Srimad Bhagavatam Canto 02, Chapter 08, Text 26

SB 2.8.26

na me ’savah parayanti
brahmann anasanad ami
pibato ’cyuta-piyusam
tad vakya-abdhi-vinihsrtam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
O learned brahmana, because of my drinking the nectar of the message of the infallible Personality of Godhead, which is flowing down from the ocean of your speeches, I do not feel any sort of exhaustion due to my fasting.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
The disciplic succession from Brahma, Narada, Vyasa and Sukadeva Gosvami is particularly different from others. The disciplic successions from other sages are simply a waste of time, being devoid of acyuta-katha, or the message of the infallible Lord. The mental speculators can present their theories very nicely by reason and arguments, but such reasons and arguments are not infallible, for they are defeated by better mental speculators. Maharaja Pariksit was not interested in the dry speculation of the flickering mind, but he was interested in the topics of the Lord because factually he felt that by hearing such a nectarean message from the mouth of Sukadeva Gosvami he was not feeling any exhaustion, even though he was fasting because of his imminent death.
One can indulge in hearing the mental speculators, but such hearing cannot endure for any length of time. One will be exhausted very soon from hearing such hackneyed ways of thinking, and no one in the world can be satisfied simply by hearing such useless speculations. The message of the Lord, especially from a personality like Sukadeva Gosvami, can never be tiring, even though one may be exhausted from other causes.
In some editions of the Srimad-Bhagavatam, the text of the last line of this verse reads anyatra kupitad dvijat, which means that the King might be overwhelmed by the thought of his imminent death by snakebite. The snake is also twice-born, and its anger is compared to the cursing brahmana boy who was without good intelligence. Maharaja Pariksit was not at all afraid of death, for he was fully encouraged by the message of the Lord. One who is fully absorbed in acyuta-katha can never be afraid of anything in this world.
