When Kṛṣṇa entered the cave of the hill, Kālayavana followed, chastising Him with various harsh words. Kṛṣṇa suddenly disappeared from the demon’s sight, but Kālayavana followed and also entered the cave. The first thing he saw was a man lying down asleep within the cave. Kālayavana was eager to fight with Kṛṣṇa, and when he could not see Kṛṣṇa but instead saw only a man lying down, he thought that Kṛṣṇa was sleeping within the cave. Kālayavana was very much puffed up and proud of his strength, and he thought Kṛṣṇa was avoiding the fight. Therefore, he strongly kicked the sleeping man, thinking him to be Kṛṣṇa. The sleeping man had been lying down for a very long time. When awakened by the kicking of Kālayavana, he immediately opened his eyes and began to look around in all directions. At last he saw Kālayavana standing nearby. The man had been untimely awakened and was therefore very angry, and when he looked upon Kālayavana in his angry mood, rays of fire emanated from his eyes, and Kālayavana burned to ashes within a moment.
When Mahārāja Parīkṣit heard this incident of Kālayavana’s being burned to ashes, he inquired about the sleeping man from Śukadeva Gosvāmī: “Who was he? Why was he sleeping there? How had he achieved so much power that instantly, by his glance, Kālayavana was burned to ashes? How did he happen to be lying down in the cave of the hill?” He put many questions before Śukadeva Gosvāmī, and Śukadeva answered as follows.
“My dear King, this person was born in the very great family of King Ikṣvāku, in which Lord Rāmacandra was also born, and he happened to be the son of a great king known as Māndhātā. He himself was also a great soul and was known popularly as Mucukunda. King Mucukunda was a strict follower of the Vedic principles of brahminical culture, and he was truthful to his promise. He was so powerful that even demigods like Indra used to ask him to help in fighting the demons, and as such he often fought against the demons to protect the demigods.”
The commander in chief of the demigods, known as Kārttikeya, was satisfied with the fighting of King Mucukunda, but once he asked that the King, having taken too much trouble in fighting the demons, retire from fighting and take rest. Kārttikeya addressed King Mucukunda, “My dear King, you have sacrificed everything for the sake of the demigods. You had a very nice kingdom, undisturbed by any kind of enemy. But you left that kingdom, neglected your opulence and possessions, and never cared for fulfillment of your personal ambitions. Due to your long absence from your kingdom while fighting the demons on behalf of the demigods, your queen, your children, your relatives and your ministers have all passed away in due course of time. Time and tide wait for no man. Now even if you return to your home, you will find no one living there. The influence of time is very strong. Time is so powerful because it is a representation of the Supreme Personality of Godhead; time is therefore stronger than the strongest. The influence of time can effect changes in subtle things without difficulty. No one can check the progess of time. As an animal tamer tames animals according to his will, time also adjusts things according to its own will. No one can supersede the arrangement made by supreme time.”
Thus addressing Mucukunda, the demigod requested him to ask any benediction he might be pleased with, except the benediction of liberation. Liberation cannot be awarded by any living entity but the Supreme Personality of Godhead, Viṣṇu. Therefore another name of Lord Viṣṇu or Kṛṣṇa is Mukunda, “He who can award liberation.”
King Mucukunda had not slept for many, many years. He was engaged in the duty of fighting, and therefore he was very tired. So when the demigod offered a benediction, Mucukunda simply thought of sleeping. He replied as follows: “My dear Kārttikeya, best of the demigods, I want to sleep now, and I want from you the following benediction. Grant me the power to burn to ashes, by my mere glance, anyone who disturbs my sleeping and awakens me untimely. Please give me this benediction.” The demigod agreed and also gave him the benediction that he would be able to take complete rest. Then King Mucukunda entered the cave of the mountain.
