Valmiki Ramayana 7.40.20

एवमेतत्कपिश्रेष्ठ भविता नात्र संशयः ।चरिष्यति कथा यावदेषा लोके च मामिका ।तावत्ते भविता कीर्तिः शरीरे ऽप्यसवस्तथा॥

evametatkapiśreṣṭha bhavitā nātra saṃśayaḥ |cariṣyati kathā yāvadeṣā loke ca māmikā |tāvatte bhavitā kīrtiḥ śarīre 'pyasavastathā ||

Our plain-language meaning of this verse is waiting for scholar review.
