Transliteration
tava kathāmṛtaṃ taptajīvanaṃkavibhirīḍitaṃ kalmaṣāpahamśravaṇamaṅgalaṃ śrīmadātataṃbhuvi gṛṇanti ye bhūridā janāḥ
The nectar of your story gives life to the afflicted. Praised by poets, it removes wrongdoing, blesses those who hear it, and spreads its radiance. Those who sing it on earth are generous givers.
Original King of Dwarka translationReflection inspired by Srimad Bhagavatam 10.31.9
In absence, a story can keep a relationship audible. The singers call its telling a gift, something received and then offered again.
Source & context
The gopis sing collectively; not an individual quotation by Radha. From the collective song of the gopis. The passage does not name Radha as its individual speaker.
