And Brahmā, the original living being, has explained the subject of Śrī Kṛṣṇa substantially in his treatise named Brahma-saṁhitā.
(Srimad Bhagavatam-----1:1:1-----purport).

In the Brahma-saṁhitā also it is said that the Lord is always visible to the devotees whose eyes have been anointed with the tinge of devotional service.
(Srimad Bhagavatam-----1:3:4-----purport).

In the Brahma-saṁhitā also it is said indirectly that although there are many incarnations of the Lord, such as Rāma, Nṛsiṁha, Varāha, Matsya, Kūrma and many others, the Lord Himself sometimes incarnates in person.
(Srimad Bhagavatam-----1:3:26-----purport).

In the Brahma-saṁhitā it is said that beginning from the indra-gopa germ up to the great Indra, King of heaven, all living beings are subjected to the law of karma and are bound to suffer and enjoy the fruitive results of their own work.
(Srimad Bhagavatam-----1:3:28-----purport).

There is no parallel to His childhood pastimes as exhibited at Vrajabhūmi, which are the prototypes of His eternal affairs in the original Kṛṣṇaloka described as the cintāmaṇi-dhāma in the Brahma-saṁhitā (Bs. 5.29). Lord Śrī Kṛṣṇa descended Himself at Vrajabhūmi with all His transcendental entourage and paraphernalia.
(Srimad Bhagavatam-----1:8:21-----purport).

The Paramātmā feature of the Lord is an expansion of His plenary portions. He expands Himself as Paramātmā in everyone's heart by His inconceivable energy, and He also expands Himself as the glowing effulgence of brahmajyoti by expansion of His personal glow. It is stated in the Brahma-saṁhitā that the brahmajyoti is His personal glow. Therefore, there is no difference between Him and His personal glow, brahmajyoti, or His plenary portions as Paramātmā. Less intelligent persons who are not aware of this fact consider brahmajyoti and Paramātmā to be different from Śrī Kṛṣṇa.
(Srimad Bhagavatam-----1:9:42-----purport).

This Mahā-Viṣṇu is the plenary portion of the Lord Śrī Kṛṣṇa, who is mentioned in the Brahma-saṁhitā as follows:
"Let me offer my respectful obeisances unto the original Personality of Godhead, Govinda, whose plenary portion is the Mahā-Viṣṇu. All the Brahmās, the heads of the universes, live only for the period of His exhaling, after the universes are generated from the pores of His transcendental body." (Bs. 5.58)
(Srimad Bhagavatam-----1:10:21-----purport).

The Supreme Lord is Śrī Kṛṣṇa, as confirmed in Bhagavad-gītā, Brahma-saṁhitā and other authorized Vedic literatures. No one is equal to or greater than Him, and that is the verdict of all scriptures. The influence of time and space is exerted upon the dependent living entities, who are all parts and parcels of the Supreme Lord. The living entities are predominated Brahman, whereas the Supreme Lord is the predominating Absolute.
(Srimad Bhagavatam-----1:11:6-----purport).

There have been so many big empires in different parts of the world, there have been so many powerful kings all over the world, and there have been so many fortunate men, but all of them have been liquidated gradually. This is the law of material nature. But spiritually it is different. According to Brahma-saṁhitā, the Lord is served very respectfully by hundreds and thousands of goddesses of fortune. They are always in a lonely place also with the Lord.
(Srimad Bhagavatam-----1:11:33-----purport).

It is said in the Brahma-saṁhitā (Ch. 5) that the Supreme Lord Govinda, by His one plenary portion, enters into the halo of the universe and distributes himself as Paramātmā, or the Supersoul, not only within the heart of every living being, but also within every atom of the material elements. Thus the Lord is all-pervading by His inconceivable potency, and thus He entered the womb of Uttarā to save His beloved devotee Mahārāja Parīkṣit.
(Srimad Bhagavatam-----1:12:9-----purport).

Gautama and Kaṇāda find that atomic combination is the cause of everything, and impersonalists like Aṣṭāvakra discover that the spiritual effulgence of Brahman is the cause of all causes. But in the Bhagavad-gītā the Lord Himself declares that He is the source of impersonal Brahman, and therefore He, the Personality of Godhead, is the ultimate cause of all causes. It is also confirmed in the Brahma-saṁhitā that Lord Kṛṣṇa is the ultimate cause of all causes.
(Srimad Bhagavatam-----1:17:19-----purport).

