Kiskindhākānda - Canto 11

With a view to ascertaining Śrī Rāma's actual strength, Sugrīva expatiates on the prowess of Vālī and tells him how Māyāvī's brother, the demon Dundubhi too challenged him to a duel and how, having made short work of him, Vālī listlessly hurled his dead body crossing over to the precincts of the hermitage of Sage Matanga, and how the site of the hermitage having been desecrated with blood, spattered here and there from itís mouth, Sage Matanga pronounced a curse forbidding the individual who had perpetrated the sacrilege to enter the hermitage on pain of death, thus enabling Sugīva to live unmolested in that retreat. In order to convince Sugrīva of his superior might Śrī Rāma kicks the skeleton of Dundubhi away with his toe. Belittling this feat on the ground of the skeleton havng shrunk as a result of exposure, Sugrīva further asks Śrī Rāma to pierce with his arrow one of the seven sal trees standing there and thus demonstrate his strength.
