CC Madhya 25.143-144, Translation and Purport:

“"The meaning of the Vedānta-sūtra is present in Śrīmad-Bhāgavatam. The full purport of the Mahābhārata is also there. The commentary of the Brahma-gāyatrī is also there and fully expanded with all Vedic knowledge. Śrīmad-Bhāgavatam is the supreme Purāṇa, and it was compiled by the Supreme Personality of Godhead in His incarnation as Vyāsadeva. There are twelve cantos, 335 chapters and eighteen thousand verses."

This is a quotation from the Garuḍa Purāṇa.

CC Madhya 25.147, Translation:

“In the beginning of Śrīmad-Bhāgavatam there is an explanation of the Brahma-gāyatrī mantra. "The Absolute Truth (satyaṁ param)" indicates the relationship, and "we meditate (dhīmahi) on Him" indicates the execution of devotional service and the ultimate goal of life.

SB Canto 5

N the Gāyatrī mantra, we chant, oṁ bhūr bhuvaḥ svaḥ tat savitur vareṇyam. Above the Bhūloka planetary system is Bhuvarloka, and above that is Svargaloka, the heavenly planetary system. All these planetary systems are controlled by Savitā, the sun-god.

SB 5.1.31, Translation and Purport:

When Priyavrata drove his chariot behind the sun, the rims of his chariot wheels created impressions that later became seven oceans, dividing the planetary system known as Bhū-maṇḍala into seven islands.

Sometimes the planets in outer space are called islands. We have experience of various types of islands in the ocean, and similarly the various planets, divided into fourteen lokas, are islands in the ocean of space. As Priyavrata drove his chariot behind the sun, he created seven different types of oceans and planetary systems, which altogether are known as Bhū-maṇḍala, or Bhūloka. In the Gāyatrī mantra, we chant, oṁ bhūr bhuvaḥ svaḥ tat savitur vareṇyam. Above the Bhūloka planetary system is Bhuvarloka, and above that is Svargaloka, the heavenly planetary system. All these planetary systems are controlled by Savitā, the sun-god. By chanting the Gāyatrī mantra just after rising early in the morning, one worships the sun-god.
