When Dhruva Mahārāja, the son of the King, was thus advised by the great sage Nārada, he circumambulated Nārada, his spiritual master, and offered him respectful obeisances. Then he started for Madhuvana, which is always imprinted with the lotus footprints of Lord Kṛṣṇa and which is therefore especially auspicious.
