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

(The speculations of the logicians are unable to teach us about Supreme
Personality of Godhead) because He may only be known by the revelation of the
Vedic scriptures.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
In this sūtra the word "not" should be understood, even though it is not
expressed. They who aspire after liberation are not able to understand the
Personality of Godhead simply by logic and speculation. Why? Because He is
known only by the revelation of the Vedic scriptures. Among the Vedic scriptures,
the Upaniṣads especially describe the Supreme Person. For this reason it is said
aupaniṣadaṁ puruṣam (the Supreme Person is undertood through the revelation of
the Upaniṣads). The process of logic and speculation as described by the word
mantavya (to be understood by logic) as described in Bṛhad-āraṇyaka Upaniṣad
(4.5) should be employed to understand the revelation of the scriptures and not
independently. This is confirmed by the following statement of śruti-śāstra:
pūrvāpara-virodhena
ko 'rtho 'trābhimato bhavet
ity ādyam ūhanaṁ tarkaḥ
śuṣka-tarkaṁ vivarjayet
"Logic is properly employed to resove apparent contradictions in the texts of
the Vedas. Dry logic, without reference to scriptural revelation, should be
abandoned."
For this reason the dry logic of Gautama and others should be rejected. This is
also confired in sūtra 2.1.11. After understanding the Supreme Person by study of
the Upaniṣads, one should become rapt in meditation on Him. This will be
explained later insūtra 2.1.27.
The Supreme Lord, Hari, is identical with His own transcendental form. He and
His form are not two separate identities. He is the witness of all living entities, He
is the resting place of a host of transcendental qualitities, He is the creator of the
material universes, and He remains unchanged eternally. By hearing about His
transcendental glories, one may worship Him perfectly.
At this point someone may raise the following objection:
The Vedānta philosophy does not give either positive orders or negative
prohibitions, but simply descriptions, as the sentence "On the earth there are
seven continents." Men need instruction in how to act. Therefore, what is needed
is a series of orders to guide men. Men need orders, such as the ordinary orders.
"A man desiring wealth should approach the king," or "One suffering from
indigestion should restrict his intake of water," or the orders of the Vedas: svarga-
kāmo yajeta (One desiring to enter the celestial material planets should worship
