Lord is serving to the master. Just like Kṛṣṇa, when He was playing with His friends, so there was sporting, and in the sporting there is defeat and victory. So if some of the friends would become victorious, then the challenge was that one who will be defeated, the victorious person will ride on his shoulder. That was the challenge. So when Kṛṣṇa became defeated, the other boys, they rose up and got up on the shoulder of Kṛṣṇa, and Kṛṣṇa had to carry them.
So although Kṛṣṇa is master, but He became a servant. Just like Kṛṣṇa, when He was playing as a child of Mother Yaśodā, so He was taken with stick, "Kṛṣṇa, if you become again very naughty, then see the stick." So Kṛṣṇa used to cry. There are very nice verses in the Kuntī's prayer, that "The whole universe is afraid of Kṛṣṇa, and Kṛṣṇa is afraid by the stick of Mother Yaśodā." (laughter) Just see. This is Kṛṣṇa. This is spiritual world. When Kṛṣṇa was a little boy playing, Nanda Mahārāja, father of Kṛṣṇa . . . Yaśodā and Nanda Mahārāja, they are foster father and mother. Real mother, father is Vasudeva and Devakī. So Nanda Mahārāja came within the house and saw little Kṛṣṇa, "Yes." He was playing. So Nanda Mahārāja challenged Yaśodāmāyi, "Your Kṛṣṇa can do something work?" "Oh, yes, why not? He can do anything." Immediately, Nanda . . . Yaśodā-mātā, Mother Yaśodā, ordered Kṛṣṇa, "Just carry the wooden slipper of Your father and go there." So Kṛṣṇa immediately took the slipper on His head and brought it to Mahārāja Nanda. Then Nanda Mahārāja said: "Oh, your Kṛṣṇa is very good. Come on, come on, come on." These were, that the childhood pastimes of Kṛṣṇa was enjoyed by the foster father and mother.
Therefore all the sages were surprised that, "What pious activities this Mother Yaśodā did that Kṛṣṇa is completely under her control? Completely." The supreme controller, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1). Kṛṣṇa is the supreme controller. There is no controller of Kṛṣṇa. Kṛṣṇa, the Supreme Lord, govindam ādi-puruṣam, He is the original person. So who can be His father and mother? He is the father of everyone, the supreme father. Sarva-yoniṣu kaunteya sambhavanti mūrtayo yāḥ (BG 14.4). Kṛṣṇa says, "In all species of life, as many forms are there, I am the seed-giving father of all of them." So nobody can be Kṛṣṇa's father. Nobody can be controller of Kṛṣṇa. Nobody can be master of Kṛṣṇa. Kṛṣṇa is the Supreme. Mattaḥ parataraṁ nānyat (BG 7.7): "Nobody is superior than Me." But He accepts inferior position out of love. If you love Kṛṣṇa . . . the Māyāvādī philosophers, they are very much eager to become one with Kṛṣṇa, merge into the existence of Kṛṣṇa. That is their perfection. And Vaiṣṇava philosophy is, "What is there becoming one with Kṛṣṇa? We want to become father of Kṛṣṇa." This is Kṛṣṇa philosophy. "Why I shall be one with my son? We want to become master of Kṛṣṇa." Just like gopīs. Gopīs were addressing Kṛṣṇa with very slanting language, but Kṛṣṇa enjoyed that. That is service to Kṛṣṇa. Kṛṣṇa . . . everyone worships Kṛṣṇa as the Supreme. So sometime Kṛṣṇa becomes disgusted that, "Everyone is coming, simply offering Me respectful obeisances. Nobody comes to chastise Me." So who can chastise Kṛṣṇa? His devotee. Therefore a devotee who comes to the position of chastising Kṛṣṇa, he is more liked by Kṛṣṇa. That is Kṛṣṇa's position.
