tatra mam anumoderan
devas tri-bhuvanesvarah
muhurtena brahma-lokam
khatvangah samasadhayat
Translation:
Thus may the presiding demigods of these three worlds kindly show their mercy upon me. Indeed, Maharaja Khatvanga was able to achieve the spiritual world in a single moment.
Purport:
The brahmana of Avanti thought that although he was an old man who might die at any moment he could follow the example of Maharaja Khatvanga, who achieved the Lord’s mercy in a single moment. Maharaja Khatvanga, as described in the Second Canto of Srimad-Bhagavatam, fought valiantly on behalf of the demigods, and they offered the king any benediction he might desire. Khatvanga Maharaja chose to find out the remaining duration of his life, which unfortunately was a single moment. The king therefore immediately surrendered to Lord Krsna and achieved the spiritual world. The brahmana of Avanti desired to follow this example; with the blessings of the demigods, who are all devotees of the Lord, he hoped to become fully Krsna conscious before giving up his body.