The Vedas say that the Supreme Lord has nothing to do personally, as is always the case with superiors, but everything is done by His direction. As it is said, not a blade of grass moves without His sanction. In the Brahma-saṁhitā (5.48), it is said that all the universes and the heads of them (the Brahmās) exist only for the duration of His breathing period. The same is confirmed here. The air on which the universes and the planets within the universes exist is nothing but a bit of the breath of the unchallengeable virāṭ-puruṣa. So even by studying the rivers, trees, air and passing ages, one can conceive of the Personality of Godhead without being misled by the formless conception of the Lord. In the Bhagavad-gītā (12.5) it is stated that those who are much inclined to the formless conception of the Supreme Truth are more troubled than those who can intelligently conceive of the personal form.
(Srimad Bhagavatam-----2:1:33-----purport).

A pure devotee therefore never approaches the Lord directly, but tries to please the servant of the Lord's servants, and thus the Lord becomes pleased, and only then can the devotee relish the taste of the tulasī leaves stuck to His lotus feet. In the Brahma-saṁhitā it is said that the Lord is never to be found by becoming a great scholar of the Vedic literatures, but He is very easily approachable through His pure devotee. In Vṛndāvana all the pure devotees pray for the mercy of Śrīmatī Rādhārāṇī, the pleasure potency of Lord Kṛṣṇa.
(Srimad Bhagavatam-----2:3:23-----purport).

The mundaners are mostly worshipers of Durgā-devī, the external energy of Kṛṣṇa, but they do not know that Durgā-devī is but the shadow energy of the Lord. Behind her astonishing display of material workings is the direction of the Lord, as confirmed in the Bhagavad-gītā (9.10). The Brahma-saṁhitā affirms that Durgā-śakti is working by the direction of Govinda, and without His sanction the powerful Durgā-śakti cannot move even a blade of grass.
(Srimad Bhagavatam-----2:4:6-----purport).

This adaptability of an organism to different varieties of planets is described in the Brahma-saṁhitā as vibhūti-bhinnam; i.e., each and every one of the innumerable planets within the universe is endowed with a particular type of atmosphere, and the living beings there are more perfectly advanced in science and psychology because of a better atmosphere. Vibhūti means "specific powers," and bhinnam means "variegated." Scientists who are attempting to explore outer space and are trying to reach other planets by mechanical arrangements must know for certain that organisms adapted to the atmosphere of earth cannot exist in the atmospheres of other planets (Easy Journey to Other planets).
(Srimad Bhagavatam-----2:4:8-----purport).

In the Brahma-saṁhitā it is said that the Supreme Absolute Truth, Govinda, the Personality of Godhead, although one without a second, is infallibly expanded by innumerable forms nondifferent from one another, and although He is the original person, He is still ever young with permanent youthful energy. He is very difficult to know simply by learning the transcendental science of the Vedas, but He is very easily realized by His pure devotees.
(Srimad Bhagavatam-----2:4:10-----purport).

In the Brahma-saṁhitā it is said that the Lord, in His transcendental abode Goloka Vṛndāvana, is accustomed to herding the surabhi cows and is served there by hundreds of thousands of goddesses of fortune. All these goddesses of fortune are manifestations of His transcendental pleasure potency (hlādinī-śakti) in His internal energy, and when the Lord manifested Himself on this earth He partially displayed the activities of His pleasure potency in His rāsa-līlā just to attract the conditioned souls, who are all after the phantasmagoria pleasure potency in degraded sex enjoyment.
(Srimad Bhagavatam-----2:4:20-----purport).

There is an intimate relationship between the swan and the lotus stem. So the comparison is very appropriate: without becoming a swan, or paramahaṁsa, one cannot enter into the network of the lotus feet of the Lord. As stated in the Brahma-saṁhitā, the mental speculators, even by dint of learned scholarship, cannot even dream of the Absolute Truth by speculating over it for eternity. The Lord reserves the right of not being exposed to such mental speculators. And because they cannot enter into network stem of the lotus stem of the Lord, all material speculators differ in conclusions, and at the end they make a useless compromise by saying, "as many conclusions, as many ways," according to one's own inclination. (yathā-rucam). But the Lord is not like a shopkeeper trying to please all sorts of customers in the mental speculator exchange.
(Srimad Bhagavatam-----2:4:21-----purport).
