The Lord bathed Nārada’s feet and then put the water on His own head. Although Lord Kṛṣṇa is the supreme spiritual authority of the universe and the master of His devotees, it was proper for Him to behave in this way, for His name is Brahmaṇya-deva, “the Lord who favors the bṛāhmaṇas.” Thus Śrī Kṛṣṇa honored the sage Nārada by bathing his feet, even though the water that bathes the Lord’s own feet becomes the Ganges, the ultimate holy shrine.
