Pradyumna: "Obeisances unto the Personality of Godhead, Vāsudeva, directly indicates Lord Śrī Kṛṣṇa, who is the divine son of Vasudeva and Devakī. This fact will be more explicitly explained in the text of this work. Śrī Vyāsadeva asserts herein that Śrī Kṛṣṇa is the original Personality of Godhead, and all others are His direct or indirect plenary portions or portions of the portion."
Prabhupāda: Yes. This will be explained in the Third Chapter of the Śrīmad-Bhāgavatam, First Canto. When describing different incarnations, so in that list of different incarnations, Kṛṣṇa's name is also there. So Vyāsadeva has purposefully explained in that verse that there are so many incarnations. It has been described there that Kṛṣṇa, or God, has got so many incarnations, just like so many waves of the river. If you have got some experience of the flowing river you'll find so many waves are coming, one after another, one after another. He has got so many incarnations that you cannot count even. Just like if you sit down on the bank of a river and go on counting the waves, so whole day and night, whole year, whole life, still, it will not be done.
