Just like in our material experience we see the master is always master and the servant is always servant. But in the spiritual world, sometimes the master is the servant also. This is called Absolute, Absolute world. Here there is distinction between master and the servant, but in the spiritual world there is no such distinction. Sometimes the servant is rendering service to the Lord, and sometimes the 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.
