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

Sūtra 22
avasthiter iti kāśakṛtsnaḥ
avasthiter -because of residence; iti -thus; kāśakṛtsnaḥ-Kāśakṛtsna.
This passage refers to Paramātmā, for Paramātmā resides within the jīva. This is
the opinion of Kāśakṛtsna.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
In this statement the word avasthiteḥ (residing) which refers to the Paramātmā,
the Great Being who is different from the jīva, and who is described as vijñāna-
ghana (full of knowledge), teaches that the Paramātmā is different from the jīva
and resides within him. Kāśakṛtsna considers that because the Paramātmā and the
jīva are different the words mahad-bhūtam (Great being), anantam (limitless) and
vijñāna-ghana cannot refer to the jīva. A summary of the passage from Bṛhad-
āraṇyaka Upaniṣad under discussion follows.
Yenāhaṁ nāmṛtaḥ syāṁ kim ahaṁ tena kuryām
"Tell me what I must do to become free of death."
Bṛhad-āraṇyaka Upaniṣad 4.5.4)
Asked this question about the means to attain liberation, the sage answered:
ātmā vā are draṣṭavyaḥ śrotavyo mantavyo nididhyāsitavyo maitreyy ātmano vā are
darśanena śravaṇena matyā vijñānena idaṁ sarvaṁ viditam
"The Self should be seen, heard, worshiped, and always meditated on. O
Maitreyī, by seeing, hearing, worshiping, and understanding the Self, everything
becomes known."
In this way he explains that the worship of Paramātmā is the way to attain
liberation.
Then he says:
sa yathā dundubher hanyamānasya bāhyāñ chabdāñ chakruyād grahaṇāya
dundubhes tu grahaṇena dundubhy-āghātasya vā śabdo gṛhītaḥ
