CC Madhya 10.112

grantha, śloka, gīta keha prabhu-pāśe āne
svarūpa parīkṣā kaile, pāche prabhu śune
Word for word: 
grantha — scriptures; śloka — verses; gīta — songs; keha — anyone; prabhu-pāśe — to Śrī Caitanya Mahāprabhu; āne — brings; svarūpa — Svarūpa Dāmodara; parīkṣā kaile — after he examined; pāche — later; prabhu — Śrī Caitanya Mahāprabhu; śune — hears.
Translation: 
If someone wrote a book or composed verses and songs and wanted to recite them before Śrī Caitanya Mahāprabhu, Svarūpa Dāmodara would first examine them and then correctly present them. Only then would Śrī Caitanya Mahāprabhu agree to listen.
