Similarly, in Śrīmad-Bhāgavatam there is a description of all kinds of incarnations of the Supreme Personality of Godhead, and there it is said that Kṛṣṇa is not an incarnation of God but is the original Supreme Personality of Godhead Himself. Kṛṣṇas tu bhagavān svayam.
Bhagavad-gītā 11.54, Purport (Translation)
