The Vedic knowledge is infallible because it comes down directly from the Supreme Lord unto the heart of Brahmā, and since he is the most perfect living being, Brahmājī is always correct to the letter. And this is because Lord Brahmā is a great devotee of the Lord who has earnestly accepted the lotus feet of the Lord as the supreme truth. In theBrahma-saṁhitā, which is compiled by Brahmājī, he repeats the aphorism govindam ādi-puruṣaṁ tam ahaṁ bhajāmi: ** "I am a worshiper of the original Personality of Godhead, Govinda, the primeval Lord." So whatever he says, whatever he thinks, and whatever he does normally in his mood are to be accepted as truth because of his direct and very intimate connection with Govinda, the primeval Lord.
(Srimad Bhagavatam-----2:6:34-----purport).

No one can know the Personality of Godhead in full, but at least to a certain extent one can know the Absolute Truth, the Personality of Godhead, by self-surrender and a devotional attitude, and by nothing else. In the Brahma-saṁhitā also, it is said, vedeṣu durlabham, or simply by study of Vedānta one can hardly find out the existence of the Personality of Godhead, but the Lord is adurlabham ātma-bhaktau, very easily available to His devotee. Śrīla Vyāsadeva, therefore, was not satisfied simply with compiling the Vedānta-sūtras, but over and above this, by the advice of his spiritual master, Nārada, he compiled the Śrīmad-Bhāgavatam in order to understand the real import of Vedānta. Śrīmad-Bhāgavatam therefore, is the absolute medium by which to understand the Absolute Truth.
(Srimad Bhagavatam-----2:6:35-----purport).

In the Brahma-saṁhitā it is stated that although He is the oldest personality among all living entities, He always looks like a new, youthful boy. That is the characteristic of a spiritual body. The material body is symptomized by birth, death, old age and diseases, but the spiritual body is conspicuous by the absence of those symptoms. Living entities who reside in the Vaikuṇṭhalokas in eternal life and bliss have the same type of spiritual body, without being affected by any signs of old age.
(Srimad Bhagavatam-----2:7:26-----purport).

So Brahmājī was thus initiated by Lord Kṛṣṇa, and this fact is corroborated by Brahmājī himself in his book the Brahma-saṁhitā. In the Brahma-saṁhitā Lord Brahmā has sung in every verse govindam ādi-puruṣaṁ tam ahaṁ bhajāmi **. Thus Brahmā was initiated by the Kṛṣṇa mantra, by Lord Kṛṣṇa Himself, and thus he became a Vaiṣṇava, or a devotee of the Lord, before he was able to construct the huge universe. It is stated in the Brahma-saṁhitā that Lord Brahmā was initiated into the eighteen-letter Kṛṣṇa mantra, which is generally accepted by all the devotees of Lord Kṛṣṇa. We follow the same principle because we belong to the Brahmā sampradāya, directly in the disciplic chain from Brahmā to Nārada, from Nārada to Vyāsa, from Vyāsa to Madhva Muni, from Madhva Muni to Mādhavendra Purī, from Mādhavendra Purī to Īśvara Purī, from Īśvara Purī to Lord Caitanya and gradually to His Divine Grace Bhaktisiddhānta Sarasvatī, our divine master.
(Srimad Bhagavatam-----2:9:6-----purport).

In the Brahma-saṁhitā it is said that the Lord has a transcendental form and that He can utilize any one of His senses for any purpose. For example, He can eat with His eyes, and He can see with His leg. In the mundane conception of form, one cannot eat with one's eyes or see with his leg.
(Srimad Bhagavatam-----2:9:32-----purport).

This Supreme Personality of Godhead in the ultimate issue is confirmed by Brahmā in his Brahma-saṁhitā as īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1). So it is concluded in the Third Canto of the Śrīmad-Bhāgavatam. The complete subject matter is elaborately explained in the Tenth and Eleventh Cantos of the Śrīmad-Bhāgavatam. In the matter of the changes of the Manus or manvantaras, such as the Svāyambhuva-manvantara and Cākṣuṣa-manvantara, as they are discussed in the Third, Fourth, Fifth, Sixth and Seventh Cantos of Śrīmad-Bhāgavatam, Lord Kṛṣṇa is indicated.
(Srimad Bhagavatam-----2:10:7-----purport).

These are Brahmā's days only, and he has to live months and years up to one hundred, so we can just imagine how many creations there are in kalpas only. Then again there are vikalpas, which are generated by the breathing of Mahā-Viṣṇu, as stated in the Brahma-saṁhitā (yasyaika-niśvasita-kālam athāvalambya jīvanti loma-vilajā jagadaṇḍa-nāthāḥ (Bs. 5.48)). The Brahmās live only during the breathing period of Mahā-Viṣṇu. So the exhaling and inhaling of Viṣṇu are mahā-kalpas, and all these are due to the Supreme Personality of Godhead, for no one else is the master of all creations.
(Srimad Bhagavatam-----2:10:46-----purport).

The Lord is never detached from the association of parā śakti. This parā śakti and her manifestations are described in the Brahma-saṁhitā (5.37) as ānanda-cinmaya-rasa-pratibhāvitābhiḥ. The Lord is eternally joyful and cognizant in the taste derived from such transcendental bliss. Negation of the variegatedness of the inferior energy does not necessitate negation of the positive transcendental bliss of the spiritual world.
(Srimad Bhagavatam-----3:3:20-----purport).

The Lord's detachment from household life does not indicate detachment from His eternal associates, the transcendental cowherd damsels. But the Lord desired to end His so-called attachment to the three modes of material nature. He can never be detached from the service of His transcendental associates like Rukmiṇī and other goddesses of fortune, as described in the Brahma-saṁhitā (5.29): lakṣmī-sahasra-śata-sambhrama-sevyamānam.
(Srimad Bhagavatam-----3:3:22-----purport).

