Son of Devaki (Books)
Bhagavad-gita As It Is
BG Chapters 1 - 6
BG 4.4, Purport:
As it will be evident from the Tenth Chapter, Arjuna knew perfectly well that Kṛṣṇa is the Supreme Personality of Godhead, the fountainhead of everything and the last word in transcendence. Of course, Kṛṣṇa also appeared as the son of Devakī on this earth. How Kṛṣṇa remained the same Supreme Personality of Godhead, the eternal original person, is very difficult for an ordinary man to understand. Therefore, to clarify this point, Arjuna put this question before Kṛṣṇa so that He Himself could speak authoritatively.
