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

This meaning should be accepted because the pradhāna (unmanifested material
nature) is ultimately dependent on Him (the Supreme Brahman).
Purport by Śrīla Baladeva Vidyābhūṣaṇa
The meaning here is that because pradhāna is ultimately dependent on the
Supreme Brahman, which is the original cause of all causes, the creative actions of
pradhāna are not the original cause, but are themselves caused by the Supreme
Brahman. Because pradhāna is naturally inactive, it only acts when inspired by the
glance of Brahman. This is described in the following statements of Vedic
literature.
māyāṁ tu prakṛtiṁ vidyān
māyinaṁ tu maheśvaram
"The Supreme Personality of Godhead is a magician, and the material world is
His magical show."
Śvetāśvatara Upaniṣad (4.10)
asmān māyī sṛjate viśvam etat
"The master of Māyā creates this world."
Śvetāśvatara Upaniṣad (4.9).
ya eka varṇo bahudhā śakti-yogād
varṇān anekān nihitārtho dadhāti
"He who has no rival creates the varieties of this world, using His own
potencies according to His own wish."
Śvetāśvatara Upaniṣad (4.1).
sa eva bhūyo nija-vīrya-coditṁ
sva-jīva-māyāṁ prakṛtiṁ sisṛkṣatīm
