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

sākṣāt—directly; api—also; avirodham—without contradiction; jaiminiḥ—Jaimini.
Jaimini is of the opinion that the word "agni" may be interpreted to directly
mean "The Supreme Personality of Godhead," and there is no inconsistency in
this.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
Just as the word vaiśvānara, interpreted to mean either "the leader (nara) of the
world (viśva) or "the proprietor of all human beings (nara) in the universe
(viśva)," is name of the Supreme Personality of Godhead, the original cause of all
causes, in the same way the word agni, interpreted to mean "the leader of all," is
also a name of Lord Viṣṇu. Jaimini Muni considers that there is no contradiction
in these interpretations because they are based on the specific meanings of each
word's component parts.
The objector may say: How can the limitless Supreme Personality of Godhead
become the size of the distance between the thumb and forefinger, (as vaiśvānara
is said to be in this passage of the Upaniṣad)?
To answer this question he says:
Sūtra 30
abhivyakter ity āśmarathyaḥ
abhivyakteḥ—because of manifestation; iti—thus; āśmarathyaḥ—Āśmarathya.
Āśmarathya is of the opinion that the Supreme Personality of Godhead appears
in this way (a size the distance between the thumb and forefinger) because He
manifests Himself (in the heart of His devotee).
Purport by Śrīla Baladeva Vidyābhūṣaṇa
Lord Viṣṇu appears in this way in the hearts of His devotees, who have the eyes
to see Him. This is the opinion of Āśmarathya.
