SB 10.31.9
tava kathamrtam tapta-jivanam
kavibhir iditam kalmasapaham
sravana-mangalam srimad atatam
bhuvi grnanti ye bhuri-da janah
Translation:
The nectar of Your words and the descriptions of Your activities are the life and soul of those suffering in this material world. These narrations, transmitted by learned sages, eradicate one’s sinful reactions and bestow good fortune upon whoever hears them. These narrations are broadcast all over the world and are filled with spiritual power. Certainly those who spread the message of Godhead are most munificent.
Purport:
King Prataparudra recited this verse to Sri Caitanya Mahaprabhu during Lord Jagannatha’s Ratha-yatra festival. While the Lord was resting in a garden, King Prataparudra humbly entered and began massaging His legs and lotus feet. Then the King recited the Thirty-first Chapter of the Tenth Canto of the Srimad-Bhagavatam, the songs of the gopis. The Caitanya-caritamrta relates that when Lord Caitanya heard this verse, beginning tava kathamrtam, He immediately arose in ecstatic love and embraced King Prataparudra. The incident is described in detail in the Caitanya-caritamrta (Madhya 14.4-18), and in his edition Srila Prabhupada has given extensive commentary on it.
