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

Sūtra 4 na vilakṣaṇatvād asya tathātvaṁ ca śabdāt Because they have a fundamentally different nature, and because their own words are evidence for them, the Vedas are not an unreliable source of knowledge. Purport By Śrīla Baladeva Vidyābhūṣaṇa The Vedas are not an unreliable source of knowledge, as the sāṅkhya-smṛti and yoga- smṛti are. Why? The sūtra says vilakṣaṇāt (Because they have a fundamentally different nature). This means that because they were written by jīvas, the saṅkhya-smṛti and yoga- smṛti are subject to the four defects of being prone to mistakes, illusions, cheating, and defective perception. the Vedas, however, because they are eternal, are free from these defects. The śruti says vācā virūpa nityayā (O Virūpa, the Vedas are eternal) and the smṛti says: anādi-nidhanā nityā* vāg utsṛṣṭā svayambhuvā ādau vedamayī divyā yataḥ sarvāḥ pravṛttayaḥ "In the beginning of creation the Supreme Personality of Godhead spoke and from His words the eternal, beginningless, endless, transcendental Vedas were manifested. From the Vedas all other scriptures have come." The Manu-smṛti and the other smṛtis authoritative because they have emanated from the Vedas. In a previous sūtra (1.3.29) the eternity of the Vedas was proved by logic, and in this sūtra it is proved by the Vedas themsleves. That is the difference between these two sūtras. An opponent may object: "In the Puruṣa-sūkta (Ṛṅ Veda 10.90.9) are the words: tasmād yajñāt sarva-huta* ṛcaḥ sāmāni jajñire chandāṁsi jajñire tasmād yajus tasmād ajāyata 'From that sacrifice all fire-sacrifices, the ṛg Veda and the Sāma Veda were born. From it the Vedic hymns were born. From it the Yajur Veda was born.' This passage proves that the Vedas were born and, because they were born, must also perish in the end. For this reason the Vedas are not eternal." To this opponent I say: No. It is not so. The word "born" here means "manifested" (not born in the ordinary sense). For this reason the scriptures say:
