Srimad Bhagavatam Canto 09, Chapter 21, Text 11

SB 9.21.11

tasya tam karunam vacam
 nisamya vipula-sramam
krpaya bhrsa-santapta
 idam ahamrtam vacah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Aggrieved at hearing the pitiable words of the poor fatigued candala, Maharaja Rantideva spoke the following nectarean words.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Maharaja Rantideva’s words were like amrta, or nectar, and therefore, aside from rendering bodily service to an aggrieved person, by his words alone the King could save the life of anyone who might hear him.