Persons who are themselves under the control of supernatural power cannot believe that Lord Kṛṣṇa is not under any control beyond Himself in the matter of sense enjoyment. They cannot understand that His senses are transcendental. In the Brahma-saṁhitā the Lord's senses are described as omnipotent; i.e., with any sense He can perform the activities of the other senses.
(Srimad Bhagavatam-----3:3:23-----purport).

According to Brahma-saṁhitā, the Lord has many forms. It is stated therein that the Lord has innumerable forms, and when He appears within the vision of the living entities, as Lord Kṛṣṇa actually appeared, all such forms amalgamate with Him. Besides all these infallible forms, He has His universal form, as manifested before Arjuna on the Battlefield of Kurukṣetra.
(Srimad Bhagavatam-----3:4:29-----purport).

The Brahma-saṁhitā says that it is very difficult to understand the Supreme Personality of Godhead from the Vedas, but He is easily understood from a pure devotee like Uddhava. Taking mercy on the great sages who lived at Badarikāśrama, the Lord authorized Uddhava to speak on His behalf. Unless one has such authorization, one cannot understand or preach the devotional service of the Lord.
(Srimad Bhagavatam-----3:4:32-----purport).

This fact is confirmed in Brahma-saṁhitā (5.37): goloka eva nivasaty akhilātma-bhūtaḥ. "The Lord, by His inconceivable potency, resides in His eternal abode, Goloka, yet at the same time, as the Supersoul, He is present everywhere—in both the spiritual and material skies—by His multivarieties of manifestation."
(Srimad Bhagavatam-----3:4:33-----purport).

The omnipotent Lord can impregnate just by His eyes, and therefore He is called all-potent. Each and every part of His transcendental body can perform each and every function of the other parts. This is confirmed in the Brahma-saṁhitā (5.32): aṅgāni yasya sakalendriya-vṛttimanti. In Bhagavad-gītā (14.3) also, the same principle is confirmed: mama yonir mahad-brahma tasmin garbhaṁ dadhāmy aham. When the cosmic creation is manifested, the living entities are directly supplied from the Lord; they are never products of material nature.
(Srimad Bhagavatam-----3:5:26-----purport).

In the Brahma-saṁhitā it is stated that the sun is the eye of the Supreme and it rotates in its particular orbit of time. Similarly, beginning from the sun down to the atom, all bodies are under the influence of the kāla-cakra, or the orbit of eternal time, and each of them has a scheduled orbital time of one saṁvatsara.
(Srimad Bhagavatam-----3:11:13-----purport).

There is complete agreement between Śrīmad-Bhāgavatam and the Brahma-saṁhitā. Eternal time is never lost along with the life of Brahmā. It continues, but it has no ability to control the Supreme Personality of Godhead because the Lord is the controller of time. In the spiritual world there is undoubtedly time, but it has no control over activities. Time is unlimited, and the spiritual world is also unlimited, since everything there exists on the absolute plane.
(Srimad Bhagavatam-----3:11:38-----purport).

It is stated in the Brahma-saṁhitā that His eyes are the sun and the moon; therefore His very glance over the sky was as illuminating as the sun or the moon. The Lord is described herein as mahīdhraḥ, which means either a "big mountain" or the "sustainer of the earth."
(Srimad Bhagavatam-----3:13:27-----purport).

In the Brahma-saṁhitā it is stated that the Supreme Lord, Govinda, is always served in His abode by many, many millions of goddesses of fortune. Lakṣmī-sahasra-śata-sambhrama-sevyamānam (Bs. 5.29). These millions and trillions of goddesses of fortune who reside in the Vaikuṇṭha planets are not exactly consorts of the Supreme Personality of Godhead, but are the wives of the devotees of the Lord and also engage in the service of the Supreme Personality of Godhead. It is stated here that in the Vaikuṇṭha planets the houses are made of marble. Similarly, in the Brahma-saṁhitā it is stated that the ground on the Vaikuṇṭha planets is made of touchstone.
(Srimad Bhagavatam-----3:15:21-----purport).

It is said in the Brahma-saṁhitā that devotees, being elevated in love of God, always see Śyāmasundara, the Supreme Personality of Godhead, within their hearts. But when they are mature, the same God is visible before them face to face.
(Srimad Bhagavatam-----3:15:38-----purport).

He is especially inclined to His devotee; He touches the core of the heart of the devotee simply by smiling and glancing over him. The Lord is always served in the Vaikuṇṭhaloka by many hundreds and thousands of goddesses of fortune, as stated by the Brahma-saṁhitā (lakṣmī-sahasra-śata-sambhrama-sevyamānam (Bs. 5.29)).
(Srimad Bhagavatam-----3:15:39-----purport).

Even if they are satisfied in their minds, still, transcendentally, their eyes are not satisfied. But as soon as such persons come to realize the Supreme Personality of Godhead, they are satisfied in all respects. In other words, they become devotees and want to see the form of the Lord continually. It is confirmed in the Brahma-saṁhitā that one who has developed transcendental love of Kṛṣṇa by smearing his eyes with the ointment of love sees constantly the eternal form of the Lord.
(Srimad Bhagavatam-----3:15:50-----purport).

The defenseless creatures, according to Brahma-saṁhitā, are the cows, brāhmaṇas, women, children and old men. Of these five, the brāhmaṇas and cows are especially mentioned in this verse because the Lord is always anxious about the benefit of the brāhmaṇas and the cows and is prayed to in this way.

(Srimad Bhagavatam-----3:16:10-----purport).
