Thus spake the Vánar prince, and, stirred With friendly thoughts, Sugríva heard. The light of joy his face o’erspread, And thus to Raghu’s son he said: “O Prince, in rules of duty trained, Caring for all with love unfeigned, Hanúmán’s tongue has truly shown The virtues that are thine alone.

In plain words: Sugriva listens to Hanuman with joy and tells Rama that Hanuman has truly described his good qualities: his training in duty and his real care for everyone.
