Lecture Excerpt — Los Angeles, February 9, 1969: Kṛṣṇa is the perfect name. God has no name; some philosophers say like that. No name means that His name is understood by His different action. Just like Kṛṣṇa is sometimes called Yaśodā-nandana. Because He has accepted mother Yaśodā, to become her son, therefore Kṛṣṇa’s name is Yaśodā-nandana. Kṛṣṇa’s name is Pārtha-sārathi. Why? Because Kṛṣṇa has accepted to become a chariot driver of Arjuna. Pārtha means Arjuna, and sārathi means chariot driver. So Kṛṣṇa’s name became Pārtha-sārathi. Kṛṣṇa used to steal butter from the stock of His mother’s butter stock; therefore Kṛṣṇa’s name is Mākhana-cora. So in this way Kṛṣṇa’s name are varieties. Kṛṣṇa has unlimited number of activities, and according to such activity He has got unlimited names. But the primary name which is applicable in all circumstances is “Kṛṣṇa.” Kṛṣṇa means “all-attractive.” Kṛṣṇa attracts everyone.
