Bâlmîki-Âsrama—Bithur, fourteen miles from Cawnpur, which was the hermitage of Ṛishi Vâlmîki, the author of the Râmâyaṇa. Sîtâ, the wife of Râmachandra, lived at the hermitage during her exile, where she gave birth to the twin sons, Lava and Kuśa. The temple erected in honour of Vâlmîki at the hermitage is situated on the bank of the Ganges (Râmâyaṇa, Uttara, ch. 58). Sîtâ is said to have been landed by Lakshmana, while conveying her to the hermitage, at the Satî-ghât in Cawnpur. A large heavy metallic spear or arrow-head of a greenish colour is shown in a neighbouring temple close to the Brahmâvartta-ghât at Bithur, also situated on the bank of the Ganges, as the identical arrow with which Lava wounded his father, Râmachandra, in a fight for the Aśvamedha horse; this arrow-head is said to have been discovered a few years ago in the bed of the river Ganges in front of the hermitage.
