Hanuman entered the harem of Ravana surrounded by walls of gold inlaid with precious pearls and other gems and sprinkled with excellent black agaru and sandal water. इत्यार्षे श्रीमद्रामायणे वाल्मीकीय आदिकाव्ये सुन्दरकाण्डे चतुर्थस्सर्गः।। Thus ends the fourth sarga of Sundarakanda of the holy Ramayana, the first epic composed by sage Valmiki.
