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

As for the various fruitive results, such as the attainment of rain, a son, or residence in the celestial material planets, that are offered to the follwers of the karma-kāṇḍa rituals in the Vedas, these beneifts are offered to attract the minds of ordinary men. When ordinary men see that these material benefits are actually attained by performing Vedic rituals, they become attracted to study the Vedas. By studying the Vedas they become able to discriminate between what is temporary and what is eternal. In this way they gradually become averse to the temporary things of this world and they come to hanker after Brahman. In this way it may be understood that all the parts of the Vedas describe the Supreme Personality of Godhead. Vedic rituals bring material benefits as a result only when the performer of the ritual is filled with material desire. If the performer is materially desireless, then he does not gain a material result, but rather the result he obtains is purification of the heart and the manifestation of spiritual knowledge. Therefore, the meaning of the previously quoted text from Bṛhad-āraṇyaka Upaniṣad (4.4.22) is that the demigods are considered to be the various limbs of the Supreme Personality of Godhead, and by worshiping them, one actually worships the Supreme Lord, and the result of such worship is that one gradually become pure in heart and awake with spiritual knowledge. Adhikaraṇa 5 Brahman Is Knowable

1. Viṣaya (statement): Now, by the use of logic and scriptural quotation, we shall refute the misconception that Brahman cannot be described. One may argue, however, that many scriptural passages support the theory that Brahman cannot be described by words. For example: yato vāco nivartate aprāpya manasā saha "The mind cannot understand the Supreme Personality of Godhead and words cannot describe Him." —Taittrīya Upaniṣad 2.4.1 yad vacanābhyuditaṁ yena vāg abhyudyate tad eva brahma tad viddhi nedaṁ yad idam upāsate "No one has the power to describe Brahman with words, even though everyone's speech occurs by the power granted by Brahman. Know that this Brahman is not material. Worship this Brahman."
