rūpa kahe, — “mahāprabhura śravaṇecchā jāni”
Śrī Rūpa replied, “I think that Śrī Caitanya Mahāprabhu’s desire to hear is prarocanā.
The method of inducing the audience to become more and more eager to hear by praising the time and place, the hero and the audience is called prarocanā. This is the statement regarding prarocanā in the Nāṭaka-candrikā:
deśa-kāla-kathā-vastu- sabhyādīnāṁ praśaṁsayā
śrotṝṇām unmukhī-kāraḥ kathiteyaṁ prarocanā
Similarly, the Sāhitya-darpaṇa (6.286) says:
tasyāḥ prarocanā vīthī tathā prahasanā-mukhe
aṅgānyatronmukhī-kāraḥ praśaṁsātaḥ prarocanā
Any literature presented in Sanskrit must follow the rules and regulations mentioned in the authoritative reference books. The technical inquiries by Śrīla Rāmānanda Rāya and the replies of Śrīla Rūpa Gosvāmī indicate that both of them were expert and fully conversant with the techniques of writing drama.
