In the Brahma-saṁhitā it is clearly stated that the Supreme Personality of Godhead is the cause of all causes. There are undoubtedly many demigods, the chiefs of whom are Brahmā and Śiva. Lord Viṣṇu is the Lord of Brahmā and Śiva, not to speak of the brāhmaṇas in this material world.
(Srimad Bhagavatam-----3:16:17-----purport).

It is said in the Brahma-saṁhitā that the Lord is always served by many hundreds of thousands of goddesses of fortune in His Vaikuṇṭha planet, yet because of His attitude of renunciation of all opulences, He is not attached to any one of them.
(Srimad Bhagavatam-----3:16:21-----purport).

In this verse the Lord is addressed as Keśava because He killed the demon Keśī in the beginning of creation. Keśava is also a name of Kṛṣṇa. Kṛṣṇa is the origin of all incarnations, and it is confirmed in Brahma-saṁhitā that Govinda, the Supreme Personality of Godhead, the cause of all causes, exists simultaneously in His different incarnations and expansions.
(Srimad Bhagavatam-----3:19:24-----purport).

The Lord is spoken of herewith as the origin of the boar species. As stated in the Vedānta-sūtra (1.1.2), the Absolute Truth is the origin of everything. Therefore it is to be understood that all 8,400,000 species of bodily forms originate from the Lord, who is always ādi, or the beginning. In Bhagavad-gītā Arjuna addresses the Lord as ādyam, or the original. Similarly, in the Brahma-saṁhitā the Lord is addressed as ādi-puruṣam, the original person. Indeed, in Bhagavad-gītā (10.8) the Lord Himself declares, mattaḥ sarvaṁ pravartate: "From Me everything proceeds."
(Srimad Bhagavatam-----3:19:31-----purport).

The Māyāvādī philosophers think that although all these forms are assumed by the Lord just as the devotees desire to see Him, actually He is impersonal. FromBrahma-saṁhitā, however, we can understand that this is not so, for the Lord has multiforms. It is said in the Brahma-saṁhitā, advaitam acyutam. The Lord does not appear before the devotee because of the devotee's imagination. Brahma-saṁhitā further explains that the Lord has innumerable forms: rāmādi-mūrtiṣu kalā-niyamena tiṣṭhan (Bs. 5.39). He exists in millions and millions of forms. There are 8,400,000 spieces of living entities, but the incarnations of the Supreme Lord are innumerable. In the Bhāgavatam it is stated that as the waves in the sea cannot be counted but appear and disappear continually, the incarnations and forms of the Lord are innumerable.
(Srimad Bhagavatam-----3:20:25-----purport).

The process of Kṛṣṇa consciousness is to deliver the form of Kṛṣṇa directly. The form of Kṛṣṇa is described in the authoritative Vedic literature Brahma-saṁhitā: His abode is made of cintāmaṇi stone, and the Lord plays there as a cowherd boy and is served by many thousands of gopīs. These descriptions are authoritative, and a Kṛṣṇa conscious person takes them directly, acts on them, preaches them and practices devotional service as enjoined in the authoritative scriptures.
(Srimad Bhagavatam-----3:21:11-----purport).

This is very nicely explained in the Brahma-saṁhitā (5.46): dīpārcir eva hi daśāntaram abhyupetya. With one candle one may light a second candle, with the second a third and then a fourth, and in this way one can light up thousands of candles, and no candle is inferior to another in distributing light.
(Srimad Bhagavatam-----3:21:32-----purport).

In the Brahma-saṁhitā (5.40) it is similarly stated, vibhūti-bhinnam: on each and every planet there are different opulences. It cannot be expected that one planet is exactly like another. By God's grace, by nature's law, each and every planet is made differently and has different wonderful features.
(Srimad Bhagavatam-----3:23:43-----purport).

The Supreme Personality of Godhead, however, can expand Himself into millions of forms, ananta-rūpa—innumerable, countless forms—as stated in the Brahma-saṁhitā. No one can compare to the Supreme Personality of Godhead by any conceivable energetic manifestation of power.
(Srimad Bhagavatam-----3:23:44-----purport).

In the Brahma-saṁhitā it is stated that the Lord is one Absolute, but He has ananta, or innumerable, forms. Advaitam acyutam anādim ananta-rūpam (Bs. 5.33). The Lord is the original form, but still He has multiforms. Those multiforms are manifested by Him transcendentally, according to the tastes of His multidevotees.
(Srimad Bhagavatam-----3:24:31-----purport).

When we say "Kṛṣṇa" we refer to all forms of the Lord—not only Kṛṣṇa, but Rāma, Nṛsiṁha, Varāha, Nārāyaṇa, etc. The varieties of transcendental forms exist simultaneously. That is also stated in the Brahma-saṁhitā: rāmādi-mūrtiṣu. .. nānāvatāram. He already exists in multiforms, but none of the forms are material. Śrīdhara Svāmī has commented that arūpiṇaḥ, "without form," means without material form.
(Srimad Bhagavatam-----3:24:31-----purport).

There are full literatures describing these activities of the Lord, especially Bhagavad-gītā, Brahma-saṁhitā and Śrīmad-Bhāgavatam. The sincere devotee who associates with devotees gets the opportunity to hear and contemplate this subject of the pastimes of the Lord, and the result is that he feels distaste for so-called happiness in this or that world, in heaven or on other planets.
(Srimad Bhagavatam-----3:25:26-----purport).

