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

Saṁśaya (doubt): Must one always worship Lord Hari as Kṛṣṇa or is it possible
to worship Him in another form also?
Pūrvapakṣa (the opponent speaks): Because this passage ends the Upaniṣad the

obstruction; phalam—fruit.

yatrāsau saṁsthitaḥ kṛṣṇas
tribhiḥ śaktyā samāhitaḥ
rāmāniruddha-pradyumnai

"Lord Kṛṣṇa, accompanied by His three potencies and by Balarāma, Aniruddha,
Pradyumna, and Rukmiṇī, stays in delightful Mathurā Purī. These four names are
