sah -- he, Kalayavana; tavat -- that much; tasya -- of him, the awakened man; rushtasya -- who was angered; drishti -- of the glance; patena -- by the casting; bharata -- O descendant of Bharata (Parikshit Maharaja); deha-jena -- generated in his own body; agnina -- by the fire; dagdhah -- burned; bhasma-sat -- to ashes; abhavat -- he was; kshanat -- in a moment.
The man who incinerated Kalayavana with his glance was named Mucukunda. As he will explain to Lord Krishna, he had fought for a long time on behalf of the demigods, finally taking as his benediction the right to sleep undisturbed. The Hari-vamsa explains that he secured the further benediction of being able to destroy anyone who disturbed his sleep. Acarya Visvanatha Cakravarti Thakura quotes from the Sri Hari-vamsa as follows:
prasuptam bodhayed yo mam
tam daheyam aham surah
cakshusha krodha-diptena
evam aha punah punah
"Again and again Mucukunda said, 'O demigods, with eyes blazing with anger, may I incinerate anyone who awakens me from sleep.' "
Srila Visvanatha Cakravarti explains that Mucukunda made this rather morbid request to scare Lord Indra, who, Mucukunda thought, might otherwise wake him repeatedly to request his help in fighting Indra's cosmic enemies. Indra's consent to Mucukunda's request is described in Sri Vishnu Purana as follows:
proktas ca devaih samsuptam
yas tvam utthapayishyati
deha-jenagnina sadyah
sa tu bhasmi-karishyati
"The demigods declared, 'Whoever awakens you from sleep will suddenly be burnt to ashes by a fire generated from his own body.' "
