Śrīmad-Bhāgavatam
[Canto 4, Ch. 9]
PURPORT
The word  sahasraśīrṣa  refers to the Personality of Godhead known as Garbhodakaśāyī Viṣṇu. Although the Lord appeared as Kṣīrodakaśāyī Viṣṇu, He has been described here as Sahasraśīrṣa Viṣṇu because He is non-different from Garbhodakaśāyī Viṣṇu. According to Śrīla Sanātana Gosvāmī in his  Bhāgavatāmṛta , the Sahasraśīrṣa Personality of Godhead who appeared at that time was the incarnation known as Pṛśnigarbha. He created the planet known as Dhruvaloka for the habitation of Dhruva Mahārāja.

TRANSLATION
The form of the Lord, which was brilliant like lightning and in which Dhruva Mahārāja, in his mature yogic process, was fully absorbed in meditation, all of a sudden disappeared. Thus Dhruva was perturbed, and his meditation broke. As soon as he opened his eyes he saw the Supreme Personality of Godhead personally present, just as he had been seeing Him in his heart.
PURPORT
Because of his mature position in yogic meditation, Dhruva Mahārāja was constantly observing the form of the Personality of Godhead within
