CC Madhya 19.117
sarva-tattva-nirūpaṇe ‘pravīṇa’ karilā
By entering the heart of Rūpa Gosvāmī, Śrī Caitanya Mahāprabhu empowered him to ascertain properly the conclusions of all truths. He made him an experienced devotee whose decisions correctly agreed with the verdicts of the disciplic succession. Thus Śrī Rūpa Gosvāmī was personally empowered by Śrī Caitanya Mahāprabhu.
The principles of devotional service are only apparently under the jurisdiction of material activity. To be rightly guided, one must be personally guided by Śrī Caitanya Mahāprabhu. This was the case with Śrīla Rūpa Gosvāmī, Sanātana Gosvāmī and other ācāryas.
