is that the Supreme Lord is the final object of knowledge
sought by all the branches of the Vedas. This truth was also described in the very
beginning of Vedānta-sūtra (1.1.4):
tat tu samanvayāt
"But that (Lord Viṣṇu is the sole topic of discussion in the Vedas) is confirmed
by all scriptures."
This truth is thus repeated here in the discussion of the properness of studying
the different qualities of the Supreme Lord. Because this repetition strengthens the
argument here, there is no fault in it.

Gopāla-tāpanī Upaniṣad (1.8), the Supreme Lord is described as a cowherd boy
dark like a tamāla tree, dressed in yellow garments, decorated with a Kaustubha
jewel, wearing a peacock-feather, playing graceful melodies on a flute, and
surrounded by gopas, gopīs, and surabhi cows. There He is the Deity of Gokula. In
the Rāma-tāpanī Upaniṣad, however, He is described as the Lord whose left side is
decorated by Jānakī-devī, holding a bow, the killer of Rāvaṇa and a host of
demons, and the king of Ayodhyā. In the Rāma-tāpanī Upaniṣad it is said:
