Srimad-Bhagavatam

SB Canto 3

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.

SB 3.27.11, Translation and Purport

A liberated soul realizes the Absolute Personality of Godhead, who is transcendental and who is manifest as a reflection even in the false ego. He is the support of the material cause and He enters into everything. He is absolute, one without a second, and He is the eyes of the illusory energy.

A pure devotee can see the presence of the Supreme Personality of Godhead in everything materially manifested. He is present there only as a reflection, but a pure devotee can realize that in the darkness of material illusion the only light is the Supreme Lord, who is its support. 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. The word advayam, "without a second," which is used in this verse, indicates that although the Supreme Personality of Godhead is represented in everything, including the atoms, He is not divided. His presence in everything is explained in the next verse.
