Within the halo of the universe there is a transcendental planet known as Śvetadvīpa, which is the abode of the Kṣīrodakaśāyī Viṣṇu, the Paramātmā feature of the Supreme Lord. Whenever there is trouble in the universe that cannot be solved by the administrative demigods, they approach Brahmājī for a solution, and if it is not to be solved even by Brahmājī, then Brahmājī consults and prays to the Kṣīrodakaśāyī Viṣṇu for an incarnation and solution to the problems. Such a problem arose when Kaṁsa and others were ruling over the earth and the earth became too much overburdened by the misdeeds of the asuras. Brahmājī, along with other demigods, prayed at the shore of the Kṣīrodaka Ocean, and they were advised of the descent of Kṛṣṇa as the son of Vasudeva and Devakī.
(Srimad Bhagavatam------1:8:34------purport).

When Brahmājī and other demigods want to consult Lord Viṣṇu, the plenary portion of Lord Kṛṣṇa, they have to wait on the shore of the ocean of milk where Lord Viṣṇu is lying on White Land (Śvetadvīpa). This ocean of milk and the Śvetadvīpaplanet are the replica of Vaikuṇṭhaloka within the universe. Neither Brahmājī nor the demigods like Indra can enter into this island of Śvetadvīpa, but they can stand on the shore of the ocean of milk and transmit their message to Lord Viṣṇu, known as Kṣīrodakaśāyī Viṣṇu.
(Srimad Bhagavatam------1:11:8------purport).

The Lord assured Dhruva that he would exist beyond the partial dissolution of this universe. Thus at the end of the complete dissolution, Dhruva Mahārāja would go directly to Vaikuṇṭhaloka, to a spiritual planet in the spiritual sky. Śrīla Viśvanātha Cakravartī Ṭhākura comments in this connection that Dhruvaloka is one of the lokas like Śvetadvīpa, Mathurā and Dvārakā.
(Srimad Bhagavatam------4:9:20-21------purport).

The Lord says, "You will not come back to this material world, for you will reach mat-sthānam, My abode." Therefore Dhruvaloka, or the polestar, is the abode of Lord Viṣṇu within this material world. Upon it there is an ocean of milk, and within that ocean there is an island known as Śvetadvīpa. It is clearly indicated that this planet is situated above the seven planetary systems of the ṛṣis, and because this planet is Viṣṇuloka, it is worshiped by all other planetary systems.
(Srimad Bhagavatam------4:9:25------purport).

There is a Vaikuṇṭhaloka covered with water in this material world, and on that planet is a place called Vedavatī, where Vāsudeva is located. Another planet known as Viṣṇuloka is situated above Satyaloka, and there Saṅkarṣaṇa is present. Similarly, in Dvārakā-purī, Pradyumna is the predominator. On the island known as Śvetadvīpa, there is an ocean of milk, and in the midst of that ocean is a place called Airāvatī-pura, where Aniruddha lies on Ananta.
(Srimad Bhagavatam------5:17:14------purport).

From Saṅkarṣaṇa comes a second Nārāyaṇa expansion, and from this Nārāyaṇa come further expansions of Vāsudeva, Pradyumna, Saṅkarṣaṇa and Aniruddha. The Saṅkarṣaṇa in this group is the original cause of the three puruṣas, namely Kāraṇodakaśāyī Viṣṇu, Garbhodakaśāyī Viṣṇu and Kṣīrodakaśāyī Viṣṇu. Kṣīrodakaśāyī Viṣṇu is situated in every universe in a special planet called Śvetadvīpa. This is confirmed in the Brahma-saṁhitā: aṇḍāntara-stha. The word aṇḍa means this universe. Within this universe is a planet calledŚvetadvīpa, where Kṣīrodakaśāyī Viṣṇu is situated. From Him come all the incarnations within this universe.
(Srimad Bhagavatam------6:16:18-19------purport).

Concerning ajitasya padam, the abode of the Supreme Personality of Godhead in the milk ocean of this material world, Śrīla Viśvanātha Cakravartī Ṭhākura says: padaṁ kṣīrodadhi-stha-śvetadvīpaṁ tamasaḥ prakṛteḥ param. The island known as Śvetadvīpa, which is in the ocean of milk, is transcendental. It has nothing to do with this material world. A city government may have a rest house where the governor and important government officers stay. Such a rest house is not an ordinary house. Similarly, although Śvetadvīpa, which is in the ocean of milk, is in this material world, it is paraṁ padam, transcendental.
(Srimad Bhagavatam------8:5:24------purport).

There (at Śvetadvīpa), Lord Brahmā offered prayers to the Supreme Personality of Godhead, even though he had never seen the Supreme Lord. Simply because Lord Brahmā had heard about the Supreme Personality of Godhead from Vedic literature, with a fixed mind he offered the Lord prayers as written or approved by Vedic literature.
(Srimad Bhagavatam------8:5:25------purport).

It is said that when Brahmā and the other demigods go to see the Supreme Personality of Godhead in Śvetadvīpa, they cannot directly see Him, but their prayers are heard by the Lord, and the needful action is taken. This we have seen in many instances. The word śruta-pūrvāya is significant. We get experience by directly seeing or by hearing.
(Srimad Bhagavatam------8:5:25------purport).

