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

"The pāṇas move in seven realms."
Thus the secondary prāṇas move among the senses.
Saṁśaya (doubt): Do the secondary prāṇas move by their own power among
the senses, or does something else create the movement of the prāṇas? Are the
prāṇas moved by the demigods, the individual spirit soul, or the Supreme
Personality of Godhead?
Pūrvapakṣa (the opponent speaks): Endowed with the power of action, the
prāṇas move themselves. Or perhaps the demigods move them. In the Aitareya
Upaniṣad (2.4) it is said:
agnir vāg bhūtvā mukhaṁ prāviśad
"Becoming speech, Agnideva entered the mouth."
Or perhaps the individual spirit soul moves the prāṇas. This may be so because
the prāṇas are instruments the soul uses to attain enjoyment.
Siddhānta (conclusion): In the following words the author of the sūtras gives
His conclusion.
Sūtra 14
jyotir-ādy-adhiṣṭhānaṁ tu tad āmananāt
jyotiḥ—effulgence; ādy-adhiṣṭhānam—the supreme ruler; tu—indeed; tat—
that; āmananāt—because of the description.
Indeed, light is the controller, because that is the description.

here means "the Supreme Personality of Godhead". He is the mover (adhiṣṭhānam)
of the prāṇas. The affix lyuṭ in the word “adhiṣṭhānam" makes it mean "the
mover". Why is the Supreme Personality of Godhead the mover of the prāṇas? The
