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

tulyam tu darśanam
tulyam—equal; tu—but; darśanam—scriptural; revelation.
But the same thing is seen in the scriptures.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
The word "tu" (but) here is used to begin the refutation of the idea that
transcendental knowledge is an inferior by-product of the performance of Vedic
rituals. The sūtra explains that there is equal scriptural evidence to show that
transcendental knowledge is not subordinate to Vedic rituals. In the Bṛhad-
āraṇyaka Upaniṣad it is said:
etad dha sma vai vidvāṁsa āhur ṛṣayaḥ kārayeyāḥ kim arthā vayam adhyeṣyāmahe
kim arthā vayaṁ yakṣāmahe etad dha sma vai pūrve vidvāṁso 'gni-hotraṁ
juhavāṁ cakrire etaṁ vai tam ātmānaṁ viditvā brāhmaṇāḥ putra-pauṣāyāś ca
vitteṣaṇāyāś ca lokaiṣaṇāyāś ca vyutthāya bhikṣā-caryaṁ caranti.
"The wise sages asked, `Why do we study the Vedas? Why do we perform
yajñas?' Then the sages stopped performing agnihotra-yajñas. Learning the truth
about the Supreme Personality of Godhead, the brāhmaṇas renounced all desire to
attain sons, grandsons, wealth, or anything else in this world. They became
sannyāsī beggars traveling here and there."
In many places the scriptures describe many great souls learned with
transcendental knowledge who renounced all Vedic rituals. These statements of
scripture do not contradict the descriptions of great souls performing Vedic
rituals, for many great souls performed Vedic rituals, either to purify themselves or
to set a good example for the world to follow.
In the next sūtra Vyāsa refutes the argument given in sūtra 4.
Sūtra 10
asārvatrikī
asārvatrikī—not universal.