Even though the rascals and fools saw Kṛṣṇa personally, they could not understand that He is the Supreme Personality of Godhead. Even upon seeing God personally, one who is unfortunate cannot understand Him. Therefore we have to hear about God, Kṛṣṇa, from the authentic Vedic literature and from persons who understand the Vedic version properly. Even though Brahmā had not seen the Supreme Personality of Godhead before, he was confident that the Lord was there in Śvetadvīpa. Thus he took the opportunity to go there and offer prayers to the Lord.
(Srimad Bhagavatam------8:5:25------purport).

Those who are obedient to the laws of God are protected by different servants and demigods, whereas those who are undesirable are vanquished by Lord Śiva. Lord Brahmā first met all the demigods, including Lord Śiva. Then, along with mother earth, they went to the shore of the ocean of milk, where Lord Viṣṇu lies on a white island, Śvetadvīpa.
(Srimad Bhagavatam------10:1:19------purport).

It is understood herein that the predominating deity of every planet can see the supreme lord of this universe, Brahmā, whenever there is some disturbance on his planet. And Brahmā can approach the Supreme Lord Viṣṇu, not by seeing Him directly but by standing on the shore of the ocean of milk. There is a planet within this universe called Śvetadvīpa, and on that planet there is an ocean of milk. It is understood from various Vedic scriptures that just as there is the ocean of salt water on this planet, there are various kinds of oceans on other planets.
(Krsna Book).

They chanted as follows: “My dear Kṛṣṇa, may the Lord who is known as Aja protect Your legs; may Lord Maṇimān protect Your knees; may Lord Yajña protect Your thighs; may Lord Acyuta protect Your upper waist; may Lord Hayagrīva protect Your abdomen; may Lord Keśava protect Your heart; may Lord Īśa protect Your chest; may Lord Sūrya protect Your neck; may Lord Viṣṇu protect Your arms; may Lord Urukrama protect Your face; may Lord Īśvara protect Your head; may Lord Cakradhara protect Your front; may Lord Gadādhara protect Your back; may Lord Madhusūdana, who carries a bow in His hand, protect Your right side; may Lord Ajana protect Your left side; may Lord Urugāya with His conchshell protect You on all sides; may the Personality of Godhead Upendra protect You from above; may Lord Tārkṣya protect You on the ground; may Lord Haladhara protect You from all sides; may the Personality of Godhead known as Hṛṣīkeśa protect all Your senses; may Lord Nārāyaṇa protect Your life airs; may the Lord of Śvetadvīpa, Nārāyaṇa, protect the core of Your heart; may Lord Yogeśvara protect Your mind; may Lord Pṛśnigarbha protect Your intelligence; and may the Supreme Personality of Godhead protect Your soul.
(Krsna Book).

There was a great meeting of the denizens of the heavenly planets, and almost all the important brahmacārīs, such as the four Kumāras—Sanandana, Sanaka, Sanātana and Sanat-kumāra—attended. Their discussion was on the subject matter of understanding the Absolute Truth, Brahman. You were not present at that meeting because you had gone to see My expansion Aniruddha, who lives on the island of Śvetadvīpa. In this meeting, all the great sages and brahmacārīs very elaborately discussed the point about which you have asked Me, and their discussion was very interesting. It was so delicate that even the Vedas were unable to answer the intricate questions raised.
(Krsna Book).

East of Sumeru is the ocean of milk, in which there is a white city on a white island where the Lord can be seen sitting with His consort, Lakṣmījī, on a throne of Śeṣa. That feature of Viṣṇu also enjoys sleeping during the four months of the rainy season. The Śvetadvīpa in the milk ocean is situated just south of the ocean of salt water. It is calculated that the area of Śvetadvīpa is 200,000 square miles. This transcendentally beautiful island is decorated with desire trees to please Lord Viṣṇu and His consort.” There are references to Śvetadvīpa in the Brahmāṇḍa Purāṇa, Viṣṇu Purāṇa, Mahābhārata and Padma Purāṇa
(Sri Caitanya Caritamrta------1:5:112------purport).

The Lord of Śvetadvīpa expands Himself as Śeṣa Nāga, who sustains all the planets upon His innumerable hoods. These huge global spheres are compared to grains of mustard resting on the spiritual hoods of Śeṣa Nāga. The scientists' law of gravity is a partial explanation of Lord Saṅkarṣaṇa's energy. The name "Saṅkarṣaṇa" has an etymological relationship to the idea of gravity.
(Sri Caitanya Caritamrta------1:5:119------purport).

In the Brahmāṇḍa Purāṇa it is said, "The same Personality of Godhead who is known in Vaikuṇṭha as the four-handed Nārāyaṇa, the friend of all living entities, and in the milk ocean as the Lord of Śvetadvīpa, and who is the best of all puruṣas, appeared as the son of Nanda. In a fire there are many sparks of different dimensions; some of them are very big, and some are small. The small sparks are compared to the living entities, and the large sparks are compared to the Viṣṇu expansions of Lord Kṛṣṇa. All the incarnations emanate from Kṛṣṇa, and after the end of their pastimes they again merge with Kṛṣṇa."
(Sri Caitanya Caritamrta------1:5:132------purport).
