Sunderkand is a chapter in the Hindu epic Valmiki’s Ramayana which narrates the glory of Lord Hanuman about how he jumps across the sea, goes to Lanka and meets Mata Sita in Ashoka Vatika. There are various other scenes, like one such scene where the demons try putting fire to Hanuman ji’s tale but instead end up setting fire to Lanka itself. There are various dialogues in Sunderkand which are a good read.
