"When will Srila Rupa Gosvami Prabhupada, who has established within this material world the mission to fulfill the desire of Lord Caitanya, give me shelter under his lotus feet?"
The special function of Srila Rupa Gosvami is to establish the feelings of Sri Caitanya Mahaprabhu. These feelings are His desires that His special mercy be spread throughout the world in this Kali-yuga.
