The brahmacārī addressed Vṛkāsura as the son of Śakuni just to convince him that He was known to his father, Śakuni. Vṛkāsura then took the brahmacārī to be someone known to his family, and therefore the brahmacārī’s sympathetic words appealed to him. Before the demon could argue that he had no time to take rest, the Lord informed him about the importance of the body, and the demon was convinced. Any man, especially a demon, takes his body to be very important. Thus Vṛkāsura became convinced about the importance of his body.
Then, just to pacify the demon, the brahmacārī told him, “My dear lord, if you think that you can disclose the mission for which you have taken the trouble to come here, maybe I shall be able to help you so that your purpose will be easily served.” Indirectly, the Lord informed him that because the Lord is the Supreme Brahman, He would certainly be able to adjust the awkward situation created by Lord Śiva.
The demon was greatly pacified by the sweet words of Lord Nārāyaṇa in the form of a brahmacārī, and at last he disclosed all that had happened in regard to the benediction offered by Lord Śiva. The Lord replied to the demon as follows: “I Myself cannot believe that Lord Śiva has in truth given you such a benediction. As far as I know, Lord Śiva is not in a sane mental condition. When he had a quarrel with his father-in-law, Dakṣa, he was cursed to become a piśāca (ghost). Thus he has become the leader of the ghosts and hobgoblins. Therefore I cannot put any faith in his words. But if you still have faith in the words of Lord Śiva, my dear King of the demons, then why don’t you make an experiment by putting your hand on your own head? If the benediction proves false, then you can at once kill this liar, Lord Śiva, so that in the future he will not dare give out false benedictions.”
In this way, by Lord Nārāyaṇa’s sweet words and by the expansion of His superior illusion, the demon became bewildered, and he actually forgot the power of Lord Śiva and his benediction. He was thus very easily persuaded to put his hand on his own head. As soon as the demon did that, his head cracked, as if struck by a thunderbolt, and he immediately died. The demigods from heaven showered flowers on Lord Nārāyaṇa, praising Him with shouts of “All glories!” and “All thanksgiving!” and they offered their obeisances to the Lord. On the death of Vṛkāsura, all the denizens in the higher planetary systems, namely the demigods, the pitṛs, the Gandharvas and the inhabitants of Janaloka, showered flowers on the Personality of Godhead.
Thus Lord Viṣṇu in the form of a brahmacārī released Lord Śiva from the impending danger and saved the whole situation. Lord Nārāyaṇa then informed Lord Śiva that this demon, Vṛkāsura, was killed as the result of his sinful activities. He was especially sinful and offensive because he wanted to experiment on his own master, Lord Śiva. Lord Nārāyaṇa then told Lord Śiva, “My dear lord, a person who commits an offense to great souls cannot continue to exist. He is vanquished by his own sinful activities, and this is certainly true of this demon, who has committed such an offensive act against you.
