Caitanya-caritāmṛta 11.19
vāsudeva gīte kare prabhura varṇane kāṣṭha-pāṣāṇa drave yāhāra śravaṇe
[vaasudeva geete kare prabhura varnane kaashtha-paashaana drave yaahaara shravane]
Blended reading (Sanskrit + English inline)
vāsudeva gīte kare prabhura varṇane kāṣṭha-pāṣāṇa drave yāhāra śravaṇe
When Vāsudeva Ghoṣa described Lord Caitanya and Nityānanda while performing kīrtana, even wood and stone would melt upon hearing it.
