Caitanya-caritāmṛta 7.13
viśvarūpa-siddhi-prāpti jānena sakala dakṣiṇa-deśa uddhārite karena ei chala
[vishvaroopa-siddhi-praapti jaanena sakala dakshina-desha uddhaarite karena ei chala]
Blended reading (Sanskrit + English inline)
viśvarūpa-siddhi-prāpti jānena sakala dakṣiṇa-deśa uddhārite karena ei chala
Knowing everything, Śrī Caitanya Mahāprabhu was aware that Viśvarūpa had already passed away. A pretense of ignorance was necessary, however, so that He could go to South India and liberate the people there.