If we examine all persons, we will find that everyone has a beginning, but when we approach a person who has no beginning, He is the Supreme Person. That is the definition given in the Brahma-saṁhitā. Īśvaraḥ paramaḥ kṛṣṇaḥ: (Bs. 5.1) the Supreme Personality of Godhead is Kṛṣṇa, the supreme controller; He is without beginning, and He is the beginning of everyone. This definition is found in all Vedic literatures.
(Srimad Bhagavatam-----3:26:3-----purport).

Similarly, brahmajyoti, the spiritual effulgence, is a reflection of the body of the Supreme Lord. This is confirmed in the Brahma-saṁhitā: yasya prabhā prabhavataḥ (Bs. 5.40). The brahmajyoti, or Brahman effulgence, is due to His bodily luster. Therefore it is said here, svayaṁ-jyotiḥ: He Himself is light. His light is distributed in different ways, as the brahmajyoti, as sunlight and as moonlight.
(Srimad Bhagavatam-----3:26:3-----purport).

The Brahma-saṁhitā (5.37) confirms this. Goloka eva nivasaty akhilātma-bhūtaḥ: He is living in Goloka, but still He is present all over the creation. He is the Supersoul of everything, the Supreme Personality of Godhead, and He has innumerable transcendental qualities. It is also concluded that although He is undoubtedly a person, He is not a puruṣa of this material world.
(Srimad Bhagavatam-----3:26:3-----purport).

In the Brahma-saṁhitā there is description of Lord Kṛṣṇa's lands, the variegatedness of the spiritual abode, and the forms of the Lord playing a flute with His spiritual body. All these forms are described in the scriptures, and when they are thus presented they become worshipable.
(Srimad Bhagavatam-----3:26:46-----purport).

This entrance of the Supreme Personality of Godhead involves His entering even the atoms of the material world. This is confirmed in the Brahma-saṁhitā (5.35): aṇḍāntara-stha-paramāṇu-cayāntara-stham. He is not only within the universe, but within the atoms also. He is within the heart of every living entity. Garbhodakaśāyī Viṣṇu, the Supreme Personality of Godhead, entered into everything.
(Srimad Bhagavatam-----3:26:50-----purport).

This virāṭ-puruṣa is considered an incarnation of the Lord. The original form of the Lord is Kṛṣṇa, as confirmed in Brahma-saṁhitā: ādi-puruṣa. The virāṭ-puruṣa is also puruṣa, but He is not ādi-puruṣa. The ādi-puruṣa is Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ/ anādir ādir govindaḥ (Bs. 5.1). In Bhagavad-gītā Kṛṣṇa is also accepted as the ādi-puruṣa, the original.
(Srimad Bhagavatam-----3:26:52-----purport).

The senses appear, and over each of them there is a presiding deity. It is corroborated by this statement of Śrīmad-Bhāgavatam, and also by Brahma-saṁhitā, that the sun appeared after the appearance of the eyes of the universal form of the Lord. The sun is dependent on the eyes of the universal form. The Brahma-saṁhitā also says that the sun is the eye of the Supreme Personality of Godhead, Kṛṣṇa. Yac-cakṣur eṣa savitā. Savitā means "the sun."
(Srimad Bhagavatam-----3:26:55-----purport).

As soon as he remembers the energy of Kṛṣṇa, he immediately remembers Kṛṣṇa in His personal form. Therefore in all his observations he sees Kṛṣṇa only. In theBrahma-saṁhitā (5.38) it is stated that when one's eyes are smeared with love of Kṛṣṇa (premāñjana-cchurita), he always sees Kṛṣṇa, outside and inside. This is confirmed here; one should be freed from all other vision, and in that way he is freed from the false egoistic identification and sees himself as the eternal servitor of the Lord.
(Srimad Bhagavatam-----3:27:10-----purport).

It is confirmed in Bhagavad-gītā that the background of the material manifestation is Lord Kṛṣṇa. And, as confirmed in the Brahma-saṁhitā, Kṛṣṇa is the cause of all causes. In the Brahma-saṁhitā it is stated that the Supreme Lord, by His partial or plenary expansion, is present not only within this universe and each and every universe, but in every atom, although He is one without a second.
(Srimad Bhagavatam-----3:27:11-----purport).

People always ask why Kṛṣṇa is blue. The color of the Lord has not been imagined by an artist. It is described in authoritative scripture. In the Brahma-saṁhitā also, the color of Kṛṣṇa's body is compared to that of a bluish cloud. The color of the Lord is not poetical imagination. There are authoritative descriptions in the Brahma-saṁhitā, Śrīmad-Bhāgavatam, Bhagavad-gītā and many of the purāṇas of the Lord's body, His weapons and all other paraphernalia. The Lord's appearance is described here as padma-garbhāruṇekṣaṇam.
(Srimad Bhagavatam-----3:28:13-----purport).

It is not that He appears beautiful to the devotees but is ultimately impersonal. Śaśvat means "ever existing." That beauty is not temporary. It is ever existing—He is always youthful. In the Brahma-saṁhitā (5.33) it is also stated: advaitam acyutam anādim ananta-rūpam ādyaṁ purāṇa-puruṣaṁ nava-yauvanaṁ ca. The original person is one without a second, yet He never appears old; He always appears as ever fresh as a blooming youth.
(Srimad Bhagavatam-----3:28:17-----purport).

This is confirmed in the Brahma-saṁhitā: a person who has developed pure love for the Lord, and whose eyes are smeared with the ointment of transcendental loving exchange, always sees within his heart the Supreme Personality of Godhead. The devotees especially see the Lord in the beautiful blackish form of Śyāmasundara.
(Srimad Bhagavatam-----3:28:18-----purport).
