Bala Kanda (बालकाण्ड; IAST: ', Incident of childhood) is the first book of the Valmiki Ramayana, which is one of the two great epics of India (the other being the Mahabharata). There has been debate as to whether Bala Kanda was composed by the original author Valmiki or a later addition. The book consists of seventy-six sargas (sometimes translated as chapters or "cantos") of Sanskrit verse. The Bāla Kāṇḍa begins with the sage Vālmīki asking Nārada if there is a righteous man still left in the world, to which Nārada replies that such a man is Rāma. After seeing two birds being shot, Vālmīki creates a new form of meter called śloka, and then is granted the ability to compose an epic poem about Rāma. He teaches his poem to the boys Lava and Kuśa, who recite it throughout the land and eventually at the court of king Rāma, which then begins the main narrative. The king of Kosala, Daśaratha, lives in Ayodhyā, a utopian city, however he has no son. He and his court resolve to bring the sage R̥śyaśr̥ṅga in order to grant him sons. After the performance of an Aśvamedha (Horse Sacrifice), R̥śyaśr̥ṅga performs a Putrīyā Iṣṭi for the attainment of sons. Meanwhile the gods have petitioned to Brahmā and Viṣṇu about Rāvaṇa, a rākṣasa who has been oppressing rṣis, yakṣas, gandharvas, asuras, and brāhmaṇas. Due to a boon from Brahmā, Rāvaṇa is invincible to all beings except humans, so Viṣṇu decides to be born as the sons of Daśaratha. Back at the sacrifice outside Ayodhyā, a being emerges from the sacrificial fire carrying a celestial porridge. The being tells Daśaratha to distribute the porridge amongst his wives in order to bear sons. At the same time, Brahmā orders the gods to father monkey-sons who will assist Rāma later in the epic to defeat Rāvaṇa. After distributing the porridge, Daśaratha's wives Kausalyā, Kaikeyī, and Sumitrā bear Rāma, Bharata, and the twins Lakṣmaṇa and Śatrughna respectively. Years later, the sage Viśvāmitra arrives in Ayodhyā.
